| Varian Medical offers the PaxScan 2020 for the C-arm market.
Varian Medical Systems at the forefront of new advances in fluoroscopy. The company manufactures the PaxScan flat-panel digital imager, an amorphous-silicon digital imager that can be used for digital radiography and fluoroscopy. Another new development is a device for image-guided radiation therapy, the On-Board Imager accessory. Using digital kV X-ray imaging technology to help clinicians deliver radiation therapy treatments more accurately, this device incorporates one of Varian's flat-panel imagers.
Varian Medical offers the PaxScan 4030 CB for the cone-beam diagnositic market.
All of Varian's flat-panel detectors are exclusively air-cooled imaging components, making the overall integration process simple for the system designer, less prone to field failure for the service technician, and dependable for the radiologist and patient. Varian provides all of its flat-panel detectors with corrected image output to the OEM's workstation.
Typically, the image corrections required involve compensating for slight variations in signal levels from channel to channel and certain pixel or line imperfections that have been known to create small image artifacts.
In Summer of 2003, Varian received FDA 510(k) clearance for an additional feature to the On-Board Imager that uses fluoroscopy to verify what the company calls "gated treatment plans," which are radiotherapy treatment plans for respiratory gating. The fluoroscopic mode of the On-Board Imager will enable physicians to see the patient's internal anatomy as it moves due to respiration as well as verify that the gated treatment delivery is going to adequately compensate for the tumor motion. |
