The article discusses current state and development of one of the methods of X-ray research of internal structure of objects having different origin − computer micro-tomography (μCT). Computer micro-tomography mainly differs from conventional X-ray tomography in that here a microfocus X-ray tube with spot diameter of X-ray emission region of а few dozens or units of micrometers is used as X-ray source. In the present work, methods for increasing the output power of microfocus tubes with a shooting-type anode are proposed and investigated, the problems of precision focusing of electron beam are solved, research is conducted to create a high-voltage power supply for a microfocus tube and an X-ray detector. A significant part
of the work is devoted to the development of software for controlling the installation of micro-tomography, X-ray image processing and three-dimensional images reconstruction.

Key words: microfocus x-ray tube, electron-optical scheme, high-voltage power supply, x-ray detector, x-ray images.
