The present invention relates to a method of correcting image data from the recordings of a sequence of measurements recorded in a time sequence by a medical diagnostic imaging system on an object under examination, at least a first image data set of i:he sequence relating to the object under examination before, and at least a second image data set of the sequence relating to the object under examination at and/or after the occurrence of a diagnostically relevant event, and in a first step, a first correction being made to the image data in that, by displacing the image contents in the depictions of the measuring sequence, the position of the object under examination in all the images is brought substantially into coincidence, in a second step, a second correction being made to the image data by an average image being formed from the first image data set corrected in the first step, and all the images of the first and second image data sets corrected in the first step being normalized, image element by image element, to the calculated average image and, in a third step, a third correction being made to the measured data, in that the value of an image element from a structurally uniform image region of at image of the first image data set corrected in the second step, or an average of image elements fromthis image region in the first image data set is subtracted from the values of all the image elements of this region in the first and second image data set. |
