应用Varian公司的Portal Dosimetry系统和ScandiDos公司的Delta4三维半导体阵列对Varian 23EX加速器固定剂量率旋转调强(CDR-VMAT)计划进行验证并对比分析。方法:随机选取10例头颈部肿瘤患者、10例胸部肿瘤患者和10例腹部肿瘤患者,采用RayStation计划系统在Varian 23EX加速器上设计CDR-VMAT。照射野根据肿瘤部位合理设计,射线能量...
Purpose: The dosimetric accuracy of the recently released Acuros XB advanced dose calculation algorithm (Varian Medical Systems, Palo Alto, CA) is investigated for single radiation fields incident on ...
Abstract: Purpose : To relate the physical transmittance parameters of the water equivalent Gafchromic EBT 2 Film with the delivered dose in a transparent absolute calibration protocol. The protocol s...
The optically stimulated luminescent (OSL) radiation dosimeter technically surveys a wide dynamic measurement range and a high sensitivity. Optical fiber dosimeters provide capability for remote monit...
Control radiation dose-response curves are necessary in evaluating the absorbed radiation dose of similar radiation quality following radiation accidents or in monitoring the health of both the public...
A personal UV dosimeter that can quantitatively assess high exposure solar UVA exposures has been developed. The chemical polyphenylene oxide has been previously reported on its ability to measure hig...
Background: Radiotherapy of prostate carcinoma often results in high doses to surrounding structures, such as the rectum and bladder. Therefore, these organs should be closely monitored. The aim of th...
