A method for the three dimensional location of lymph nodes with respect to the skin surface is described. The technique is based on the reconstruction of surface shape using isocentric radiographs taken with metal chains draped on the patient. Registration of the radiographic study to the lymphoscintigraphic study is accomplished automatically by matching the location of four radiopaque and radioisotope markers. This method allows nodes to be located in a beam's eye view with any set up of an isocentric radiotherapy machine. An accurate determination of the depth of lymph nodes is obtained, which is of value in electron beam therapy.
描述了一种确定淋巴结相对于皮肤表面三维位置的方法。该技术基于使用金属链披挂在患者身上拍摄的等中心射线照片重建表面形状。通过匹配四个不透射线和放射性同位素标记的位置,可自动完成射线照相研究与淋巴闪烁造影研究的配准。该方法允许在等中心放射治疗机的任何设置下,以射野视角定位淋巴结。可准确确定淋巴结的深度,这在电子束治疗中具有重要价值。
