A system and method for the prevention of restenosis use a source of radiation to treat the blood vessel. An intravascular ultrasound imaging system (12) generates images of a treatment volume from within the blood vessel. A computer based treatment planner (20) acquires the images from the imaging system (12), and reconstructs a three-dimensional image of the treatment volume. From a dose prescription (28), the treatment planner (20) calculates which optimize the dose, and also registers the dose with images of the treatment volume. A voice recognition unit (36) allows medical personnel to provide voice commands for operating the system. The treatment planner (20) and imaging system (12) may be placed within a cath-lab, and enables the treatment plan to be dynamically changed based on patient specific information. A catheter guide (220) comprising markers (224, 226, 228, 225) allows medical personnel to determine the precise orientation of the imaging transducer, and location of the transducer along a length of the catheter guide (220). |
