Method and system for dynamic pulmonary trunk modeling in computed tomography and magnetic resonance imaging

An apparatus for generating a pulmonary trunk model from 4D cardiac image data, comprising:

• means for receiving 4D cardiac image data comprising a plurality of frames, each frame comprising volumetric image data;
• means for detecting bounding boxes in the frames of the 4D cardiac image data;
• means for detecting anatomic landmarks in the frames of the 4D cardiac image data based on the detected bounding boxes;
• means for detecting ribs of a pulmonary artery in the frames of the 4D cardiac image data based on the detected anatomic landmarks;
• and
• means for generating a dynamic pulmonary trunk model by fitting a physiological pulmonary trunk model to the frames of the 4D cardiac image data based on the detected ribs and anatomic landmarks.

A computer readable medium encoded with computer executable instructions for generating a pulmonary trunk model from 4D cardiac image data, the computer executable instructions defining steps comprising:

• receiving 4D cardiac image data comprising a plurality of frames, each frame comprising volumetric image data;
• detecting bounding boxes in the frames of the 4D cardiac image data;
• detecting anatomic landmarks in the frames of the 4D cardiac image data based on the detected bounding boxes;
• detecting ribs of a pulmonary artery in the frames of the 4D cardiac image data based on the detected anatomic landmarks;
• and
• generating a dynamic pulmonary trunk model by fitting a physiological pulmonary trunk model to the frames of the 4D cardiac image data based on the detected ribs and anatomic landmarks.
