VERFAHREN ZUR BILDFORMUNG EINES UNBESTIMMTEN MEDIUMS

摘要

A non-invasive medical imaging technique capable of evaluating, in situ, the oxygenation state of body tissues (2) (e.g., by measuring the spectral properties of heme proteins) is described. The disclosed technique employs a multi-wavelength collimated source (1) and a collimated receiver (6) and performs a positional and angular scan of the scattered radiation for each position of the incident beam. The resultant data is evaluated by employing imaging schemes which give differential weights to the contribution of various volume elements in the medium to the detector responses at various frequencies. These measurements yield physiological information while being, for example, an indicator of physiological stress caused by disease or trauma.
