Assessment of complex cardiac anomaly with multi-slice CT and development of stereolithographical cardiac model

通过测量多层螺旋CT（MSCT）三维图像信息的心室容积，术前模拟显示了较高的有效性。采用立体光刻技术制作的刚性环氧树脂心脏畸形模型，解剖再现性好，对临床实习医生的教育和培训效果良好。用软聚氨酯树脂制作的心脏模型在模拟心脏手术、模拟切割等方面有进一步的应用前景。

Preoperative simulation by multi-slice CT (MSCT) showed high efficacy by measuring the ventricular volume of three-dimensional image information obtained from MSCT. Complex cardiac anomalies model that was created by the rigid epoxy resins using stereolithography technology showed highly anatomical reproducibility and the high efficacy has been shown to education and training of student doctors, in a patie nt explanation. The heart model produced by soft urethane resin suggested further possible applications to surgical simulation such as suturing and incision.
