摘要： For the purpose of noise correction for an x-ray flat-panel detector (2) it is firstly provided that in the dark image—without radiation impinging on the detector panel (4)—the noise is recorded for the subareas of an active area (8) and from this, subarea-specific correction factors are determined by means of which the respective signal value of the respective subarea is corrected in imaging operation. A dark area correction factor (DF1, DF2) is also determined in each case from the noise of two dark areas (6) that are spaced apart with respect to each other. In order to determine subarea-specific signal correction factors (SK), each of the DA correction factors (DF1, DF2) is weighted with a subarea-specific weighting factor (g1, g2), in particular a distance factor (a). By means of said measure improved noise correction is achieved.

摘要： A technique is provided for improving digital images by analysis of the sampling rate of the image data. The optimal sampling rate is determined, such as based on the point-spread function of the imaging system, and is compared to the actual pixel sampling rate. Based upon the comparison, the image may be shrunk or sub-sampled to provide the optimal sampling rate that allows for optimal image filtering while accounting for inherent variations in spatial resolution of the images.

摘要： An X-ray machine includes a radiation source and an image intensifier. A digital camera is downstream of the image intensifier and includes a pixel matrix, wherein the pixel matrix is switchable between a high and a low resolution. The image intensifier displays on an output screen, an image that is dependent on the incident X-radiation and that is picked up by the camera. Imaging behavior of the image intensifier, and thus the sharpness of the image displayed on the output screen, vary depending on the resolution set for the camera.
