    1. Perspectives of optical coherence tomography imaging and Raman spectroscopy in cancer diagnosis

      Perspectives of optical coherence tomography imaging and Raman spectroscopy in cancer diagnosis

      Biomedical optical imaging and optical spectroscopy are rapidly emerging as strong contenders for non-invasive optical biopsy. In biomedical imaging, Optical Coherence Tomography (OCT) is an established imaging modality for non-contact depth-resolved three-dimensional imaging with micrometer scale resolution. OCT provides label-free micro-structural morphological information of the tissue. Raman spectroscopy is a complementary tool for obtaining molecular-specific information for diagnosis. This article provides a brief overview of the underlying principles of OCT and Raman spectroscopy, their instrumentation with representative latest developments in cancer diagnosis.

    2. Optical, spectroscopic, and Doppler evaluation of "normal" and "abnormal" reflexology areas in lumbar vertebral pathology: a case study.

      Optical, spectroscopic, and Doppler evaluation of "normal" and "abnormal" reflexology areas in lumbar vertebral pathology: a case study.

      Scientific validation of reflexology requires an in-depth and noninvasive evaluation of “reflexology/reflex areas” in health and disease. The present paper reports the differential properties of “normal” and “abnormal” reflexology areas related to the lumbar vertebrae in a subject suffering from low back pain. The pathology is supported by radiological evidence. The reflexology target regions were clinically assessed with respect to colour and tenderness in response to finger pressure. Grey scale luminosity and pain intensity, as assessed by visual analogue scale scores, differentiated “normal” from “abnormal” skin. Skin swept source-optical coherence tomography recorded their structural differences. Infrared thermography revealed temperature ...
