The invention relates to the field of digital processing of X-ray images and can be used in digital subtraction angiography to compensate for impact of involuntary patient movement and movement of internal organs on image of the vascular system. The technical result of the claimed invention is the improvement of diagnostic value of subtraction angiographic images by eliminating artifacts caused by the motility of anatomical structures. Technical result is achieved by the that at the stage of digital images registration a search for characteristic details is performed for each image. According to the shift of the said details determine expectable shift of a patient organs. Then perform segmentation of image from the pre-contrast series in the region of homogenous warping ; for each region a geometrical transformation is calculated and corresponding geometrical transformations are performed for each region of a series of pre-contrast digital images. This means vessels visibility enhancement and treatment and diagnostic improvement.

A diagnostic drug and a diagnostic kit for autoimmune diseases including at least one of a polypeptide selected from an HMG-1 family, a polypeptide selected from an HMG-2 family, a fragment thereof which is reactable with an antibody of an autoimmune disease patient, and a method for detecting an antibody of an autoimmune disease patient using the same are provided.

A direct X-ray system for industrial radiography like non-destructive testing applications, and personal monitoring, being particularly less sensitive to pressure phenomena, has been disclosed, said system consisting of a direct X-ray black-and-white negative-working radiographic film material, comprised of a transparent support coated on at least one side thereof with a tabular grain emulsion layer, substantially free from spectrally sensitizing dyes, in which at least 50 percent of total grain projected area of all grains is accounted for by silver bromoiodide tabular grains having an iodide content of less than 5 mole %, based on silver, having an average aspect ratio of at least 2, and having a volume greater than 0.03 mum3, further characterized in that said tabular grain emulsion layer(s) comprise(s), in an amount of from 5 mg up to 100 mg per mole of coated silver bromoiodide at least one desensitizing agent having a hetero-aromatic part and an electron-withdrawing group and (2) disposed on opposite sides of the radiographic element, two intensifying screen sheets selected from the group consisting of lead, lead oxide, copper and steel, said screen sheets having been designed in order to emit electrons when exposed to X- or gamma-rays with an energy greater than or equal to 10 kVp.
