Chiropractic · Long-length DR
Long-Length, Full-Spine, and Long-View DR for Chiropractic
If you want the short version: for most chiropractic full-spine rooms I start with the 2020 Imaging Universal 17×48. One exposure, a preview in under six seconds, and the measurement tools you already use. The other three are here because a real room sometimes needs a different answer. The detail is below if you want it.
Clinics ask for this four ways. A long-length panel. A full-spine detector. A long-view image. A long-form receptor. In an upright room those words are the same job — the whole spine in one exposure, not three 17×17 cassettes stitched after the patient has already shifted.
I walk the room in the order I would actually recommend it. 20/20 Imaging 17×48 is the easy fit. Fujifilm FDR D-EVO GL is next, usually because the office already lives in Fujifilm. Vieworks 17×51 when the requirement is simply more length. iCRco iDR-L so the scanning system is on the same page as the flat panels. The matrix stays in sheet order. A dash means that figure was not published. It is not a zero. Prices stay off this page.
Quotes stay private. Call 720-600-3117. Generator and room fit are confirmed before a number goes out.
Panel matrix
Columns stay in sheet order: 2020 Imaging, Vieworks, Fujifilm, iCRco. They are equal width. The holder and grid rows are from the 2020 quote. Choose a term and it opens the note below. Each note can return you to that same row, so you do not have to scroll back to the top. A dash means that figure was not published for that system. It is not a zero.
What those words mean for your room
The first bullet is the point. The second is there if you want the reason. Use Back to matrix when you are ready for the next term.
Type
Back to matrix- A flat panel makes the image in one exposure. A scanning system reads the plate after the exposure.
- The 2020, Vieworks, and Fujifilm detectors are amorphous-silicon flat panels. The iCRco iDR-L is a scanning phosphor-plate system. Both approaches cover a long spine. The difference is how the image is made and how the room is built around it.
Active Area (inches)
Back to matrix- This is how much of the patient you actually see.
- Longer is what keeps the skull or the sacrum from getting cut off. Vieworks is 51 inches, Fuji is 49, and the 2020 is 48. For most chiropractic full-spine work I still start at 48. Length is not the only reason to choose.
Active Area (mm)
Back to matrix- The same field of view, in millimeters.
- You only need it if you want to check the pixel math yourself. That arithmetic is in the section below.
Pixel Pitch (µm)
Back to matrix- How far apart the pixels are. A smaller number can hold finer detail.
- 139 and 140 microns are where modern long-length DR sits. Fuji’s 150 is a step coarser. The 100-micron figure belongs to the CR scanner, and only in its slowest mode.
Nyquist / Spatial Resolution (LP/mm)
Back to matrix- The finest detail the detector can theoretically record. Higher is finer.
- 3.5 to 3.6 line pairs is where these flat panels are published. The iCRco publishes 5.0 in its finest scan mode. A published line-pair number and the image on the reading station are worth looking at together, on every system.
Pixel Matrix (full)
Back to matrix- How many pixels are in the finished image.
- More pixels means more data, not automatically a better diagnosis. It is active area divided by pixel pitch. The 2020 matrix is not printed on the sheet. The math lands on 3064 × 8696.
Bit Depth
Back to matrix- How many shades of gray the detector can separate. 16-bit is 65,536 shades.
- All four are 16-bit. That is enough gray scale for diagnostic work, so this row is not what separates them.
Image Preview Time
Back to matrix- How long you and the patient wait before a usable image is on the screen.
- The 2020 is under six seconds. Fuji’s full-length preview is 9 to 20 seconds. The iCRco is about 55 seconds while the scanner travels the plate. Those are different workflows, and each one is a fit for a different room.
Full Image / Cycle Time
Back to matrix- How long until the full image is ready and you can take the next view.
- Vieworks is about 8 seconds to acquire and 15 before the next shot. Fuji’s full-length cycle is about 26 seconds. The iCRco stays near 55. Cycle time is part of how the day flows. It is one reason among several.
Weight
Back to matrix- What the detector, or the whole stand, weighs.
- In a fixed room this rarely decides the purchase. Vieworks and Fuji are both about 43 pounds. The iCRco wall stand is about 100 pounds, which is a different piece of equipment. The 2020 panel weight was not published, so I am not going to guess it.
Dimensions
Back to matrix- Whether the detector physically fits the stand and the wall you already have.
- I measure the wall and the stand with you before I say a detector will fit.
Scintillator
Back to matrix- The material that turns the X-ray into light the detector can record.
- Cesium (CsI) is what I want named on a long panel. It uses the exposure more efficiently than Gadox or GOS. Fuji uses GOS and recovers some of that with ISS. Ask which version you are being quoted. It changes the dose.
Data Interface
Back to matrix- How the image leaves the detector and gets to the computer.
