Stereotactic radiotherapy is a burden for the patients, when the frame is attached to the skull with a bolt to suppress the patient’s movement. We developed a device to obtain the head position and treat safely by using an optical device without losing the precision. After having verified the precision and safety on the basic experiment, the experiment was performed by the volunteers. As a result, we confirmed it practicable enough and had an expectation to the extensive application.

立体定向放疗对患者来说是一种负担，当框架用螺栓固定在颅骨上以抑制患者的运动时。我们开发了一种装置，可以在不失去精度的情况下，使用光学装置安全地获得头部位置和治疗。在基础实验上验证了精度和安全性后，由志愿者进行实验。结果表明，该方法是可行的，并对其广泛应用抱有期望。
