埃迪科软件可以将电解剖图导入到心脏放射性废除的治疗计划系统中. 这种工具可以提高目标体积的划分和工作流程的效率,用于治疗心室动脉冲动.
科学领域:
- 医学物理 医学物理
- 心脏病学 心脏病学
- 辐射疗法 辐射疗法
背景情况:
- 心脏放射除 (CRA) 是一种新兴的治疗方法,用于耐火性心室性心跳动.
- 目前的工作流程缺乏将电解剖图导入治疗计划系统 (TPS) 的本地方法.
研究的目的:
- 开发Edico,这是一个半自动导入电解剖图到TPS的工具.
- 将电解剖图转换为DICOM格式,以简化目标体积的划分并提高工作流程的效率.
主要方法:
- 埃迪科将电解剖图数据 (电压,空间) 处理成符合DICOM标准的voxels.
- 进行了voxel大小灵敏度分析,以尽量减少平均值时的数据损失.
- 用Edico处理的地图注册计划CT扫描,重新划分了临床目标和规划目标体积.
主要成果:
- 埃迪科成功处理了测试电解剖图,保持了预期的特征.
- 对于Edico处理,最佳的voxel尺寸类似于或小于计划CT的voxel尺寸.
- 追溯分析显示,80%的目标量需要使用Edico生成的地图进行调整.
结论:
- 埃迪科为CRA提供了一种可靠的解决方案,用于将电解剖图导入TPS.
- 该工具有助于在CRA程序中准确识别临床和规划目标体积.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
