RADIOACTIVE IMPLANT PLANNING SYSTEM AND PLACEMENT GUIDE SYSTEM

An implant planning system aids delivery of radiation to tumor sites of a patient. The system allows a user to test various combinations of virtual implants, each associated with a corresponding physical implant (e.g., a carrier with an embedded radioactive seed), and to view the dosage area of the virtual implants so that adjustments to the virtual implants may be made until a prescribed dose of radiation to a treatment area is achieved. A treatment plan developed based on the virtual implants may then be used in surgical implantation of the corresponding physical implants. For example, the implant configuration of the treatment plan may be projected onto a treatment surface of a patient, such as in a surgical room, so that physical implants may be placed according to the projected image of the virtual implants.
