Embodiment Construction
[0059] figure 1 An embodiment of the method according to the present invention is schematically shown. In step 5, the turbid medium is contained in the receiver. Next, according to the present invention, in step 10, when no light from the illuminating light source is coupled into the receiver, the light level in the receiver is measured at at least one position relative to the turbid medium. Then, in step 15, information about the light level of at least one position in the receiver relative to the turbid medium when no light from the illuminating light source is coupled into the receiver is presented. This information is presented through the use of light level indicators and can be presented in a variety of ways. One way is to use an auditory signal to inform the operator of the device according to the method of the present invention whether the light level in the receiver is acceptable when no light from the illuminating light source is coupled into the receiver. The auditory...

The invention relates to a method, device, and medical image acquisition device for imaging an interior of a turbid medium. The method comprises the following steps: accommodation of the turbid medium inside a receiving volume (5); - coupling light from an irradiation light source into the receiving volume (20); detecting light emanating from the receiving volume as a result of coupling light from the irradiation light source into the receiving volume (25); reconstructing an image of an interior of the turbid medium on the basis of detected light (30). It is an object of the invention to reduce the effect of light from a light source other than the irradiation light source on image quality. According to the invention this object is realized in that the method further comprises the following steps: measuring the light level inside the receiving volume at at least one position relative to the turbid medium when no light from the irradiation light source is coupled into the receiving vo lume (10); presenting information relating to the light level inside the receiving volume at at least one position relative to the turbid medium when no light from the irradiation light source is coupled into the receiving volume through use of a light level indicator (15). According to the invention the device and medical image acquisition device comprise: - a photodetector unit for detecting light emanating from the receiving volume when no light from the irradiation light source is coupled into the receiving volume; a light level indicator for presenting information relating to the light level inside the receiving volume when no light from the irradiation light source is coupled into the receiving volume according to the method according to the invention.
