Abstract:
1. A method for imaging tissue under examination, comprising: a source of illumination disposed upstream and emitting light directed onto the tissue for passage therethrough and for exit therefrom as downstream exiting light, an image detector disposed downstream of the tissue for receiving light, and for emitting signals derived from the received light, a processing unit coupled to the image detector for receiving emitted signals, for processing received signals, and for delivering processed data, the method being comprising the steps of: coupling the processing unit to and in command of the illumination source for triggering emission of at least one pulse of light lasting for a predetermined duration of time, operating a fast gate coupled to and under command of the processing unit and disposed upstream of the image detector, to open into a first open state and to close into a second closed state in predetermined synchronization with the at least one pulse of light for selectively permitting passage to the image detector of only ballistic photon rays pertaining to the exiting light, and operating the processing unit to derive an image from the signals received by the image detector.
