The computer program that controls this automated dosimeter system has been designed to acquire and display data directly in the format specified by the AAPM TG-43 protocol for calculating brachytherapy seed dose distributions in terms of radial dose function and anisotropy function. Results: The dose...
The updated protocol ͑TG-43U1͒ includes ͑a͒ a revised definition of air-kerma strength; ͑b͒ elimination of apparent activity for specification of source strength; ͑c͒ elimination of the anisotropy constant in favor of the distance-dependent one-dimensional anisotropy function...
, 1.0, 1.5, and 2.0 cm, respectively. While not the case with this dataset, there may be minor differences in values presented in TG-43U1 compared to values published in the publications from which candidate datasets were derived. Slight differences were expected as interpolation was used to o...
The updated protocol (TG-43U1) includes (a) a revised definition of air-kerma strength; (b) elimination of apparent activity for specification of source strength; (c) elimination of the anisotropy constant in favor of the distance-dependent one-dimensional anisotropy function; (d) guidance on ...

剂量分布临床应用放射性粒子治疗恶性肿瘤有100多年的历史.文章从平方反比定律,剂量率效应,放射源周围的剂量分布三方面介绍了放射性粒子的基本剂量学特点,阐述了AAPM TG-43报告,并针对AAPM TG43标准的Monte Carlo进行模拟研究.AELPM TG-43号报告提出了放射性粒子在人体组织内剂量分布的计算标准,近些年针对报告中提出的...
Since publication of the 2004 update to the American Association of Physicists in Medicine (AAPM) Task Group No. 43 Report (AAPM TG- 43U1), several new low-energy photon-emitting brachytherapy sources have become available. Many of these sources have satisfied the AAPM prerequisites for routine ...
在1983年底由AAPM(American Association of Physicists in Medicine)之放射治療委員會(Radiation Therapy Committee)指派Task Group 21所完成的對高能光子與電子射束之劑量校正文獻,本科於民國七十五年做詳細的校正測量評估之後,自七十六年元旦起開始使用於臨床作業.本篇是將TG-21文獻與SCRAD,ICRU 21號報告等舊有文獻,對...
