Computed tomography
A systematic presentation of computed (computational) tomography is given - a modern method of biomedical and technical diagnostics. The description and mathematical models of X-ray, emission (radionuclide), nuclear-magnetic resonance, doppler, radiation and ultrasonic tomography are described. Much attention is paid to mathematical methods of processing tomographic information.

Signals: conditioning, detection and processing
The foundations of the theory of discrete signals and systems are described. Methods for spectral analysis and filtering of discrete signals, algorithms for the synthesis of discrete filters, the effect of quantization effects and the finite accuracy of calculations on the operation of digital devices are considered. Modulation methods used to transmit digital information are described. Adaptive filters and multi-rate signal processing are discussed. Introductory lectures are devoted to the basics of signal analysis and the theory of analog systems. The material is outlined so as to clearly demonstrate the nature of the algorithms, their interrelationship and application areas. Theoretical information is accompanied by examples of implementation of the discussed algorithms with the help of the MATLAB system.
