Conclusions
1. In intracavity moving-beam and multipositional irradiation it is possible to produce dose fields with practically straight isodose sections, but the maximum possible distance from the straightened-out dose section to the source trajectory decreases with an increasing number of points on the straight line through which the isodose section must pass.
2. The greater the distance between the straightened-out dose section and the source trajectory, the higher the ratio of absorbed doses near the ends and center of the trajectory.
