Abstract
A computer implemented method for determining the 3-dimensional shape of an implant to be implanted into a subject includes obtaining a computer readable image including a defective portion and a non-defective portion of tissue in the subject, superimposing on the image a shape to span the defective portion, and determining the 3-dimensional shape of the implant based on the shape that spans the defective portion.
Claims10
A method for generating a three-dimensional implant shape of a medical device comprising:
- segmenting data in a volumetric image of a patient wherein the volumetric image comprises target tissue of a region of interest of the patient wherein the target tissue comprises a defective portion and a non-defective portion;
- rendering a surface of the patient image from the segmented data wherein the surface comprises the defective and non-defective portions;
- superimposing by warping or best-fitting a deformable template onto the surface of the patient image to span the defective portion;
- producing a three-dimensional shape from the deformable template that fits the defective portion of the target tissue;
- producing a three-dimensional implant shape from computer-readable data representing the deformable template, wherein the three-dimensional shape seats in the defect and fits relative to the surrounding anatomy of the patient other than the target tissue, and
- forming the three-dimensional implant shape into an implant.
