Abstract:
1. A method of producing images of infrared (IR) radiation of a patient, the method comprising the steps of: (a) providing an IR imaging camera configured to receive IR radiation from an array of optical elements (optels) in a field-of-view viewable by the IR imaging camera; (b) acquiring a plurality of frames of IR radiation from a patient positioned in the field-of-view, with each frame acquired during a corresponding frame sample interval, with each frame corresponding to the IR radiation acquired from the array of optels during its frame sample interval; (c) determining plural integrals of IR radiation received from the array, with each integral determined for the IR radiation received from the same optel in at least two frames; (d) mapping each integral to a color or a shade of gray; and (e) mapping the color or the shade of gray of each integral to a position in an image corresponding to the position of the corresponding optel in the field-of-view.
