DISPLACEMENT DETECTION IN OPTICAL TOMOGRAPHY SYSTEMS

摘要

The invention relates to a method (1) for imaging an interior of a turbid medium comprising the following steps: a) accommodation (3) of the turbid medium in a receiving volume comprising an entrance position for light and an exit position for light; b) irradiation (5) of the turbid medium with light from a light source using an entrance position for light; c) detection (10) of light emanating from the receiving volume as a result of the irradiation of the turbid medium using a photodetector unit using an exit position for light; d) detection (15, 17) of an out of bounds displacement of the turbid medium using light emanating from the receiving volume. To this end the invention proposes a number of ways to detect an out of bounds displacement of the turbid medium based on comparing at least two signals relating to light emanating from the receiving volume and a single exit position. The invention also relates to a device (45) for imaging an interior of a turbid medium (90) and a medical image acquisition device (105) both employing the method. According to the invention the device (45) for imaging an interior of a turbid medium (90) and the medical image acquisition device are adapted such that they further comprise displacement detection means according to the method and its embodiments according to the invention.
