Varian Medical Systems To Introduce Two New PaxScan® Flat-Panel Digital Imaging Subsystems at RSNA This Year

PALO ALTO, Calif. — November 22, 2004 — Varian Medical Systems, Inc. (NYSE: VAR), a world leader in X-ray tubes and a premier supplier of the PaxScan® line of flat-panel digital X-ray image detectors, will introduce two new PaxScan products at the Radiological Society of North America (RSNA) meeting in Chicago later this week:

  • The PaxScan 2020 is designed for the cardiac and conventional C-arm market.  A small panel offering enhanced real-time imaging capabilities, it is ideal for applications utilizing 9-inch image intensifier tubes.  It incorporates a fast command processor and is optimized with extended memory for operating in different acquisition modes, from 1 to 60 frames per second.  The active imaging area is close to the panel’s edge, for unrestricted access to the patient.  An optimized pixel structure ensures low image lag and an improved signal-to-noise ratio.
  • The PaxScan 4030CB meets the needs of the emerging cone-beam cross-sectional X-ray imaging market.  This panel is a key component of Varian’s radiation oncology imaging and treatment technologies, including the Acuity™ radiotherapy simulation and verification device and the On-Board Imager™ accessory for real-time image-guided radiation therapy.  It is ideal for medical diagnostic X-ray equipment requiring a large 20-inch diagonal imaging area.  The 4030CB is based on Varian’s flagship PaxScan 4030A product, which has a 40 x 30 cm imaging area and a 194-micron pixel pitch.  These panels offer excellent low-dose performance, achieved through Varian's proprietary readout electronics and a highly sensitive cesium iodide scintillator.  They can acquire high-resolution fluoroscopic images at up to 30 frames per second and radiographic images up to 7.5 FPS.

Each PaxScan digital imager incorporates a flat panel amorphous-silicon sensor array, a command processor, a power supply, and all interconnecting cables. In addition to these new products, Varian will exhibit the company’s full line of X-ray tubes at the RSNA show, as well as the company’s cancer treatment technologies.   The RSNA exhibits run from Sunday, November 28 through Thursday, December 2, at McCormick Place in Chicago.
