Patent number: 9028422Abstract: 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: February 12, 2009Date of Patent: May 12, 2015Assignee: Vision RT LimitedInventors: Ivan Daniel Meir, Norman Ronald Smith, Anthony Christopher Ruto
