In March 2004, the American Association of Physicists in Medicine (AAPM) published an update to the AAPM Task Group No. 43 Report (TG-43) which was initially published in 1995. This update was pursued primarily due to the marked increase in permanent implantation of low-energy photon-emitting brachytherapy sources in the United States over the past decade, and clinical rationale for the need of accurate dosimetry in the implementation of interstitial brachytherapy. Additionally, there were substantial improvements in the brachytherapy dosimetry formalism, accuracy of related parameters and methods for determining these parameters. With salient background, these improvements are discussed in the context of radiation dosimetry. As an example, the impact of this update on the administered dose is assessed for the model 200 (103)Pd brachytherapy source.
2004年3月，美国医学物理学家协会（AAPM）发布了AAPM第43号任务组报告（TG - 43）的更新版，该报告最初于1995年发布。进行此次更新主要是因为在过去十年中，美国低能光子发射近距离放射治疗源的永久性植入显著增加，以及在实施间质近距离放射治疗时准确剂量测定的临床依据。此外，近距离放射治疗剂量测定形式、相关参数的准确性以及确定这些参数的方法都有了实质性改进。基于这些显著的背景，在辐射剂量测定的背景下对这些改进进行了讨论。例如，针对型号为200（103）Pd的近距离放射治疗源，评估了此次更新对所施用剂量的影响。
