Abstract
Real-time X-ray dosimetry sensing in intraoperative radiation therapy (IORT). According to one aspect, a treatment head comprises at least one X-ray component configured to facilitate generation of therapeutic radiation in the X-ray wavelength range. A resilient balloon is disposed over the treatment head and configured for receiving therein a fluid to facilitate X-ray treatment of a tumor cavity. A plurality of X-ray sensing elements is disposed at a plurality of locations distributed on the interior or exterior of the resilient balloon and configured for sensing X-ray radiation emanating from the treatment head. A control system is provided that is responsive to data received from the X-ray sensing elements to determine a magnitude of X-ray radiation detected at each of the X-ray sensing elements.