- A tethered high-speed cable is what I want in a stand that never moves. Fuji also needs its power supply and cable run. The iCRco needs a trigger cable to the generator.
Trigger Method
Back to matrix- How the detector knows you just exposed.
- Automatic exposure detection works with most generators already in the room, without a new cable. A hard trigger is an install. I confirm which one your generator can do before I quote.
Wireless Option
Back to matrix- Whether the detector can work without a data or power cable.
- None of these four are wireless. On a 48-inch panel that lives in a wall stand, I do not miss it. Wireless earns its place on a cassette you carry from room to room.
X-ray Range
Back to matrix- The kVp range the detector is specified for.
- Where it is published, 40 to 150 kVp covers normal diagnostic spine work.
Power
Back to matrix- What has to be plugged in at the stand.
- Fuji wants its own power supply. Confirm the outlet before the panel is on the way. The others are simpler, and I still look.
Operating Environment
Back to matrix- The temperature and humidity the detector is rated for.
- A normal clinical room is inside that range. This is not a reason to pick one panel over another.
Warranty
Back to matrix- How long the manufacturer stands behind the panel.
- The 2020 panel is a 60-month manufacturer warranty. The others were not stated on this sheet. I confirm those on the quote instead of filling in a blank.
Chiropractic Software
Back to matrix- Whether the tools on the screen are the ones you already use on a film or a tracing.
- Symmetry-Sync, which many of you still call Opal-RAD, is the set I trust for this work: Gonstead, Blair, Orthospinology, Cobb, Penning, labeling, and stitching when a study still needs it. The other panels need a separate conversation about software.
Special Technologies
Back to matrix- The manufacturer’s own processing, dose tools, or scan modes.
- On the 2020, REALISM holds trabecular detail without asking the tube for a heavier exposure. Fuji’s ISS, Virtual Grid, and Dynamic Visualization are the reason an existing Fuji room stays Fuji. Vieworks can shoot 17×34 or 17×17 on the same panel without pulling it out of the stand.
Generator Compatibility
Back to matrix- Whether the panel will fire with the generator you already own.
- Most automatic-exposure panels work with generators already in the room. The iCRco is designed around a trigger cable, which is a planned part of that install. I look at the generator with you before a number goes out.
Manufacturer Location / Support Base
Back to matrix- Who answers the phone on the day the room is down, and where the part ships from.
- 2020 is in Crystal Lake, Illinois. iCRco is in Goleta, California. Fuji’s US office is in Lexington. Vieworks supports the US from Vernon Hills and builds in South Korea. A domestic answer is a shorter down day.
Full-Spine Holder
Back to matrix- What holds the detector on the wall, and whether you can move it for the patient in front of you.
- The 2020 quote includes the wall-mounted Trans-Former™ cabinet: 25 inches of vertical travel and a rotating pivot clutch that turns the panel 90 degrees. Fuji and Vieworks did not publish an equivalent holder on this sheet. The iCRco is the wall stand itself.
Grid
Back to matrix- The grid cleans scatter before it reaches the detector. That is what keeps a long-spine image from looking gray.
- The Trans-Former uses a removable 8:1, 103-line parallel grid. Parallel does not lock you to one source-to-image distance the way a focused grid does, which matters when the anatomy is this long. The other systems did not publish a matching grid here.
Best For
Back to matrix- The short version, after everything above.
- 2020 when the chiropractic tools and a single-exposure flat panel are the priority. Fuji when the room is already Fuji, or dose tools are the question. Vieworks when the longest field, and the shorter modes on the same panel, are what you need. iCRco when a US-made scanning wall stand is the system you want to compare.
How You Can Confirm The Numbers
The published numbers are here with the arithmetic beside them, so you can see how they were reached. The short version: they agree with the pitches and the areas. The 2020 pixel matrix is not printed in the grid above. The same math lands on 3064 × 8696.
| Check | Formula | Result |
|---|---|---|
| 2020 Nyquist | 1 / (2 × 0.139 mm) = 3.60 LP/mm | 3.6 LP/mm |
| Vieworks Nyquist | 1 / (2 × 0.140 mm) = 3.57 LP/mm | 3.5 LP/mm |
| Fuji Nyquist | 1 / (2 × 0.150 mm) = 3.33 LP/mm | 3.3 LP/mm |
| iCRco 100 µm Nyquist | 1 / (2 × 0.100 mm) = 5.0 LP/mm | 5.0 LP/mm |
| 2020 matrix check | 424 mm / 0.139 mm ≈ 3050; 1207 / 0.139 ≈ 8683 | Matches 3064 × 8696 |
| Vieworks matrix check | 432 / 0.140 ≈ 3086; 1295 / 0.140 ≈ 9250 | Matches 3072 × 9216 |
| Fuji matrix check | 8228 × 0.150 mm ≈ 1234 mm; 2832 × 0.150 ≈ 425 mm | Matches active area |
| Weight conversion Vieworks | 19.7 kg × 2.2046 ≈ 43.4 lb | 43 lb |
| DPI from 100 µm | 25.4 mm/in ÷ 0.1 mm = 254 DPI | 254 DPI |
| DPI from 155 µm | 25.4 / 0.155 ≈ 164 DPI | 163 DPI |
| DPI from 200 µm | 25.4 / 0.200 = 127 DPI | 127 DPI |
The arithmetic shows that the published figures agree with each other. Your generator, the wall, and the warranty language still get confirmed for your room before a quote.
