HDR brachytherapy is a is a kind of radio therapy that amongst other methods can be performed with interstitial needles. An important working step in this treatment is the fast and accurate implantation of several metallic pipe needles inside a tumour. In the procedure currently used in clinical routine a needle is placed stepwise by controlling the needle position and direction with newly acquired CT scans after every further insertion. This procedure is time consuming (1-2h for ca. 10-15 needles), therefore painful for the patient and relative inaccurate. The estimation of the necessary corrections of the needle direction is complicated and highly depends on the experience of the physician. Additionally the CT device is not available for other applications during this time. This work presents an application where the placement of the interstitial needles can performed fast and accurate by an image guided interactive navigation in a 3D CT data set of the patient.
