Patient monitor
First Claim
1. A patient monitor comprising:
- a 3D position determination module operable to determine measurements indicative of shape and location of at least part of a patient;
a clock module operable to associate measurements indicative of the shape and location of at least part of a patient determined by the 3D position determination module with timing data, a model generation module operable to partition the shape and location and timing data into a plurality of groups of data each associated with different portions of the breathing cycle and utilize the portioned data to generate a plurality of component analysis models of the variation in shape and location of the at least part of a patient during the respective different portions of the breathing cycle; and
a comparison module operable to utilize shape and location and timing data and a plurality of component analysis models generated by the model generation module to identify breathing which differs from that occurring in the images used to generate the component analysis models.

Abstract
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. If abnormal breathing or patient movement is detected the comparison module sends a signal to a treatment apparatus to interrupt treatment until normal breathing resumes or alternatively to a mechanical couch to reposition the patient to account for the detected movement.
