[A method for modernization of intraoral roengenography].
Experience in the use of PARDUS X-ray diagnostic apparatuses for intraoral roentgenography of maxillodental system is described. A method providing better uniformity of amplification in roentgenographic images of maxillodental system is suggested.
Equipment Design↗
[Dental microfocal radiology].
A technique for microfocal X-raying is proposed. This technique makes it possible to use screen-X-ray films. Exposure for aimed shot should not exceed 0.1 mAsec.

[A method for calculation of the absorbed dose].
The method suggested in this work uses spectral dependences of X-ray radiation intensity. The obtained theoretical dependences of attenuation factors coincide with the experimental values with an accuracy of 1-3%. The suggested technique makes it possible to determine the absorbed and exposure doses of radiation. It also provides determination of contrast of a shadow X-ray image.

[Portable microfocal radiographic devices for medical diagnosis].
The paper outlines two portable microfocal X-ray medical diagnostic devices which have a designing principle in common. The basic features of the devices are as follows: a thin long fight-path tube at whose end there is a massive or shooting target, a three-electrode electron gun, a private-line tungsten loop-shaped cathode, and a magnetic focusing system.
