The purpose of this study is to develop computer simulation program which realize the preoperative anatomical fitting test of a ventricular assist device (VAD) for each patient. Using the CT images, the three-dimensional (3D) surface of the thoracic cavity was constructed on the computer. The surfaces of the VAD in STL format was superimposed on that of thorax to examine anatomical compatibility of the VAD. As a result, display time of 51396.8±383.7ms and RAM usage of 7.852±0.151 GB (n=5) are required to construct the 3D image for the CT images of 439 slices (Fig.1). It was suggested that the performance of the newly developed program is enough to test anatomical fitting of the VAD.
