Varian公司一系列新型圓盤狀面板的數(shù)字X線影像探頭包含了設(shè)計(jì)用于心血管與傳統(tǒng)C臂領(lǐng)域的系統(tǒng)。

PaxScan2020系統(tǒng)提供了增強(qiáng)實(shí)時(shí)成像能力，適合應(yīng)用9英寸影像增強(qiáng)管。它整合了快速命令處理器并將擴(kuò)展存儲(chǔ)器最優(yōu)化，用于處理不相關(guān)的獲取模式，從1-60幀/秒?；顒?dòng)成像弧形裝置靠近面板邊緣，可以不受限制的靠近患者。最優(yōu)化象素結(jié)構(gòu)確保了低端影像遲滯并提高了信噪比。

PaxScan 4030CB系統(tǒng)設(shè)計(jì)用于新興的錐形光束橫斷面X線影像市場(chǎng)。這兩種探頭都是由Varian醫(yī)療系統(tǒng)公司(Palo Alto, CA, USA)研制開發(fā)的。這種面板是Varian腫瘤影像檢查和治療技術(shù)的主要組成成份，包括強(qiáng)烈放射治療模擬設(shè)備與確診設(shè)備，以及實(shí)時(shí)影像引導(dǎo)放射治療的成像設(shè)備。它還適用于需要大20英寸對(duì)角線成像區(qū)域的醫(yī)療診斷X線設(shè)備。

Digital X-ray Image Detectors
 
A new line of flat-panel digital x-ray image detectors includes a system designed for the cardiac and traditional C-arm fields.

The PaxScan 2020 provides enhanced real-time imaging capability, and is suitable for applications utilizing nine-inch image intensifier tubes. It incorporates a fast command processor and is optimized with extended memory for operating indifferent acquisition modes, from 1-60 frames per second. The active imaging arc 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 system is designed for the emerging cone-beam cross-sectional x-ray imaging market. Both detectors were developed by Varian Medical Systems (Palo Alto, CA, USA). This panel is a major component of Varian’s 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 suitable for medical diagnostic x-ray equipment requiring a large 20-inch diagonal imaging area.
