[Generation and processing of digital images in radiodiagnosis].
The paper describes universal principles of diagnostic imaging. The attention is focused particularly on digital image generation in medicine. The methodology of display visualization of measured data is discussed. The problems of spatial relation representation and visual perception of image brightness are mentioned. The methodological issues of digital image processing (DIP) are discussed, particularly the relation of DIP to the other related disciplines, fundamental tasks in DIP and classification of DIP operations from the computational viewpoint. The following examples of applying DIP operations in diagnostic radiology are overviewed: local contrast enhancement in digital image, spatial filtering, quantitative texture analysis, synthesis of the 3D pseudospatial image based on the 2D tomogram set, multimodal processing of medical images. New trends of application of DIP methods in diagnostic radiology are outlined: evaluation of the diagnostic efficiency of DIP operations by means of ROC analysis, construction of knowledge-based systems of DIP in medicine.
