METHOD AND SYSTEM FOR REGISTERING ULTRASOUND AND COMPUTED TOMOGRAPHY IMAGES

摘要

A method for registering ultrasound (US) and computed tomography (CT) images, comprising: receiving US and CT images representative of a body portion comprising blood vessels and an initial approximate transform; enhancing the blood vessels in the US and CT images, thereby obtaining an enhanced US and CT images; creating a point-set for a given one of the enhanced US and CT images; determining a final transform between the point-set and the other one of the enhanced US and CT images using the initial transform; applying the final transform to a given one of the US and CT images to align together a coordinate system of the US image and a coordinate system of the CT image, thereby obtaining a transformed image; and outputting the transformed image.
