Abstract

Multidimensional images are often used for the most convenient representation of the processes carrying out in the studied object. However, sometimes, especially in such areas as medical diagnostics or related ones, it is required to estimate quickly simultaneously several aspects of the observed process, and certain part of multidimensional image must be observed in details without influence of several excessive signal distribution along some dimensions. The acousto-optic method based on Bragg diffraction has been proposed for this problem solution which provides fast and automatic (controlled by software) way of multidimensional switching to its selective part or several parts. Especially this method is convenient in electrocardiography where signal processing produces such pictures as 3D mapping images or signal wavelet transform images. Information losses which appear due to this method application, have been estimated, and the ways of the method optimization from the point of view of maximum signal-to-noise ratio providing, have been proposed.
