“…A third possible source of bias lies in the electronics of MatriXX, particularly the TERA chips, the charge measuring device. Cirio et al 23 have observed pedestal signals ͑signals in the absence of charge/current͒ of a few counts per second for these chips having history of cumulative doses less than 1000 Gy. Given the charge quantum ͑0.1 pC/count͒ and sensitivity ͑0.42 Gy/nC͒ of MatriXX, 22 a typical bias rate ͑e.g., in Fig.…”

The performance of MatriXX has been systematically evaluated in the peripheral dose regions. Major sources of error associated with MatriXX are identified and a correction method is suggested. This method has been successfully tested using both experimental and clinical plans. In all cases, good agreements between MatriXX and an ion chamber are achieved after corrections. The authors conclude that with proper corrections, MatriXX can be reliably used for peripheral dose measurements within the ranges studied.

Modern radiation therapy is very conformal, resulting in a complexity of delivery that leads to many small radiation fields with steep dose gradients, increasing error probability. Quality assurance in delivery of such radiation fields is paramount and requires real time and high spatial resolution dosimetry. Semiconductor radiation detectors due to their small size, ability to operate in passive and active modes and easy real time multichannel readout satisfy many aspects of in vivo and in a phantom quality assurance in modern radiation therapy. Update on the recent developments and improvements in semiconductor radiation detectors and their application for quality assurance in radiation therapy, based mostly on the developments at the Centre for Medical Radiation Physics (CMRP), University of Wollongong, is presented.
