Radiotherapy plan designing simulation and three-dimensional dose distribution testing device

一种放疗计划设计模拟和三维剂量分布测试装置

Abstract

本发明公开了一种放疗计划设计模拟和三维剂量分布测试装置,本装置通过定位标记珠及标记珠固定板,准确地确定A、B点的空间位置,在X光片或CT图像中,均能精确地显影,便于准确地确定剂量计算参考点;通过改变穹隆施源器固定板的放置位置、以及改变宫腔施源器固定板中定位孔的长度,以安放有效长度分别为4、6、8cm的宫腔施源器,即可模拟设计肿瘤近距离治疗的各种典型计划方案。通过宫腔施源器固定板中以及通过胶片固定板安放在内腔中其余不同位置的放射量测定胶片,可获得整个治疗计划照射的主要范围内、间距1-2mm的平行平面剂量分布,将所有平面剂量分布与计划系统设计的剂量分布进行比较,即实现空间中的三维剂量分布测试与验证。
The invention discloses a radiotherapy plan designing simulation and three-dimensional dose distribution testing device. The space positions of points A and B are accurately determined through a locating marking ball and a marking ball fixing plate via the device. In an X-ray film or a CT image, accurate development can be carried out, and dose computing reference points can be determined accurately and conveniently. By changing the placing position of a dome source applicator fixing plate and the length of a locating hole in a uterine cavity source applicator fixing plate, uterine cavity source applicators with the effective lengths being 4 cm, 6 cm and 8cm respectively are arranged, and various typical plan schemes of tumor close-range treating can be subjected to simulation designing. Through dosimetry films arranged in the uterine cavity source applicator fixing plate and at the rest of different positions in an inner cavity of a film fixing plate, parallel plane dose distribution in the main range of whole treating plan radiating at the space distance of 1 mm-2 mm can be obtained, the whole plane dose distribution is compared with dose distribution designed by a plan system, and three-dimensional dose distribution testing and verifying in a space are achieved.
