The LCD display (6) is placed in the radiation path between the radiation source (4) and the patient (2) and the area or areas (3) is/are marked on the patient, guided by the illuminated depiction shaded edge areas. The depiction of one or more areas is created from an illumination picture (9) of the radiation target (1). The pre-created depiction is modified by adjustment to one or more field forms stored in advance, interactive modification directly on the picture screen (8), or mixt. of signals from illumination of the radiation target with information covering other field forms. The field shadow, created by the LCD display, is mixed and superimposed with signals from a picture enlarger (7), so that on the illumination picture it is possible to observe the area to be treated. The pre-created depiction is obtained from pictures taken with a computer tomographic simulator. |
