    • 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 volume (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.
    • 本发明涉及一种用于对浑浊介质内部进行成像的方法,装置和医学图像采集装置。 该方法包括以下步骤:在接收容积(5)内容纳混浊介质; 将来自照射光源的光耦合到所述接收容积(20)中; 通过将来自所述照射光源的光耦合到所述接收容积(25)中来检测从所述接收容积发出的光; 基于检测到的光(30)重建混浊介质的内部的图像。 本发明的目的是降低来自除了照射光源之外的光源的光对图像质量的影响。 根据本发明,该目的是通过以下步骤来实现的:该方法还包括以下步骤:当没有来自照射光源的光耦合到接收体积中时,在相对于混浊介质的至少一个位置处测量接收体内的光级 (10); 当没有来自照射光源的光通过使用光级指示器(15)耦合到接收容积中时,在相对于浑浊介质的至少一个位置处呈现关于接收体内的光级的信息。 根据本发明,装置和医学图像采集装置包括:光电检测器单元,用于当没有来自照射光源的光耦合到接收体积中时,检测从接收体积发出的光; 光级指示器,用于当根据本发明的方法将没有来自照射光源的光耦合到接收体中时,呈现与接收体内的光级有关的信息。