2020 Imaging Universal 17×48 — where I start
If the office is done stitching, this is the panel I put on the table first. One exposure, the upright spine, and a preview in under six seconds — before the patient has time to ask whether they can step down. Cesium, 17 × 48 inches, 139 µm, 3.6 LP/mm, 16-bit. Scoliosis and a true full-spine lateral belong on this class of detector. There is no seam and no second shot to hold.
The software is the other half of the decision. Symmetry-Sync, which a lot of doctors still call Opal-RAD, already knows the work: Gonstead, Blair, Orthospinology, George's lines, Cobb, Penning, spine labeling, and stitching when a study still needs it. REALISM™ is the processing that holds trabecular detail while the exposure stays modest. For a chiropractic room that wants those tools with the long panel, this is the combination I start with.
It stays tethered on purpose. In a wall stand that never leaves the wall, I want the cable. Wireless earns its place on a cassette you carry between rooms. It is not a missing feature here. The sheet calls this detector cassette sized. That means one long receptor, not a 14×17 that drops into the tray you already have. AED covers most generators already on the floor, which is why a retrofit is realistic. I still look at the generator before a number goes out.
The panel is half of the install. The holder I quote with it is the Universal DR wall-mounted Trans-Former™. It is a full-spine grid cabinet made for this detector: 25 inches of vertical travel, a rotating pivot clutch that turns the panel 90 degrees, and a removable 8:1, 103-line parallel grid. Parallel matters on a long spine because you are not locked to one source-to-image distance the way a focused grid is. The panel carries a 60-month manufacturer warranty. A published weight for the detector alone was not on the sheet, so I will not invent one.
20/20 Imaging is in Crystal Lake, Illinois, a division of Konica Minolta Healthcare Americas. US support is part of what I look at on the day a detector is down, along with the warranty and how the part actually ships. See the 17×48 full-spine panel, the 20/20 Imaging page, and Symmetry-Sync. If the room is ready to be measured, the 17×48 room survey is the next step.
Fujifilm FDR D-EVO GL — a strong reason to stay with Fuji
Fujifilm’s long-length detector is the FDR D-EVO GL: 17 × 49 inches, 150 µm, 3.3 LP/mm, GOS with ISS (irradiated side sampling). I bring it up when the practice already works in Fujifilm, or when dose tools are the priority. It has its own length, its own processing, and a workflow that a Fuji room already understands.
A full-length preview is 9–20 seconds, about 6 seconds on a 17×17 segment. The full cycle is about 26 seconds, or 10 on that smaller segment. Weight is about 43 lb. The detector is about 52.7 × 22.3 × 2.0 inches. It is wired: RS232C to the power unit, Ethernet to the workstation, and its own 120 VAC supply. There is no wireless version. Those are the published figures, and they are part of planning the day, not a reason to dismiss the panel.
The Fujifilm toolset is a real reason to choose it. ISS is how a GOS plate makes use of the exposure. Virtual Grid is Fujifilm’s published claim of up to 50% dose reduction versus a physical grid. Dynamic Visualization and the noise-reduction circuitry (listed at 1.7× DQE) belong to the same story. SmartSwitch is automatic exposure detection, so most generators do not need a new trigger cable. I still confirm the generator with you. Warranty language was not on this sheet, so it is confirmed on the quote.
Fujifilm Healthcare Americas is in Lexington, Massachusetts. The parent company is in Japan. A US office matters on the day a panel is down. More Fujifilm equipment we sell and service is on the Fujifilm page. The G80i is a different, shorter long-view detector — do not mix the two.
Vieworks VIVIX-S 17×51 — the long one
If the requirement is inches of anatomy, the Vieworks VIVIX-S 1751S wins the tape measure. Active area is 17 × 51 inches (430 × 1290 mm), and the 17×34 and 17×17 modes do not require moving the panel. Pixel pitch is 140 µm, Nyquist 3.5 LP/mm, full matrix 3072 × 9216, 16-bit. That is a modern flat panel, close to the 2020 on sampling, and longer than both the 17×48 and the Fuji 17×49.
