Computer Restoration of 2D Medical Diagnostic Signals with Noise Frequency Spectrum

摘要

In previous research articles of the authors interpolation of ECG signal was made [1-6]. The method used is the one from L. Aizenberg[1] for analytical continuation of finite functions. In connection with X-ray studies, CT scans and other application tasks require restoration of the Fourier spectrum, if its values are unknown at a certain interval. That task is to make interpolation of the spectrum in this interval. The article presents a calculation and experiment results, in a recovery of the spectrum of X-ray image by interpolation. Computing is done in MATLAB.
