Abstract:
1. A method for directly monitoring in-situ both the balloon/cavity and the radioactive source in brachytherapy treatment comprising: A) introducing a high intensity non-liquid radioactive source and a relatively low intensity liquid radiation source into a patient: B) simultaneously acquiring separate images of: 1) said high intensity non-liquid radioactive source emitting photon radiation at one particular photon energy as it is moved in a tumor volume during brachytherapy; and 2) said relatively low intensity liquid radiation source produced by either an injected radiopharmaceutical rendering cancerous tissue visible or by a radioactive solution filling a balloon surgically implanted into the cavity formed by the surgical resection of a tumor; said low intensity liquid radiation source emitting photons at a different energy than the non-liquid radioactive source; C) registering the two thus acquired images of two different photon energies; and D) displaying said images.
