Device for the measurement of optically excited biological information for non-invasive diagnosis in vivo and in situ

摘要

The invention relates to a device for the measurement of optically excited biological information for the targeted position-defined and volume-defined, regional and interregional continuous non-invasive spectroscopic and electrical diagnosis of microcirculation, metabolism and bio-periodic sequences in vivo and in situ, by the application of a combined device measuring electrically and optoelectronically, consisting of emitter components in the visible and infrared region, photoreceiver components and electrodes. The invention can be applied in biomedical diagnosis, especially of the brain, but also in heart, liver and muscle diagnosis. The electrode (electrodes) and the detector for receiving the non-ionising light transmitted locally at the same wavelength and in the same location sequentially with different intensity, scattered back sequentially at different wavelengths or wavelength ranges, are arranged directly at or else close to the point of entry of the light, and in the same plane. The invention enables, on the one hand, both the complete elimination of undesired information from tissue layers which lie in front of or behind the region to be examined or measured, but also the elimination of undesired information from the region to be measured, for example the blood volume and, on the other hand, a combined electro-optical and electrical reference measurement of optically excited biological...
