Radiation-activated Fiducial Markers for Organ Tracking

摘要

A system may include transmission of an activation beam to one or more non-radioactive elements disposed in a patient volume, wherein the elements become radioactive in response to the activation beam, detection of radiation emitted by the one or more now-radioactive elements, determination of respective locations of the one or more now-radioactive elements based on the detected radiation, and transmission of a treatment beam to the patient volume based on the respective locations.
