Abstract: A device and method to diagnose an internal abnormality in a living subject by sensing a passively occurring electromagnetic radiation signal associated with the abnormality and inside an orifice of the subject. Diagnosis includes detection, imaging or identification of the abnormality. An instrument is used either to bring a sensor into the orifice or to transmit the signal to a sensor located outside of the orifice. An example of the instrument includes a prior art endoscope.

Abstract: A device and method are disclosed to non-invasively identify a lesion inside a region of living tissue. The region is exposed to medium infrared (MIR) radiation to preferentially heat the lesion The region is then scanned for black body radiation in a medium infrared waveband A lesion, being hotter than the surrounding tissue, is detected as domain of increased local emittance of MIR radiation Further scanning or heating in a second waveband is used to identify a particular class of lesions. The invention is particularly useful for early identification of malignant breast cancer.

Abstract: A device and method to non-invasively identify pathological skin lesions. The method and device detect and identify of different kinds of skin nevi, tumors, lesions and cancers (namely, melanoma) by combined analyses of visible and infra-red optical signals based on integral and spectral regimes for detection and imaging leading earlier warning and treatment of potentially dangerous conditions.
