Abstract: The invention relates to a method of localizing an object in a turbid medium. After measurement of the intensities for a plurality of light paths between the light sources and the detectors, the measured intensities are normalized. Subsequently, an image of the interior of the turbid medium is reconstructed on the basis of the measured intensities. In order to counteract artefacts in the reconstructed image, the combination includes a weighting factor which reduces the effect exerted on the reconstructed image by the measured intensities with a high noise factor in comparison with the effect exerted thereon by the measured intensities with a low noise factor.

Abstract: The invention relates to a method of localizing an object in a turbid medium. The invention also relates to a device for carrying out such a method. The method can be used in optical mammography during which a part of a breast of a female body is examined by means of light. To this end, the part of the breast is introduced into a holder of the device, said holder being provided with light sources and detectors. In order to realize an optical coupling between the light sources and the detectors and the breast, a calibration medium is introduced. After measurement of the intensities for a plurality of light paths between the light sources and the detectors, the measured intensity is normalized. In order to counteract artifacts which are caused by deviations of the optical properties of the calibration medium and the mean optical properties of the part of the breast, according to the invention the measured intensities are corrected prior to the reconstruction of the interior of the breast.

Abstract: The invention relates to a method of localizing an object in a turbid medium, utilizing an exponential function which determines the effect of an attenuation coefficient of a voxel of the turbid medium on an intensity of light transported through the turbid medium. In order to determine the estimated intensity variation on a photodetector, for each voxel the contribution to the intensity variation is determined by means of this exponential function. In order to reduce the required calculation time, this exponential function is approximated by a function which can be split into two orthogonal vectors. Consequently, the number of times that the value of an exponential function must be determined can be substantially reduced, resulting in a substantial reduction of the calculation time required for the reconstruction of an image of the interior of the turbid medium.
