摘要： Modern image processing systems for the postprocessing of X-ray images require a large number of input parameters and take a great deal of time. So that calculations do not need to be made sequentially for different sets of input parameters, parallel processors are used, in which the same image processing program is executed in each case, but with different input parameters in each case. A large number of processed X-ray images is thus obtained, which in particular can also be displayed simultaneously. From the multiple processed x-ray images, a repeated postprocessing of a processed x-ray image can take place by mixing.

摘要： X-ray diagnostic apparatus is disclosed having a video camera, at least one image memory, a differential stage to produce substraction images by forming the difference between a stored video signal and a video signal chronologically following the former signal, an evaluation circuit for the time evaluation of changes in the subtraction images, and a video monitor. The evaluation circuit includes a time memory for storing information about the chronological flow of the radiographic contrast medium. The evaluation circuit also includes an additional circuit that repeatedly scans the information stored in the time memory and reproduces only those of the image points on the monitor whose information meet a specified criterion. The value of this criterion is increased step-by-step.

摘要： In a method for correcting the image errors arising during an x-ray diagnostic measurement from the memory effect of a radiation-sensitive structure, particularly in the form of a photodiode array, of a solid-state detector which receiving the x-rays, given a change in the operating mode with a change of the radiation dose, a correction image is determined that is subtracted from the detector image obtained from the solid-state detector. For determining the correction image, at least one image signal supplied by the solid-state detector substantially immediately before or after the change in the operating mode, and thus the change of the radiation dose, is registered, this being subsequently weighted with at least one decay curve measured substantially synchronously with the pick-up of at least the image signal supplied immediately before the change, and substantially corresponding to the chronological decay behavior of the electrical charge in the radiation-sensitive structure of the solid-state detector of the image signal.
