PLANNING AN IMPLANTATION OF A CARDIAC IMPLANT

摘要

The present invention relates to a medical imaging system (10) for planning an implantation of a cardiac implant (42), comprising: a receiving unit (12) for receiving a plurality of three-dimensional (3D) cardiac images (14, 14′) showing different conditions of a heart (32) during a cardiac cycle; a segmentation unit (22) for segmenting within the plurality of 3D cardiac images (14, 14′) a target implant region (38) and a locally adjacent region (40) that could interfere with the cardiac implant (42); a simulation unit (24) for simulating the implantation of the cardiac implant (42) within the target implant region (40) in at least two of the plurality of 3D cardiac images (14, 14′); a collision evaluation unit (26) for evaluating an overlap (46) of the simulated cardiac implant (42) with the segmented locally adjacent region (40) in at least two of the plurality of 3D cardiac images (14, 14′); and a feedback unit (28) for providing feedback information to a user concerning the evaluated overlap (46).

1. A medical imaging system for planning an implantation of a cardiac implant, comprising:
a receiving unit for receiving a plurality of three-dimensional (3D) cardiac images showing different conditions of a heart during a cardiac cycle; a segmentation unit for segmenting within the plurality of 3D cardiac images a target implant region and a locally adjacent region that could interfere with the cardiac implant, wherein the target implant region is a part of a left ventricular outflow tract and the locally adjacent region is a part of a mitral valve; a simulation unit for simulating the implantation of the cardiac implant within the target implant region in at least two of the plurality of 3D cardiac images; a collision evaluation unit for evaluating an overlap of the simulated cardiac implant with the segmented locally adjacent region in at least two of the plurality of 3D cardiac images; and a feedback unit for providing feedback information to a user concerning the evaluated overlap.
