    • An arrangement quantitatively determines the blood flow within blood vessels through which blood flows in a volume of a tissue defining a surface. Three-dimensional first image data of a first volume portion of the volume is detected and optical second image data is detected continuously in time of a first surface portion of the surface. A calibrating unit of the arrangement calibrates the relative value of the flow speed and/or the volumetric flow of the blood flowing through the blood vessels disposed directly below the first surface portion based on the absolute values of the flow speed and/or of the volumetric flow of the blood. An output unit outputs the absolute values of the flow speed and/or the volumetric flow of the blood flowing through the blood vessels arranged directly below the first surface portion.
    • 一种安排定量地确定血液中的血液流动,血液通过该血液在限定表面的组织的体积中流动。 检测体积的第一体积部分的三维第一图像数据,并且在表面的第一表面部分的时间连续地检测光学第二图像数据。 该装置的校准单元基于流速和/或体积的绝对值来校准流过设置在第一表面部分正下方的血管的血液的流速和/或体积流量的相对值 流血。 输出单元输出流过设置在第一表面部分正下方的血管的血液的流速和/或体积流量的绝对值。
