DYNAMIC DATA NORMALIZATION FOR COMPARISON AND QUANTITATIVE DETERMINATION OF PERFUSION

摘要

1. Device (42) for dynamic normalization of data for comparison and quantitative determination of perfusion, comprising a processing element configured to implement a method of dynamic normalization of data for comparison and quantitative determination of perfusion, wherein the processing element is configured to determine (20) the total volumetric flow rate or the amount of contrast medium in the blood vessel, and the processing element is configured to normalize (34) the perfusion data based on definiteness total volume flow in a blood vessel and the amount of contrast medium in a blood sosude.2. The device according to claim 1, further comprising an imaging element (55); wherein the imaging element (55) is configured to visually provide the user with at least one of the first normalized perfusion x-ray image data during the first image acquisition and the second normalized perfusion x-ray image data in the second image acquisition. 3. The device according to claim 1 or 2, further comprising an x-ray source (46) and an x-ray detector (44), wherein the object (48) can be placed between the x-ray source (46) and the x-ray detector (44), and wherein the x-ray source (46) and an X-ray detector (44) is operatively connected to obtain X-ray image data, in particular, X-ray image perfusion data of interest to an object region (48) .4. Method (10) for dynamic normalization of data for comparison and quantitative determination of perfusion, comprising the steps of determining
