DETERMINING ACTUATING VARIABLES, SETTINGS OR TECHNICAL PARAMETERS (PLANNING AID)

摘要

The invention relates to a planning aid for interactively selecting a radiotherapy plan from a database (1) with a multitude of pre-calculated plans serving as stored solutions. Each solution represents a radiotherapy plan consisting of a multitude of actuating variables (x1, y7, a1, a2, a3, I1, I2) that can be applied (6, 7) to a radiotherapy unit (10, 11, 12). Each solution also contains a number of characteristic values of radiation doses for tissue volumes (T, Target) and risk volumes (organ at risk, h1, h2, h3). At least three axes are visually displayed in the form of dose scales (31, 32, 33) on a display device (3; 3a, 3b) whereby forming at least three axes that do not fall atop one another. The characteristic values (51, 52, 53) of the radiation doses of a multitude of stored solutions for three of the four tissue volumes are respectively assigned to the three axes whereby resulting in an interval (a31, a32, a33) for each of these axes. Three intervals for the axes (31, 32, 33) that do not fall atop one another define, together, an emphasized planning zone (40; 41, 42). Another axis (34) can be seen as another dose scale outside of the planning zone (40).
