Publication number: 20240123260Abstract: The disclosed calibration method includes a calibration phantom positioned on an adjustable table on the surface of a mechanical couch, with the phantom's centre at an estimated location for the iso-centre of a radio therapy treatment apparatus. The calibration phantom is then irradiated using the apparatus, and the relative location of the center of the calibration phantom and the iso-centre of the apparatus is determined by analyzing images of the irradiation of the calibration phantom. The calibration phantom is then repositioned by the mechanical couch applying an offset corresponding to the determined relative location of the centre of the calibration phantom and the iso-centre of the apparatus to the calibration phantom. Images of the relocated calibration phantom are obtained, to which the offset has been applied, and the obtained images are processed to set the co-ordinate system of a stereoscopic camera system relative to the iso-centre of the apparatus.Type: ApplicationFiled: December 18, 2023Publication date: April 18, 2024Inventors: Ivan Meir, Martin Allen, Gideon Hale, Norman Smith, Robert Howe

Publication number: 20230293908Abstract: Images obtained by a camera system (10) arranged to obtain images of a patient (20) undergoing radio-therapy are processed by a modeling unit (56,58) which generates a model of the surface of a patient (20) being monitored. Additionally the patient monitoring system processes image data not utilized to generate a model of the surface of a patient being monitored to determine further information concerning the treatment of the patient(20). Such additional data can comprise data identifying the relative location of the patient and a treatment apparatus (16). This can be facilitated by providing a number or retro-reflective markers (30-40) on a treatment apparatus (16) and a mechanical couch (18) used to position the patient (20) relative to the treatment apparatus (16) and monitoring the presence and location of the markers in the portions of the images obtained by the stereoscopic camera (10).Type: ApplicationFiled: March 17, 2023Publication date: September 21, 2023Applicant: VISION RT LIMITEDInventors: Ivan MEIR, Kathryn COOPER, Norman SMITH, Gideon HALE, Martin ALLEN

Patent number: 9736465Abstract: An exemplary embodiment of a 3D camera system for a patient positioning and monitoring system is described. In the system a pair of image detectors are provided where the image detectors are each associated with a heater thermally connected to conducting pads provided at the periphery of the image detectors. The heaters and conducting pads act to contain the image detectors in a substantially constant temperature micro climate thereby preventing external temperature variations from causing the relative positions of the image detectors to change so as to record portions of images as different pixels and hence reduce the consistency with which the identification of matching portions of images obtained by the image detectors can be utilized to determine the 3D positions of imaged objects.Type: GrantFiled: April 25, 2013Date of Patent: August 15, 2017Assignee: VISION RT LIMITEDInventors: Peter Hanson, Gideon Hale
