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: 10861193Abstract: A calibration sheet is located at a first position where its surface substantially corresponds to the expected position of a patient surface lying on a mechanical couch during treatment. Images of the calibration sheet are obtained and processed to ascertain relative locations and orientations of the image detectors obtaining the images and optical distortion parameters indicative of optical distortions present in the obtained images of the calibration sheet. The calibration sheet is then re-located to a known position relative to the iso-centre of the treatment apparatus and images of the re-located calibration sheet are obtained and processed to determine a transform corresponding to the relocation of the calibration sheet from the first position to the iso-centre of the treatment apparatus. Data indicative of optical distortions present in the images and data indicative of the locations and orientations of the image detectors relative to the iso-centre of the treatment apparatus are stored.Type: GrantFiled: September 29, 2015Date of Patent: December 8, 2020Assignee: VISION RT LTD.Inventors: Edward Mead, Ivan Meir

Patent number: 9420254Abstract: A patient monitoring system can include stereoscopic cameras connected to a computer which includes a 3D position determination module operable to process stereoscopic images of a patient to identify 3D positions of a plurality of points on the surface of an imaged patient. A target model store can store a target model including data identifying 3D positions of a set of vertices of a triangulated 3D wire mesh model and connectivity indicative of connections between vertices. A matching module can identify the triangles in a target model surface stored in the target model store closest to points identified by the 3D position determination module and calculate a rigid transformation which minimizes point to plane distances between the identified points and the planes containing the triangles of the target model surface identified as being closest to those points.Type: GrantFiled: April 17, 2013Date of Patent: August 16, 2016Assignee: VISION RT LIMITEDInventor: Ivan Meir
