Embodiment Construction

[0031] Figure 1 schematically shows an embodiment of a device for imaging the interior of a turbid medium. The device 1 comprises: a light source 5, which may comprise a plurality of separate sub-light sources 5a, 5b, 5c, 5d, 5e and 5f; a photodetector unit 10; an image reconstruction unit 12 for detecting incoming light to reconstruct an image of the interior of the turbid medium 55; the measurement volume 15 is bounded by a wall 20 comprising a plurality of entry locations for light 25a and a plurality of exit locations for light 25b; and light Conduits 30a and 30b, coupled to said entry and exit locations for light. The device 1 also comprises a selection unit 35 for coupling the light source 5 to a plurality of selected entrance locations in the wall 20 for the light 25a. The light source 5 is coupled to the selection unit 35 with an input light guide 40 . The selection unit 35 comprises an exit element 45 comprising a plurality of exit positions 45a for delivering light...

Abstract

The invention relates to a device for imaging an interior of a turbid medium. Said device (1) comprises a measurement volume (15) for accommodating the turbid medium. Said measurement volume (15) comprises a number of sources capable of communicating light, said sources comprising a preferred source, capable of communicating preferred light and a further source, capable of communicating further light. Said device (1) further comprises a detection unit capable of detecting composed light comprising a preferred component comprising at least a part of the preferred light and a further component comprising at least a part of the further light. The device is adapted such that the negative effect said further component in the composed light may have on detecting the preferred component also present in the composed light is counteracted. According to the invention this object is realized in that the preferred source and the further source are located such that a path followed by the preferred component from the preferred source to the detector unit and a path followed by the further component from the further source to the detector unit are substantially the same.

Description

technical field [0001] The invention relates to a device for imaging the interior of a turbid medium, said container comprising a measurement volume for containing a turbid medium, said measurement volume comprising a plurality of sources capable of transmitting light, said sources comprising a preferred source capable of delivering preferred light and a secondary source capable of delivering further light, the device further comprising a detection unit capable of detecting a composite light comprising a preferred component comprising at least a portion of the preferred light and A secondary component comprising at least a portion of the secondary light. The term "light" is understood to cover the entire electromagnetic spectrum. [0002] The invention also relates to a medical image acquisition device comprising the device. [0003] The invention also relates to a selection unit for coupling a light generator to said preferred source and for selecting said preferred source ...
