摘要
The invention relates to a method and a device for increasing contrast in medical images generated by an imaging system featuring an x-ray source and a detector. The detector detects x-rays of the x-ray source and converts image signals from the x-rays. The image signals are transferred to a control and processing unit for processing. Deconvolution of the image signals is carried out by application of an inverse modulation transfer function modified by a regularization. At least a volume image can be reconstructed from the deconvolved image signals.
