System and Method For Dynamic Device Tracking Using Medical Imaging Systems

摘要

A system and method are provided for generating images that track a position and shape of a medical device within a subject. The method includes acquiring image data from a subject along at least two disparate view angles, each view angle including a deformable medical device arranged in the subject. The method also includes receiving images reconstructed from the image data and exploring a search space to compare the images with a dynamic three-dimensional (3D) model at least using a deformation parameter to determine a position and shape of the deformable medical device within the subject. The method further includes displaying an image of the subject and deformable medical device arranged within the subject based on the position and shape of the deformable medical device within the subject.

1. A method for generating images that track a position and shape of a deformable medical device within a subject, the method comprising:
(i) receiving image data acquired from the subject along at least two disparate view angles, each view angle including a deformable medical device arranged in the subject; (ii) accessing a three-dimensional (3D) model including the deformable medical device that includes a deformation parameter for the deformable medical device; (iii) exploring a search space including the deformation parameter to match the image data with the 3D model within a predetermined tolerance to determine a position and shape of the deformable medical device; and (iv) using the image data and the position and shape of the deformable medical device determined in (iii), displaying an image of the deformable medical device arranged within the subject.
