1. A system for spatial registration of an intravascular treatment source used for therapy on a patient comprising:
- a treatment structure for holding a treatment source, both of which are moveable through a vascular system;
a positioning device coupled to the treatment structure, said device being configured to enable establishing spatial position of the structure; and
an imaging device disposed to view a treatment area of the patient to provide image data for display of the treatment source disposed in the patient.

Abstract
A system and method for intravascular treatment planning and therapy on a patient. The system includes a structure for holding a treatment source, such as a radiation source, and also moving the treatment source through a patient'"'"'s vascular system using a positioning device which includes a component to establish the location relative to a particular reference position. An imaging device is also disposed in association with a vascular treatment area and the treatment source to register the resulting image information, enabling formation of three dimensional image in real time for use by a clinician.

23. A method of intravascular treatment of a patient, comprising the steps of:
-
providing a treatment energy source coupled to a positioning component;
positioning the treatment energy source in a vascular system using the positioning component which includes a coupling to a position sensor, thereby establishing a distance of travel of the treatment energy source in the vascular system;
registering image information characteristic of the treatment energy source to image information characteristic of at least a portion of the vascular system of the patient; and
generating in substantially real time, three dimensional registered image information for the treatment energy source and the vascular system of the patient. - View Dependent Claims (24, 25)
