In vivo dose verification using using an amorphous silicon flat panel-type imager (a-Si EPIDs)

Introduction: Electronic portal imaging devices (EPIDs) could be used to dose verification of radiotherapy treatment plans. In vivo dose verification is performed to reduce differences found between dose delivered to the patient and the prescribed dose. The aim of this study was to perform a fast and efficient technique for the verification of delivered dose to the patient usin...

A-Si FLAT PANEL

Flat Panel Illustration In 2000, a large array A-Si flat panel EPID detector was installed (AL-7) on one of the PRIMUS accelerator at UCSF to allow for a comparison of performance. During the development period of MVCBCT, the introduction in 2004 of a new flat panel (AG-9) better optimized for high energy photons showed a several fold increase in sensitivity, allowing the routine acquisition of...

Focal spot measurements using a digital flat panel detector.

Focal spot size is one of the crucial factors that affect the image quality of any x-ray imaging system. It is, therefore, important to measure the focal spot size accurately. In the past, pinhole and slit measurements of x-ray focal spots were obtained using direct exposure film. At present, digital detectors are replacing film in medical imaging so that, although focal spot measurements can b...

Evaluation of the quality of CT-like images obtained using a commercial flat panel detector system

PURPOSE The development of flat panel detector technology has resulted in renewed interest in the possibility of generating CT-like images from rotational angiographic acquisitions. At least two commercial products now use cone beam reconstruction software in conjunction with flat panel detectors to produce such images. The purpose of the work presented here is to report on image quality obtain...
