REGISTRATION OF ULTRASOUND DATA WITH PRE-ACQUIRED IMAGE

摘要

PROBLEM TO BE SOLVED: To provide a system and a method for constructing a a three-dimensional model from multiple ultrasonic images.

SOLUTION: The system and the method for imaging a target in a patient's body use a pre-acquired image of the target and a catheter having a position sensor and an ultrasonic imaging sensor. The catheter is placed in the patient's body and positional information of a part of the catheter in the body of the patient is determined by using the position sensor. The catheter is used for generating the ultrasonic image of the target by the ultrasonic imaging sensor. The positional information for all pixels of the ultrasonic image of the target is determined by using an image processor and the pre-acquired image is registered with the ultrasonic image. The registered pre-acquired image and the ultrasonic image are displayed by using a display.
