X-Ray Tubes and Flat Panel Detectors Developed for Digital Radiography

A new range of next-generation X-ray tubes have been designed for digital imaging systems.

Varian Medical Systems (Palo Alto, CA, USA) presented their PaxPower X-ray tubes and PaxScan digital detectors at China International Medical Equipment Fair (CMEF) in Shenzhen, China, which took place rom April 14-20, 2012. Moreover, the company displayed its technologies for treating cancer with fast, image-guided radiotherapy and radiosurgery.

The new PaxPower FP tube platform was designed for space efficiency and high performance. “The lightweight anode-end grounded PaxPower tubes are half the size and have twice the power of conventional dual-ended tubes,” said Steve Kimmel, vice president sales and marketing for Varian’s X-ray products group.

Integrating the PaxScan X technology, the PaxScan 4343CB digital detector is designed to support both high quality radiography and state-of-the art dynamic imaging. The 4343CB enables dual-energy imaging and tomosynthesis in radiography, while also functioning in universal radiofrequency (RF) and large volume cone beam computed tomography (CBCT) applications. The large field-of-view panel features multiple sensitivity ranges, extended dynamic range modes, and a 139-µm pixel size for highly detailed images, excellent contrast, and spatial resolution, while delivering a low X-ray dose to the patient.

The midsize PaxScan 1515DX CBCT and panoramic imaging panel uses Varian’s new DX technology for advanced digital imaging within C-arm systems as well as dental and industrial applications. “Our PaxScan detectors make it possible to acquire high resolution images in real-time, for quick diagnoses and patient treatment,” said Mr. Kimmel.

The PaxScan 3024M compact dynamic detector design for full-field digital mammography utilizing tomosynthesis technology integrates a narrow border at the chest wall and rapid image-acquisition capability. “This new architecture, based on amorphous silicon [a-Si] technology, promises to extend the capabilities of digital mammography into emerging markets and mobile screening applications where its environmental stability makes it an attractive option over existing technologies,” said Mr. Kimmel.
