To quantify and verify the dosimetric impact of high‐dose rate (HDR) source positional uncertainty in brachytherapy, and to introduce a model for three‐dimensional (3D) position tracking of the HDR source based on a two‐dimensional (2D) measurement. This model has been utilized for the development of a comprehensive source quality assurance (QA) method using radiochromic film (RCF) dosimetry including assessment of different digitization uncertainties.

HDR 192Ir源的位置和角度跟踪，用于使用放射致变色膜剂量法进行近距离放射治疗质量保证

为了量化和验证高剂量率（HDR）源在近距离放射治疗中的剂量学影响，并基于二维（2D）测量引入用于HDR源的三维（3D）位置跟踪的模型。该模型已用于开发使用放射色膜（RCF）剂量法的综合源质量保证（QA）方法，包括评估不同的数字化不确定性。
