ABSTRACT
The article presents the methods for formation of acoustic images for medical purposes; the process of their formation involves irradiation of the control object, registration of the scattered echo signals, their processing for focusing the image and transformation of summary echo signal. A strong response of the focused point by summing the signals from different points of the measurement aperture was obtained by focusing the echo signals.
KEYWORDS
ultrasound imaging, contrast resolution, the echo signal, a holographic system.
