Report

The dual-dose imaging technique: a way to enhance the dynamic range of X-ray detectors

Autor: Matsinos, Evangelos, Kaissl, Wolfgang

We describe a method aiming at increasing the dynamic range of X-ray detectors. Two X-ray exposures of an object are acquired at different dose levels and constitute the only input data. The values of the parameters which are needed to process these

Report

The geometric calibration of cone-beam imaging and delivery systems in radiation therapy

Autor: Matsinos, Evangelos, Kaissl, Wolfgang

We propose a method to achieve the geometric calibration of cone-beam imaging and delivery systems in radiation therapy; our approach applies to devices where an X-ray source and a flat-panel detector, facing each other, move in circular orbits aroun

Report

The dual-gain mode: a way to enhance the dynamic range of X-ray detectors

Autor: Matsinos, Evangelos, Kaissl, Wolfgang

Varian Medical Systems has manufactured and recently put into operation a clinically-applicable solution for image-guided radiation therapy. Cone-beam CT imaging, one of the operation modes of the imaging unit of this device, aims at high-quality vol
