Description

Compensation device and compensation method for whole-body skin radiotherapy

Technical Field

The invention relates to the technical field of compensation devices for whole-body skin radiotherapy, in particular to a compensation device and a compensation method for whole-body skin radiotherapy.

Background

Whole body skin irradiation is a special radiotherapy technology for irradiating the superficial part of the whole body skin, the main purpose is to uniformly give a certain irradiation dose to the whole body skin, avoid the over-high dose of deep tissues, reduce the irradiation dose of organs except the skin, and improve the life quality of patients.

The whole body skin irradiation technology aims at the irradiation of the whole body skin part, needs to form superficial dose distribution on the whole body skin, has a wide irradiation range, needs to reduce the irradiated dose of other organs as much as possible, and reduces the side effect of radiotherapy.

The dose build-up effect causes a low dose area to appear on the tissue surface, in order to improve the irradiation dose of a superficial treatment target area and reduce the total irradiation dose received by a patient, when a radiation treatment scheme of superficial tumors is prepared, a tissue compensator is mostly adopted to increase the tissue thickness of an irradiation area of the patient, so that the radiation dose distribution is adjusted, the skin and subcutaneous dose are improved, the irradiation dose of OAR (anterior OAR) and the target area are better limited, and the prognosis effect of radiotherapy is improved. When whole body skin irradiation is performed, a compensation film is still required to be added on the surface of the whole body skin of a patient to meet the requirement of clinical target dose distribution. The skin of each part of the whole body of the patient is uniformly covered with the compensation film, and the fitting property of the compensation film and the skin is ensured. If the fit is not good, gaps exist between the compensation film and the skin, so that the dose distribution of the skin is greatly influenced, the problem of dose hot spots or cold spots is caused, and the treatment effect is not ideal.

The existing compensation mode is that hospitals in Taiwan area utilize rubber foaming materials to manufacture diving suits, but has the following defects:

1. the compensation film is divided into a plurality of parts such as a head cover, an upper garment, a lower garment, foot covers and gloves, so that the patient can not conveniently wear and take off the compensation film, and the compensation film is overlapped or omitted at the joint due to the multi-part structure.

2. Meanwhile, due to the influence of the characteristics of the material, the skin can not be really attached to the skin of the body of a patient during processing and manufacturing, and the skin receiving amount is not uniform.

3. The wearing and taking off are difficult, time-consuming and labor-consuming, and cause certain influence on the skin of the patient.

4. The manufacturing time period is long and the cost is high. Three weeks are required.

5. Along with the treatment, the body of the patient cannot meet the requirements of the original plan design after being changed, and cannot be adjusted in time.
