Abstract
The present teaching relates to surgical procedure assistance. In one example, a first volume of air inside a lung is obtained based on a first image of the lung captured prior to a surgical procedure. The lung has a first shape on the first image. A second volume of air deflated from the lung is determined based on a second image of the lung captured during the surgical procedure. A second shape of the lung is estimated based on the first shape of the lung and the first air volume inside the lung and second volume of air deflated from the lung. A surgical plan is updated based on the estimated second shape of the lung.
