METHOD AND APPARATUS FOR CATHETER GUIDANCE USING A COMBINATION OF ULTRASOUND AND X-RAY IMAGING

摘要

An apparatus for tracking movement of a foreign object within a subject has an X-ray fluoroscopic system with an X-ray detector and an ultrasound system that has a probe with a position sensor. A display is configured to display a static X-ray image acquired by the X-ray fluoroscopic system and a real-time ultrasound image acquired by the ultrasound system. The X-ray image and the ultrasound image each display at least a portion of the foreign object and at least a portion of surrounding area. A tracking module is configured to track movement of the foreign object within the ultrasound image and the display is further configured to display an indication of the movement of the foreign object on the X-ray image

1. A method for positioning a guide wire within a subject during a procedure, the method comprising:
capturing and displaying a static X-ray image comprising at least a tip of a guide wire and a vascular tree pattern of vessels indicated by contrast; utilizing an ultrasound system to collect real-time live ultrasound images throughout at least a portion of the procedure; displaying the live ultrasound images comprising at least the tip of the guide wire and at least a portion of the vessels to show motion of the guide wire in real time on the live ultrasound images throughout at least the portion of the procedure; registering the static X-ray image with the live ultrasound images; identifying the guide wire on both the X-ray image and the ultrasound image; automatically detecting movement of the guide wire within the live ultrasound images throughout at least the portion of the procedure; and presenting, on the static X-ray image throughout at least the portion of the procedure, an indication of movement of the guide wire within the vascular tree pattern, wherein the indication of movement is based on the movement of the guide wire automatically detected within the life ultrasound images.
