The uncertain position of lung tumor during radiotherapy compromises the treatment effect. To effectively control respiratory motion during radiotherapy of lung cancer without any side effects, a novel control scheme, hypnosis, has been introduced in lung cancer treatment. In order to verify the suggested method, six volunteers were selected with a wide range of distribution of age, weight, and chest circumference. A set of experiments have been conducted for each volunteer, under the guidance of the professional hypnotist. All the experiments were repeated in the same environmental condition. The amplitude of respiration has been recorded under the normal state and hypnosis, respectively. Experimental results show that the respiration motion of volunteers in hypnosis has smaller and more stable amplitudes than in normal state. That implies that the hypnosis intervention can be an alternative way for respiratory control, which can effectively reduce the respiratory amplitude and increase the stability of respiratory cycle. The proposed method will find useful application in image-guided radiotherapy.
在放疗过程中，肺部肿瘤的不确定位置会影响治疗效果。为了在肺癌放疗过程中有效控制呼吸运动而无任何副作用，一种新的控制方案——催眠术已被引入肺癌治疗中。为了验证该方法，选择了 6 名志愿者，他们的年龄、体重和胸围分布广泛。在专业催眠师的指导下，对每位志愿者进行了一组实验。所有实验均在相同的环境条件下重复进行。分别记录正常状态和催眠状态下的呼吸幅度。实验结果表明，催眠状态下志愿者的呼吸运动幅度比正常状态下更小、更稳定。这意味着催眠干预可以作为呼吸控制的一种替代方法，它可以有效地减小呼吸幅度，增加呼吸周期的稳定性。该方法将在图像引导放疗中找到有用的应用。
