Patent Images
1. A method for non-contact cardiac assessment of a subject, the method comprising:
- capturing images of the subject from at least two synchronized independent imaging devices spaced equidistant from the subject and positioned such that each imaging device captures an image of the subject different from other imaging devices;
extracting spectral components of the captured images;
analyzing the extracted spectral components;
identifying a signal in the extracted spectral components corresponding to cardiac information; and
extracting the signal in the extracted spectral components corresponding to the cardiac information.

Abstract
A system and method are provided for non-contact cardiac assessment of a subject. Images of the subject are captured from at least two synchronized independent imaging devices spaced equidistant from the subject and positioned such that each imaging device captures an image of the subject different from other imaging devices. Spectral components of the captured images are extracted. The extracted spectral components are analyzed. A signal corresponding to cardiac information is identified in the extracted spectral components. The identified signal corresponding to the cardiac information is extracted from the extracted spectral components.

9. A system for non-contact cardiac assessment of a subject, the system comprising:
-
at least two imaging devices configured to individually capture images of the subject, the imaging devices being spaced equidistant from the subject and positioned such that each imaging device captures an image of the subject different from other imaging devices; a data acquisition card in electrical communication with the at least two imaging devices; and at least one computer in electrical communication with the at least two imaging devices and configured to; receive captured images from the at least two imaging devices; extract spectral components of the captured images; analyze the extracted spectral components; identify a signal in the extracted spectral components corresponding to cardiac information; and extract the signal in the extracted spectral components corresponding to the cardiac information, wherein trigger signals generated by the data acquisition card cause images to be captured simultaneously by the at least two imaging devices and sent to the computer. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
