ABSTRACT
Realization of the system of ultrasonic scanning of optically opaque media has been considered. The image formation model is presented, which served as a basis for the proposed block diagram of an ultrasound scanner. Separate units of the scanner and the software part, realized on the basis of calculations in the graphic adapters of the computer have been described. The ultrasonic scanner is designed for creating a portable mobile device with reduced energy consumption for medical and industrial purposes.
KEYWORDS
coherent system, echoscopy, formation of images, spatial and contrast resolution.
