Abstract
The present teaching relates to surgical procedure assistance. In one example, a plurality of similarity measures are determined between a first set of positions and a plurality of second sets of positions, respectively. The first set of positions is obtained with respect to a plurality of sensors coupled with a patient in an image captured prior to a surgical procedure. The plurality of second sets of positions are obtained from the plurality of sensors and change in accordance with movement of the patient. A target lesion is segmented in the image captured prior to the surgical procedure to obtain a lesion display object. The lesion display object is duplicated to generate a plurality of lesion display objects. The plurality of lesion display objects are presented on a display screen so that a distance between the plurality of lesion display objects changes in accordance with the plurality of the similarity measures.
