Survey results of 3D‐CRT and IMRT quality assurance practice

Quality Assurance of IMRT delivery systems – Varian

Introduction Intensity modulated radiation therapy (IMRT) provides the means for improved treatment for a wide variety of cancers. Piggybacked onto 3DCRT and MLC technologies, IMRT has developed quickly, but will undoubtedly see improvements in core hardware and software as well as in peripheral applications such as record and verify, gating, etc. At the core, individual treatment centers shoul...

Quality Assurance and Good Manufacturing Practice in Respect of Plasma Fractionation

Comparison of two commercial detector arrays for IMRT quality assurance

Two commercially available detector arrays were compared for their use in the quality assurance of patient-specific IMRT treatment plans: one a diode-based array (MapCHECK) and the other an ion chamber-based array (MatriXX). The dependence of the response of detectors on the field size, dose rate, and radiation energy were measured and compared with reference measurements using a Farmer-type io...

Evaluation of a 2D diode array for IMRT quality assurance.

BACKGROUND AND PURPOSE The QA of intensity modulated radiotherapy (IMRT) dosimetry is a laborious task. The goal of this work is to evaluate the dosimetric characteristics of a new 2D diode array (MapCheck from Sun Nuclear Corporation, Melbourne, Florida) and assess the role it can play in routine IMRT QA. MATERIAL AND METHODS Fundamental properties of the MapCheck such as reproducibility, li...

Quality Assurance in Archaeological Survey

To have confidence in the results of an archaeological survey, whether for heritage management or research objectives, we must have some assurance that the survey was carried out to a reasonably high standard. This paper discusses the use of Quality Assurance (QA) approaches and empirical methods for estimating surveys' effectiveness at discovering archaeological artifacts as a means for ensuri...
