Publication number: 20150078647Abstract: A computer-implemented method of implant detection includes receiving a three-dimensional (3D) image of an anatomy portion of a patient from computed tomography (CT) projections of the patient in an image processing computing system. A cluster of voxels forming an implant candidate is identified on a CT slice of the 3D image and the identified implant candidate is compared with artifacts of implants from an implant database stored in a memory of the computing system. A best-fit implant is selected from the implant database and a graphical image of the best-fit implant is overlaid on the CT slice on a display of the computing system.Type: ApplicationFiled: November 17, 2014Publication date: March 19, 2015Inventors: Patrick A. HELM, Shuanghe SHI
