MEDICAL APPARATUS FOR DISPLAYING THE CATHETER PLACEMENT POSITION

摘要

The invention provides for a medical apparatus (200 300 400) comprising: a magnetic resonance imaging system (202) a display (270) a processor (228) and a memory (234) for storing instructions for the processor. The instructions causes the processor to receive a brachytherapy treatment plan (240) acquire (100) planning magnetic resonance data (244) calculate (102) a catheter placement positions (246 900 902) and a catheter control commands (248) the brachytherapy catheters. The instructions cause the processor for each catheter placement position to repeatedly: acquire (106) guidance magnetic resonance data (250) reconstruct (108) an image (252 500) display (110) the image and the catheter placement position on the display receive (114) a catheter inserted signal from a user interface segment (116) the image to determine the catheter placement position after receiving the catheter inserted signal recalculate (116) the catheter placement positions for each remaining catheter placement position after receiving the catheter inserted signal and recalculate (116) the catheter control command for all of the multiple catheters after receiving the catheter inserted signal.
