Abstract
A device elucidates reaction dynamics of photoreactive compounds present in a region of interest (ROI) of a tissue, the ROI being submitted to a controllably-varying and spatially homogenous magnetic field. The device includes at least one electrical coil or magnet for externally applying a magnetic field to the ROI. The device further includes light sources for probing the ROI with a probe optical beam and for illuminating the ROI with an optical beam having a wavelength and power level suitable for activating the photoreactive compounds. Collectors are also provided to collect the light emitted from various photoluminescence mechanisms that occur in the optically-activated ROI when the probe beam is incident on it and then to detect the collected light over predetermined wavelength bands. Finally, a computer is used to analyze the detected light for assessing the effects of the external magnetic field applied to the ROI.
