We describe a simple procedure of craniospinal irradiation in supine position. The procedure was carried out with a 100-cm isocenter linear accelerator and compatible simulator. Treatment was with a 1 or 2 posteroanterior (PA)-directed spinal fields abutting lateral-directed cranial fields. Abutment of the fields was established by placement of markers on the neck of the patient, which provided a measure of the divergence of the spinal field. The precision and reproducibility of this technique, including the placement of junctions, appeared to be as good as for treatment in the prone position. The same could be verified with port films. We conclude that this new technique of supine craniospinal treatment is a simple and convenient alternative to traditional treatment in the prone position.
我们描述了一种在仰卧位进行颅脊髓照射的简单方法。该方法使用一台等中心距离为100厘米的直线加速器和配套的模拟定位机进行。治疗采用1个或2个后前（PA）方向的脊髓野与侧方方向的颅野相邻。通过在患者颈部放置标记物来确定野的相邻，这提供了脊髓野发散度的一种测量方法。包括野衔接处放置在内的该技术的精度和可重复性，似乎与俯卧位治疗一样好。通过射野片也能证实这一点。我们得出结论，这种仰卧位颅脊髓治疗新技术是传统俯卧位治疗的一种简单且便捷的替代方法。
