[Bi-dimensional correction of x-ray images].

The frequency and contrast characteristics of the unit of the shadow image formation point to a material weakening of the high-frequency components in the spectrum of spatial frequencies already during the formation of the X-ray image. To compensate for this weakening that also takes place in other subassemblies of the television X-ray installation the introduction of an aperture corrector is necessary. As such a corrector in transmitting an image of little mobile objects a bidimensional aperture corrector set up on the transmitting television tube can be effectively used.

[Television medical endoscopes].

The paper considers the present stage of development and ways of improving TV endoscopes for medicine. It has been shown that the most promising are the TV endoscopes which have sequential colour-separated transmission circuit and include impulse R, G, B light sources. The light is transferred through fibre optical conduit and matrices installed at the distal end of the endoscope. Digital converters convert the colour-separated image signals into simultaneous ones. This circuit makes it possible to avoid using expensive and complex equipment in manufacture of fibre optics. It provides a suitable for diagnosis image quality which can be additionally improved by electronic treatment of the image signal.

[Methods and equipment for processing x-ray films by x-ray television].

A review of television methods used for processing the X-ray films shows that in the future the technique that combines television and roentgen will allow more precise diagnose in accordance to X-ray patterns on the basis of such processes as harmonization, subtraction, artificial colour painting to emphasize the details of the organs under study, and with application of automatic measurement of geometric parameters of the organ image.