Acquisition is about 8 seconds, with a 15-second recommended cycle. Scintillator is CsI or Gadox. Both are real options. The version on the quote changes how the panel uses the exposure, so I name it before we go further. The panel is about 19.7 kg (43 lb) and 135.7 × 53.2 × 3.0 cm. Power is DC 24 V at 3.0 A. The stated range is 40–150 kVp, which covers diagnostic spine work. Data is Gigabit Ethernet. Trigger is a DR trigger or AED. Both are checked against the generator in the room. There is no wireless option.
Chiropractic measurement software is a separate choice with this detector, and that is fine. The hardware feature that stands on its own is multi-scan: a long spine, a shorter section, or a 17×17 region without pulling the panel out of the stand. For a room whose first requirement is the longest field of view, this is the panel I put next to the tape measure.
Vieworks is headquartered in Anyang, South Korea, with US support in Vernon Hills, Illinois. The US office is what keeps parts and a person on this continent. Warranty was not published in this matrix. Confirm it, and confirm which scintillator, before the quote is treated as final. Service context is on the Vieworks page.
iCRco iDR-L — the scanning long-length system
The iDR-L is iCRco’s long-length system, and it belongs in this comparison. It is a scanning phosphor-plate design — CR — built as a tall wall stand rather than a flat-panel detector. The scan area is 17 × 51 inches, which puts it with the longest fields on this page. Practices that want a scanning system, or that are deciding between CR and DR with the facts in front of them, can read it here beside the flat panels.
Selectable scan modes are 100, 155, and 200 µm, published as 5.0, 3.1, and 2.8 LP/mm. Five line pairs is the highest published resolution in this comparison, and it is the mode that takes about 55 seconds while the scanner moves across the receptor. That is the trade you are choosing: resolution and a scanning read, rather than a flat-panel preview. Laser spot size and plate characteristics are part of any CR image, the same way pixel pitch is part of any DR image.
The wall stand is about 100 lb. It is the imaging system, not a cassette you drop into a stand you already own. It uses a hard trigger cable to the generator, which is how this design knows an exposure happened. There is no wireless option. Chiropractic measurement software would be chosen separately.
iCRco builds in Goleta, California, with support listed Monday through Friday, 8am–6pm Pacific. A US manufacturer is a practical advantage for hours, shipping, and parts. For a typical chiropractic full-spine room that wants a flat-panel preview and the measurement tools in the same system, I still start with the 2020. When the practice wants this scanning wall stand, I quote the iDR-L on its own terms.
What has to be true before a quote
The generator and the room get checked against the equipment already on the floor. AED panels usually work with most generators. The iCRco does not — it wants a trigger cable. Fuji wants its power supply and cable run. The 2020 and the Vieworks want a straight answer on AED versus a DR trigger. Wall space, ceiling height, and whether the existing stand can hold the detector get measured, not assumed.
Where the company sits changes a down day. 2020 in Crystal Lake and iCRco in Goleta are US companies. Fujifilm’s US office is in Lexington. Vieworks supports the US from Vernon Hills and builds in South Korea. Each of those is a real support path. I tell you which one you are buying before the spec line is the only thing on the table.
I do not publish prices. A long-length room is quoted for that generator, that stand, and that software. Call 720-600-3117 or send the room details. The chiropractic page covers the rest of the upright room — straight-arm, DDR, and a cassette-sized upgrade when a 17×48 is more panel than the practice needs.
Questions clinics ask
What is a long-length or full-spine DR panel?
It is a single detector tall enough to cover a standing spine in one exposure. Clinics also call it a long-view or long-form panel. A 17×17 cassette cannot do that without stitching.
Is stitching three 17×17 images the same as a long-length detector?
No. Stitching is a workflow: three exposures, patient motion between them, and a software seam. A long-length flat panel is one exposure and one image.
Which long-length panel fits most chiropractic offices?
The 2020 Imaging Universal 17×48. It is a cesium flat panel, preview is under six seconds, and Symmetry-Sync is built for chiropractic measurement. The generator still has to be checked before anyone quotes it.
When would Fujifilm or Vieworks be the better fit?
Fujifilm FDR D-EVO GL belongs in a room that already lives on Fujifilm, or when the dose-reduction tools are the priority. Vieworks VIVIX-S 17×51 is the longest field of view, with 17×34 and 17×17 modes on the same panel.
Is the iCRco iDR-L a flat-panel DR detector?
No. It is iCRco’s scanning phosphor-plate wall stand, with a 17×51 scan area. The published 5 LP/mm figure is its finest scan mode, and a full-resolution read is about 55 seconds. It is a different way to make a long-length image, and it is on this page so you can compare it with the flat panels.
