Fash fluorescence imaging device for diffuse optical tomography

A method for imaging an interior of a turbid medium (25) comprising the following steps:

• a) emission of excitation light from a light source (5), with the excitation light chosen such that it causes fluorescent emission in a fluorescent agent in the turbid medium (25);
• b) optically coupling the light source (5) to the receiving volume (20) for irradiating the receiving volume (20) with excitation light from the light source (5) from an entrance position for light (35a);
• c) detection of fluorescence light emanating from the receiving volume (20) as a result of the irradiation of the turbid medium (25) with excitation light from the light source (5),
• characterized in that
• the step of optically coupling the light source (5) to the receiving volume (20) comprises optically coupling the light source (5) to the receiving volume (20) for irradiating the receiving volume (20) with excitation light from the light source (5) from multiple entrance positions for light (35a) simultaneously.

A medical image acquisition device comprising:

• a) a receiving volume (20) for accommodating a turbid medium (25);
• b) a light source (5) for emitting excitation light, with the excitation light chosen such that it causes fluorescent emission in a fluorescent agent in the turbid medium (25);
• c) coupling means for optically coupling the light source (5) to the receiving volume (20), with the coupling means comprising an entrance position for light from which to irradiate the receiving volume (20);
• d) a photodetector unit (15) for detecting fluorescence light emanating from the receiving volume (20) as a result of the irradiation of the turbid medium (25) with excitation light from the light source (5)
• characterized in that
• the device is arranged to simultaneously couple excitation light from the light source (5) into the receiving volume (20) from multiple entrance positions for light relative to the turbid medium (25).
