Control of Respiratory Motion by Hypnosis Intervention during Radiotherapy of Lung Cancer I

الملخص EN

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.
