Producing a three-dimensional model of an implant
Determining a shape of a medical device to be implanted into a subject produces an image including a defective portion and a non-defective portion of a surface of a tissue of interest included in the subject. The tissue of interest is segmented within the image. A template, representing a normative shape of an external anatomical surface of the tissue of interest, is superimposed to span the defective portion. An external shape of an implant, is determined as a function of respective shapes of the defective portion as seen in the template, for repairing the defective portion.
1. A computer implemented method of obtaining data for determining a three-dimensional shape of a medical device, the method comprising:
rendering a computer-generated three-dimensional representation of a target tissue from computer readable image data of the target tissue wherein the target tissue comprises two portions, a portion with a defect and a portion without a defect;
identifying anatomical landmarks on the computer-generated three-dimensional representation of the target tissue;
superimposing onto the rendered computer-generated three-dimensional representation of the target tissue a three-dimensional template to span the defective portion;
deforming the three-dimensional template to match the identified anatomical landmarks to determine the three-dimensional shape of the medical device.
2. The method as set forth in claim 1 , wherein the three-dimensional image data is obtained from image slices of the target tissue.
3. The method as set forth in claim 1 , wherein the three-dimensional image data is obtained as one or more voxels of the target tissue.
4. The method of claim 1 , wherein the medical device is an implant to be implanted in a subject.
5. The method of claim 1 , further comprising fabricating the 3-dimensional shape of the medical device.
6. The method of claim 1 , wherein deforming the three-dimensional template to match the identified anatomical landmarks to determine the three-dimensional shape of the medical device comprises determining the three-dimensional shape of the medical device based on the deformed template that spans the defective portion.
7. The method of claim 1 , wherein the anatomical landmarks are present on an external surface of the non-defective portion.
8. The method of claim 1 , further comprising generating the computer-readable image data of the target tissue.
9. The method of claim 8 , further comprising fabricating the 3-dimensional shape of the medical device.
