Abstract
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.

1-20. (canceled)
A computer implemented method of collecting data for designing an implant to be implanted in a subject, the method comprising:
- obtaining computer readable image data including one or more images that in the aggregate represent a 3-dimensional image of a missing segment of tissue and at least some adjacent tissue;
- and
- rendering from the image data a 3-dimensional surface representation of the at least some adjacent tissue.
A method for obtaining data for determining a shape of a medical device to be implanted into a subject, the method comprising:
- obtaining by a machine of computer readable 3-dimensional image data of a defective portion of tissue in the subject and at least some adjacent tissue;
- identifying the defective portion in the 3-dimensional image data;
- and
- rendering the at least some adjacent tissue.
A system for collecting data for designing an implant to be implanted in a patient, the system comprising:
- a computer-readable medium having stored therein a 3-dimensional image data of a defective portion of tissue in the subject and at least some adjacent tissue;
- and
- a machine configured to render the at least some adjacent tissue.
