摘要： An ultrasound system for planning a surgical implantation of a prosthetic aortic valve produces three dimensional images of the aortic root region of a patient. An electronic model of an aortic root is accessed and fitted to the aortic root in a three dimensional ultrasound image. Preferably the aortic root model exhibits closed contour cross-sections which are fitted to the endothelial lining of the aortic root in the ultrasound image. A medial axis of the fitted model is identified and radii measured from the medical axis to the border of the fitted model. The radii are joined to identify a surface forming a mesh model fitted to the aortic root anatomy of the patient. The shape and dimensions of the fitted model may be used to fabricate a custom prosthetic valve for aortic valve replacement.

摘要翻译： 用于规划假体主动脉瓣的手术植入的超声系统产生患者的主动脉根部区域的三维图像。 主动脉根部的电子模型在三维超声图像中被访问并适合于主动脉根部。 优选地，主动脉根部模型显示封闭的轮廓横截面，其被配合到超声图像中主动脉根部的内皮衬里。 识别拟合模型的中轴，并从医学轴线到拟合模型的边界测量半径。 连接半径以识别形成拟合到患者的主动脉根解剖结构的网格模型的表面。 拟合模型的形状和尺寸可用于制造用于主动脉瓣置换的定制假体瓣膜。
