Abstract: A system and method for examining or imaging brain functions of a subject includes a light source and a light detector located on the exterior surface of the subject's head. The light source introduces transcranially optical radiation into the brain of a subject, and the light detector detects radiation that has migrated in a brain region from the light source to the detector. The system also provides brain stimulation and evaluates the detected radiation to determine a brain cognitive function of the subject. One embodiment of the system can detect a brain disorder. Another embodiment of the system can detect “deceit.” In addition to the optical module, the system may include other optional modules such as an EEG module, an MEG module, a thermography module, a respiratory module, a skin conductivity module, and a blood pressure module.

Abstract: An optical examination technique employs an optical system for in vivo non-invasive transcranial examination of brain tissue of a subject. The optical system includes an optical module arranged for placement on the exterior of the head, a controller and a processor. The optical module includes an array of optical input ports and optical detection ports located in a selected geometrical pattern to provide a multiplicity of photon migration paths inside the biological tissue. Each optical input port is constructed to introduce into the examined tissue visible or infrared light emitted from a light source. Each optical detection port is constructed to provide light from the tissue to a light detector. The controller is constructed and arranged to activate one or several light sources and light detectors so that the light detector detects light that has migrated over at least one of the photon migration paths. The processor receives signals corresponding to the detected light and forms at least two data sets, a first of said data sets representing blood volume in the examined tissue region and a second of said data sets representing blood oxygenation of the examined tissue. The processor is arranged to correlate the first and second data sets to detect abnormal tissue in the examined tissue.

Abstract: An optical system for examination of biological tissue includes a light source, a light detector, optics and electronics. The light source generates a light beam, transmitted to the biological tissue, spaced apart from the source. The light detector is located away (i.e., in a non-contact position) from the examined biological tissue and is constructed to detect light that has migrated in the examined tissue. The electronics controls the light source and the light detector, and a system separates the reflected photons (e.g., directly reflected or scattered from the surface or superficial photons) from the photons that have migrated in the examined tissue. The system prevents detection of the “noise” photons by the light detector or, after detection, eliminates the “noise” photons in the detected optical data used for tissue examination.

Abstract: A spectroscopic system for quantifying in vivo concentration of an absorptive pigment in biological tissue includes an oscillator for generating a first carrier waveform of a first frequency on the order of 108 Hz, a light source for generating light of a selected wavelengths modulated by the carrier waveform, and a detector for detecting radiation that has migrated over photon migration paths in the tissue from an input port to a detection port spaced several centimeters apart. The wavelength is sensitive to concentration of an absorptive pigment present in the tissue. A phase detector compares the detected radiation with the introduced radiation and determines therefrom the phase shift of the detected radiation. A processor quantifies the concentration of the absorptive pigment by calculating a value of the absorption coefficient.

Abstract: A method of breast tissue examination using time-resolved spectroscopy includes the following steps. A support that includes an input port and an output port separated by a selected distance is positioned relative to the examined breast. Locations of the input and output ports are selected to examine a tissue region of the breast. Light pulses of a selected wavelength and duration less than a nanosecond are introduced into the breast tissue at the input port and detected over time at the detection port. Signals corresponding to photons of detected modified pulses are accumulated over time. Values of a scattering coefficient or an absorption coefficient of the examined breast tissue are calculated based on the shape of the modified pulses. The examined breast tissue is characterized based on the values of the scattering coefficient or the absorption coefficient. Absorbing or fluorescing contrast agents may be introduced into the examined tissue. This method may be used in conjunction with x-ray mammography, needle localization procedure or MRI mammography.

Abstract: The present invention utilizes differential measurement of radiation that migrated into two migration paths between two source-detector pairs placed on the head in a manner that each path is localized in a portion of one hemisphere of the brain. The present invention also provides various embodiments of spectrophotometer systems for in vivo examination of tissue of a human by measuring changes in electromagnetic radiation scattered and absorbed in a migration path in the tissue. Generally, the spectrophotometer systems comprise a light source for introducing the radiation into the tissue, a detector for detecting radiation that has migrated in the tissue, a processor for processing signals of the detected radiation to create processed data, and a system for determining physiological or pathophysiological changes in the tissue of interest. The present invention also provides for determining the metabolic condition of an aerobically stressed portion of tissue such as the muscle tissue of an exercising person.
