HEYDAROVA, CH. A. EFENDIYEV, A.T. RAGIMOV This work is devoted to the questions of contrasting images obtained by magnetic resonance imaging. Contrast adjustment within certain limits, involving increase in contrast and its decrease considered in this research. The presented studies have shown that the physical processes occurring in a nuclear magnetic tomograph processes do not allow the adjustment of contrast to the necessary extent. In this regard, it is proposed to use the television method of adjusting the contrast – the gamma correction. The proposed method considered as a multi-step, andnumber of steps therein can vary quite widely, unlike convetional gamma correction methods. Moreover, gradation adjustment by the operator can acquire arbitrarily non-linear, this makes it possible to allocate the object of interest in the study area, thus contrasting them in a special way. Moreover, depending on the difference in luminance (steps) contrasting border areas acquire higher precision, i. e. precision correction is occured. Thus, the combination of tomograph and television system with gamma corrector will allow researchers to diagnose the disease more accurately.
