Abstract
Disclosed herein is a multi-modal imaging methodology for creating patient-specific three-dimensional images of a breast volume, for use in the production of breast implants. In one aspect, a surface imaging technique may be used to create a three-dimensional model of an external shape of a patient, such as the external morphology of a breast. In one aspect, an internal imaging technique may be used to create a three-dimensional model of the internal shape of the thorax underneath the breast. The external and internal models may then be referenced to one another and a unified model may be created to generate a reliable, personalized model of breast volume.
Claims17
A method for designing an implant for a subject, comprising:
- generating an internal three-dimensional model of an internal anatomy of the subject from at least one internal image of the internal anatomy of the subject, the at least one internal image comprising at least one internal view of an anatomical landmark;
- generating an external three-dimensional model of a surface of the subject from at least one surface image of the surface of the subject, the at least one surface image comprising at least one external view of the anatomical landmark;
- registering the internal three-dimensional model to the external three-dimensional model with the anatomical landmark to create a unified three-dimensional model of the subject;
- identifying an internal anatomical geometry of the subject from the internal three- dimensional model and an external anatomical geometry of the subject from the external three- dimensional model;
- calculating an implant shape and volume based on a difference between the internal geometry and the external geometry in the unified three-dimensional model;
- and
- creating a three-dimensional model of an implant having the calculated implant shape and volume;
- wherein the implant is a breast implant, and wherein the at least one internal view comprises the pectoralis major.
A system for designing an implant for a subject, comprising a computing device comprising a non-transitory computer-readable medium with instructions stored thereon, which when executed by a processor perform steps comprising:
- generating an internal three-dimensional model of an internal anatomy of the subject from at least one internal image of the internal anatomy of the subject;
- generating an external three-dimensional model of a surface of the subject from at least one surface image of the subject;
- wherein the at least one surface image is generated by a method selected from the group consisting of a 3D scanner, stereoscopic imaging, millimeter-wave imaging, and infrared imaging:
- registering the internal three-dimensional model to the external three-dimensional model with an anatomical landmark present in the internal three-dimensional model and the external three-dimensional model to create a unified three-dimensional model of the subject;
- identifying an internal anatomical geometry of the subject from the internal three-dimensional model and an external anatomical geometry of the subject from the external three-dimensional model;
- calculating an implant shape and volume based on a difference between the internal geometry and the external geometry in the unified three-dimensional model;
- and creating a three-dimensional model from the of an implant having the calculated implant shape and volume.
