Patent ID: 8774902

Claim:
A method for revealing an abnormality in live internal tissue of a living subject while exposing the subject to no potentially dangerous radiation or radioactive tracers of any kind, requiring no surgical removal of tissue, the method comprising the steps of: a) placing an instrument inside an orifice of the living subject, said instrument configured to provide at least an integral regime scan and spectral regime scan of target tissue; b) detecting the abnormality by sensing, via said instrument, a passively occurring electromagnetic radiation signal naturally emitted by the cells inside said orifice, said signal being associated with the abnormality; c) computing gradient temperature contrast of said target tissue to a normal tissue; d) estimating a temperature of said target tissue based on said temperature contrast; e) determining if said target tissue is abnormal based on a visual inspection of a visual image of said target tissue, said temperature contrast and said estimated temperature; f) if anomaly, measuring a spectrum of said naturally emitted passively occurring electromagnetic radiation signal, and d) identifying the abnormality based on a result of said measuring; wherein said measuring a spectrum includes investigating a contrast (C) in specific bands so as to identify a cancerous lesion and differentiate said cancerous lesion in the frequency domain, by use of the following formula: C (Δλ i )=[ R″c (Δλ i )− R′c (Δλ i )/ R″c (Δλ i )+ R′c (Δλ i )] where R′c is a background heat flow, R″c is a heat flow from said target tissue and Δλi is a specific range in the frequency band.
