切伦科夫图像可用于全皮肤电子治疗(TSET)中剂量均匀度的质量保证。出于剂量映射的目的，本研究使用配准算法和计算机动画技术从3D扫描中重建患者模型。从多视角切伦科夫图像中提取患者面部的切伦科夫光发射，转换为剂量分布，并投影到患者的3D模型上，以便进行剂量累积和评估。多个切伦科夫相机的投影结果提供了有关患者两侧切伦科夫辐射的额外信息，这改进了切伦科夫转换剂量和OSLD测量之间的一致性。
Cherenkov images can be used for the quality assurance of dose homogeneity in total skin electron therapy (TSET). For the dose mapping purpose, this study reconstructed the patient model from 3D scans using registration algorithms and computer animation techniques. The Cherenkov light emission of the patient’s surface was extracted from multi-view Cherenkov images, converted into dose distribution, and projected onto the patient’s 3D model, allowing for dose cumulation and evaluation. The projected result from multiple Cherenkov cameras provides additional information about Cherenkov emission on the sides of the patients, which improves the agreement between the Cherenkov converted dose and the OSLD measurements.
