Recent contributions to planning therapeutic irradiations

The computerized treatment planning programs, indispensable for up-to-date irradiation of deepseated malignancies, must take the influence of ever-greater numbers of physical factors into consideration and they make necessary the specification of ever-more optional factors. For this reason, we have attempted to develop a program also including optimization, on the one hand, and have checked with direct measurements whether the generally used methods in determining dose distribution take the surplus doses (produced by inclined irradiation) correctly into consideration, on the other.
