High-dose-rate (HDR) prostate brachytherapy is an established technique for whole-gland treatment. For transrectal ultrasound (TRUS)-guided HDR prostate brachytherapy, image fusion with a magnetic resonance image (MRI) can be performed to make use of its soft-tissue contrast. The MIM treatment planning system has recently introduced image registration specifically for HDR prostate brachytherapy and has incorporated a Predictive Fusion workflow, which allows clinicians to attempt to compensate for differences in patient positioning between imaging modalities. In this study, we investigate the accuracy of the MIM algorithms for MRI-TRUS fusion, including the Predictive Fusion workflow.

用于 TRUS 引导的 HDR 前列腺近距离放射治疗的 MRI-TRUS 配准方法

高剂量率 (HDR) 前列腺近距离放射治疗是一种成熟的全腺体治疗技术。对于经直肠超声 (TRUS) 引导的 HDR 前列腺近距离放射治疗，可以使用磁共振图像 (MRI) 进行图像融合，以利用其软组织对比度。MIM 治疗计划系统最近专门为 HDR 前列腺近距离放射治疗引入了图像配准，并结合了预测融合工作流程，使临床医生能够尝试补偿成像模式之间患者定位的差异。在这项研究中，我们调查了用于 MRI-TRUS 融合的 MIM 算法的准确性，包括预测融合工作流程。
