Abstract
Actually CT-cross-sections are the best base for irradiation planning. Bases are represented to use CT-picture matrices of scanner TOMOSCAN CX (Philips) for irradiation planning. The direct application of CT-pictures is done in "off-line"-running with the magnetic tape set. For figuring on colour display and estimation of density matrix limits of Hounsfield values are given. Adjustment of the CT to take off scan planes requires a special work-regime for irradiation planning. Repair and use of defective CT-pictures are realized by input of specific outlines. In daily routine the output of sagittal dose distribution is most advantageous in form of a table. Application of this CT-irradiation planning system, being implemented on microcalculator K 1630, is shown for telecobalt irradiation of mammary carcinoma.
