阅读说明：本技术 使用功率损失密度和相关测量来定量肿瘤治疗场（ttfields）的剂量 (Quantification of dose in Tumor Therapy Fields (TTFIELDS) using power loss density and related measurements ) 是由 Z·博姆聪 H·S·赫什科维奇 A·纳韦 S·莱维 N·乌尔曼 于 2019-07-18 设计创作，主要内容包括：通过获得身体部分的图像,并且基于该图像生成电导率的3D模型,可以改善在受试者的身体的一部分(例如,受试者的头部)中,使用肿瘤治疗场(TTFields)的治疗计划。鉴定3D模型内的靶体积,并且在给定位置处将一组模型电极加入3D模型中。然后,对于靶体积中的每个体素,确定最终应用TTFields时将存在的功率损失密度(PLD)。对于多个不同的电极位置重复相同的过程。最后,选择产生最佳PLD的一组电极位置,并且输出那些位置的描述。(Treatment planning using tumor treatment fields (TTFields) in a portion of a subject's body (e.g., the subject's head) may be improved by obtaining an image of the body portion and generating a 3D model of the electrical conductivity based on the image. A target volume within the 3D model is identified and a set of model electrodes is added to the 3D model at a given location. Then, for each voxel in the target volume, the Power Loss Density (PLD) that will exist when the TTFields are finally applied is determined. The same process is repeated for a plurality of different electrode locations. Finally, a set of electrode locations is selected that produces the best PLD, and a description of those locations is output.)
