[Determination of the law of radiation source motion in intracavitary moving and multipositional irradiation].
The intracavital moving and multipositional irradiation with portable sources in gamma-therapy of extended pathologic foci offers more possibilities for the formation of dose distribution in accordance with the patient's individual features. A method is proposed to calculate the movement law for the point and linear irradiation sources following the preset dose distribution. The authors show possible formation of dose fields with a practically rectilinear isodose portion.
