Patent number: 11147478Abstract: A patient monitor is disclosed for detecting patient movement or abnormal breathing. Images of a patient are obtained by a stereoscopic camera. These images are then processed by a 3D position determination module which determines measurements indicative of positions of at least part of a patient. The obtained measurements are then passed to a model generation module which generates a breathing model of the variation in position of the at least part of a patient during a breathing cycle. Subsequently abnormal breathing or patient movement can be detected by processing further images obtained by the stereoscopic camera to determine more measurements indicative of positions of at least part of a patient. These measurements are then compared with a stored breathing model by a comparison module.Type: GrantFiled: November 20, 2018Date of Patent: October 19, 2021Assignee: VISION RT LIMITEDInventors: Ivan Daniel Meir, Norman Ronald Smith, Anthony Christopher Ruto

Patent number: 8135201Abstract: Three camera rigs are connected by wiring to a computer. The computer is also connected to a treatment apparatus. A mechanical couch is provided as part of the treatment apparatus such that under the control of the computer the relative positions of the mechanical couch and the treatment apparatus may be varied. The camera rigs obtain video images of a patient lying on the mechanical couch the computer processes these images to generate a three-dimensional model of the surface of the patient which is utilized to position the patient relative to the treatment apparatus.Type: GrantFiled: January 10, 2011Date of Patent: March 13, 2012Assignee: Vision RT LimitedInventors: Norman Ronald Smith, Ivan Daniel Meir, Gideon Matthew Hale, Robert Edward Howe

Patent number: 7348974Abstract: An image processing system (1-5) is provided which obtains images of a patient (8) from multiple view points and which then generates positioning instructions for a mechanical couch (7) to vary the position of a patient. A number of techniques are disclosed in order to calibrate the image processing system so as to enable the image processing system to identify the iso center of radiation beams generated by a treatment apparatus (6). Techniques for processing generated 3 dimensional models to monitor a patient's breathing are also disclosed.Type: GrantFiled: September 23, 2005Date of Patent: March 25, 2008Assignee: Vision RT LimitedInventors: Norman Ronald Smith, Ivan Daniel Meir
