Abstract:
1. A method of monitoring a regional lung function of a person, the method including the steps of: a) projecting a pattern of radiation onto at least a portion of the person for monitoring; b) recording at a first instant in time first image data from a video camera disposed at a first viewpoint toward said portion of the person, said first image data representing at least a portion of said projected pattern of radiation on the portion of the person, said first image data being representative of a three dimensional configuration of said portion of the person at said first instant in time; c) recording at a second instant in time second image data from said video camera disposed at said first viewpoint toward said portion of the person, said second, image data representing at least a portion of said projected pattern of radiation on the portion of the person, said second image data being representative of a three dimensional configuration of said portion of the person at said second instant in time; and d) processing said first and second image data to generate differential data representative of a change in volume of said portion of the person between the first and second instants in time to determine the regional lung function of the person.
