Method for reducing image disturbances caused by reconstructed defective pixels in direct radiography. An adaptive reconstruction kernel taking up to four main and diagonal, defect-free sub-kernel directions into account is composed for each defective image pixel. The defective pixels impacted image is real-time corrected by statistical filtering or by a weighed directional convolution of kernel-associated replacement values, calculated by means of an advanced multi-parabolic reconstruction algorithm, for each contributing sub-kernel direction based on 5 x 5 pixels neighborhood image data readily accessible via a predetermined AMP kernels image-offsets structure. |
