The use of a titanium body for manufacture of rotating anodes of diagnostic X-ray tubes is suggested. The results of metallographic analysis of a composite anode made of titanium, molybdenum, and tungsten are discussed. Titanium is demonstrated to be the optimal material of the anode body. Comparative analysis of temperature fields of two anodes made of titanium and molybdenum is presented. © 2011 Springer Science+Business Media, Inc.

An experimental comparative study of the efficiency of three methods for measurement of the resolution of digital radiographic systems is described. An algorithm for subpixel angular projection was constructed. This algorithm allows the resolution of X-ray camera and test object to be measured using a narrow slit and sharp edge. Test results obtained using various methods are compared. © 2011 Springer Science+Business Media, Inc.

Use of the Fluoro-ProGraph-RP digital fluorograph for tomosynthesis is described. Specific conditions for application are listed, and results of its functions are presented. In particular, calibration of a focal spot of X-ray generator is discussed, as well as elimination of optical distortions and experimental tests for marginal effects in the case of large objects. The tests performed in this work show that the Fluoro-ProGraph-RP fluorograph can be used in tomosynthesis. © 2014, Springer Science+Business Media New York.
