Abstract

Systems and methods are provided for designing and producing custom-fit prosthesis. According to one embodiment, a mold is produced from which a custom-fit implant may be directly manufactured. Medical image data representing surrounding portions of a patient'"'"'s anatomy to be repaired by surgical implantation of the custom-fit implant are received. Then, three-dimensional surface reconstruction is performed based on the medical image data. Next, the custom-fit implant is designed based on the three-dimensional surface reconstruction and a two-part mold is created with a void in the shape of the custom-fit implant by subtracting a representation of the custom-fit implant from a representation of a mold. Finally, the two-part mold is output from which the custom-fit implant may be directly manufactured.

Claims

1. A method a producing a mold from which a custom-fit implant may be directly manufactured, the method comprising:

receiving medical image data representing surrounding portions of a patient'"'"'s anatomy to be repaired by surgical implantation of the custom-fit implant;

performing three-dimensional surface reconstruction based on the medical image data;

designing the custom-fit implant based on the three-dimensional surface reconstruction;

creating a two-part mold with a void in the shape of the custom-fit implant by subtracting a representation of the custom-fit implant from a representation of a mold; and

outputting the two-part mold from which the custom-fit implant may be directly manufactured.
