Publication number: 20240082604Abstract: A method monitors radiation incidence onto an object being prepared for and/or undergoing radiation delivery. The monitoring method includes: emitting a light field onto a surface of an object being prepared for and/or undergoing radiation delivery, the light field at least substantially corresponding to radiation incidence of the radiation delivery; monitoring the light field being reflected from the surface of the object; and processing the monitored light field to determine the radiation incidence of the radiation delivery relative to the object at least partially based on the monitored light field.Type: ApplicationFiled: July 17, 2023Publication date: March 14, 2024Applicant: Vision RT LimitedInventors: Adrian Roger William BARRETT, Gideon Matthew HALE, Benjamin James WAGHORN

Publication number: 20240065651Abstract: Disclosed herein are embodiments of a monitoring system for use with a medical apparatus to monitor the position of a patient. The monitoring system can include at least one visual sensor providing visual data, at least one processing unit configured to generate, based on the visual data, one or more views; and at least one display for displaying the one or more generated views.Type: ApplicationFiled: August 24, 2023Publication date: February 29, 2024Inventors: Adrian Roger William BARRETT, Benjamin James WAGHORN

Patent number: 10828512Abstract: Some embodiments are directed to a monitoring system for monitoring the positioning of a patient relative to a treatment apparatus operable to deliver radiation along a radiation path. A model generation module is arranged to generate a model of a surface of a patient being monitored. A comparison module determines a transformation required to match the generated model to the stored model target surface. An offset determination module then utilizes the transformation and data indicative of a current position of a treatment apparatus to determine an offset value indicative of the offset of the surface of a patient relative to an axis corresponding to a determined current radiation path for radiation generated by the treatment apparatus applied to a patient. If the offset value exceeds a threshold, a warning may be generated or treatment may be halted.Type: GrantFiled: June 7, 2018Date of Patent: November 10, 2020Assignee: Vision RT LimitedInventors: Ivan Daniel Meir, Adrian Roger William Barrett

Publication number: 20200184625Abstract: A method of identifying portions of a model of a surface of a patient which can be used to identify to position of a patient is provided. A pre-existing model of the surface of a patient is utilised to generate simulated images of the projection of patterns of light onto the surface of the patient. The simulated images are then processed to generate a further model of the surface. Any differences between the model generated by processing the simulated images and the original model surface identifies portions of the surface which cannot be reliably modelled and hence portions of a surface which should not be used to monitor the positioning of a patient. The invention has particular application for identifying the reliability and accuracy of generated models of the surface of a patient used for monitoring and positioning a patient undergoing radiotherapy.Type: ApplicationFiled: August 7, 2018Publication date: June 11, 2020Applicant: VISION RT LIMITEDInventors: Ivan Daniel MEIR, Adrian Roger William BARRETT
