English(EN) Is Deformable Image Registration Ready for Brain Metastasis Reirradiation Dose Accumulation? A Longitudinal MRI Benchmark of Registration Accuracy

可变形图像配准精度不足以进行脑转移瘤再照射

一项新研究评估了可变形图像配准(DIR)方法在脑转移瘤再照射中累积辐射剂量的准确性。研究人员使用接受立体定向放射外科治疗的患者的纵向 MRI 数据,对各种基于学习和基于优化的 DIR 技术进行了基准测试。尽管基于优化的方法表现最佳,但即使是最先进的 DIR 方法,在这一背景下也未能达到未经监测的临床使用的足够精度,因此需要进行病例级质量控制。 AI

影响 当前的可变形图像配准方法需要进一步开发,才能在脑转移瘤再照射等复杂医疗场景中可靠使用。
