Napromienianie całego ciała – przegląd technik

Abstract

Total body irradiation aims at preparing the patient for a bone marrow transplant. Various schemes of fractionation doses have been developed. Each scheme is adjusted according to the diagnosis and technical capabilities of given entity. The main difficulty is small size of the irradiation field which limits the patient's positioning. It is possible to obtain the field dimension 50 × 200 cm thanks to significant averting the patient from the radiation source. Another important factor is to obtain regular distribution of dose and simultaneously its reduction in critical organs such as the lungs. When it comes to the lateral fields, the organic class plate is commonly used. This plate allows radiating more superficial layers of the body. During patient positioning in the position AP/PA, the best solution is to reduce the thickness of the field. The process of total body irradiation (TBI) should be comfortable for the patient. His/her position should be fully reproducible.

The aim of the study is to present the whole body irradiation techniques, potential complications, side effects and patient positioning during the treatment.
