FD Pulse

The only mini c-arm with pulsed fluoroscopy

BEST OF BREED CHRISTIE INNOMED

Summary

The OrthoScan FD Pulse, with Flat Detector and pulsed fluoroscopy, is the new standard in mini C-Arm imaging and the culmination of more than 10 years' study of extremity surgical procedures. Equipped with a 15x15cm flat panel detector in place of the conventional image intensifier, the OrthoScan FD Pulse releases valuable space in the operating room. The ultra-compact system design, approximately 50% smaller and 25% lighter than conventional units, allows maximum manoeuvrability and ease of movement and has the thinnest flat panel detector on the market. A greater C-Arm arc depth provides the surgeon with the additional space to work more comfortably and the increased orbital rotation provides greater positioning options. The slim profile of the flat detector provides additional positioning options and better access, and other thoughtful features include integrated LED field lights built into the underside of the X-ray generator to eliminate shadows.

Technology

Pulsed Fluoroscopy


How Pulsed Fluoroscopy Works?


The human eye detects motion at 30 frames per second. This is the speed at which OrthoScan, television, and movies project motion to the audience. Moving from continuous fluoroscopy to a pulsed fluoroscopy of 30 pulses (pps)/frames per second (fps), OrthoScan is able to reduce the dose by 30% during live fluoroscopy without loss of image quality or detail. Selectable frames/pulses per second, between 30, 15, and 7.5 pps/fps, allow the user to reduce the dose between 30% and 80% depending upon their imaging needs.


Pulsed Fluoroscopy emits an x-ray beam as a series of short pulses rather than a continuous flow of x-rays. By reducing the amount of time x-rays are emitted, the system will produce a dose 30-80% less than a continuous stream of x-rays.


In addition to the reduced dose of Pulsed Fluoroscopy, this technology also allows for a more fluid motion display. By rapidly turning on and off the x-rays, the system is better able to adjust to the different densities presented during live fluoroscopy. This offers the user the highest quality motion study available on a mini c-arm.
 



Generation 5 CMOS Detector


Photons are used more efficiently, earlier in the image acquisition process (during lower ranges of the technique factors).


Provides more brightness
Provides a faster ramp time
Allows the user to use less dose


The previous generations use a higher dose to put more photons in the image for more brightness. The competition has the previous generation.


 







Flat detector


OrthoScan’s new mini c-arm with flat detector offers surgeons increased image quality, a smaller thin design, improved reliability, and more efficient imaging. Once again OrthoScan is setting the new standard in mini c-arm imaging.


How Flat Detectors Work?


Digital devices are smaller and more robust. Just as digital technologies have dramatically improved home audio and video fidelity, digital X-ray technology offers significant improvement in image quality and dose utilization. Standard fluoroscopy is still primarily based on analog technology, specifically, the image intensifier. Flat detectors have emerged as the next generation of digital X-ray technology.


Current image intensifier based imaging has many stages in the signal conversion chain. These stages result in geometric distortion and brightness non-uniformity across the diameter of the image. In comparison, flat panels have a direct, short signal conversion path, with essentially no optics. The result is a flat, uniform image from edge to edge.


 


 


Detector Technologies


Flat detectors are based on solid-state integrated circuit technology. The two primary detector technologies considered for fluoroscopy are thin-film-transistors (TFT) and complementary metal oxide semiconductor (CMOS). OrthoScan chose to use CMOS technology because of its higher frame rate and low inherit visual noise in the signal. Typically TFT technology presents limitations when used in mobile fluoroscopy including limited frame rates and image lag (ghosting).


Flat Detector Equals Higher Efficiency


Flat detector technology makes more efficient use of the available radiation. Flat detectors read more of the individual x-rays, so in turn there is less waste. Detective Quantum Efficiency (DQE) is the yardstick by which the performance of imagers is measured. A higher DQE translates directly into better imager quality for a given dose.

Benefits

30-80% Dose Reduction



Selectable frames/pulses per second (30, 15, & 7.5 pps/fps) allow the user to reduce the dose 30%–80% depending upon imaging needs.
 


Flat-Form Design



OrthoScan FD Pulse offers the flattest detector (2") on the market. This Flat-Form design provides optimal positioning in the surgical environment. It enables the surgeon to place the detector on top of the operating surface to obtain images without stressing the anatomy. The small detector housing creates a less invasive workspace without sacrificing field of view.
 


35% Larger Flat Detector


    


The square-shaped CMOS detector in FD Pulse provides the largest field-of-view in either direction. Image more anatomy without the need for a rotating receptor.
 


26% Larger Image


    


FD Pulse provides the only non-binned 1 x 1 image, enabling the user to make accurate measurements from the image. FD Pulse uses every pixel from the detector, broadcasting 200% more pixels to the screen.
 


Surgical LED Lights


    


Located on the bottom of the tube head, these surgical lights provide additional illumination on the anatomy and eliminate shadows cast from the tube head.
 


Bilateral Sterile Field Controls


    


Conveniently located on each side of the tube head assembly, bilateral controls provide easy access to imaging and documentation in the sterile field.
 


Over-Rotation


    


The OrthoScan FD Pulse design allows for an orbital rotation of 150 degrees. This enables the user to take advantage of the larger field of view without making mechanical adjustments required by competitive equipment.
 


Optimal Positioning


    


The increased orbital movement enables preferred views without stressing anatomy.
