Annular array design and logarithmic processing for ultrasonic imaging

Annular array design and logarithmic processing for ultrasonic imaging

The design of an annular array for electronic focal scanning depends upon the frequency of operation, a suitable limit of lateral resolution and the number and size of the elements of the array. The frequency is determined by considering (1) the frequency dependent attenuation caused by the tissues...

description The design of an annular array for electronic focal scanning depends upon the frequency of operation, a suitable limit of lateral resolution and the number and size of the elements of the array. The frequency is determined by considering (1) the frequency dependent attenuation caused by the tissues of interest, (2) the limiting characteristic of the receiver and (3) its equivalent input noise. The array size is determined by (1) the operating frequency, (2) the method of scanning and (3) a suitable limit of lateral resolution. Unusual resolution capability is realized with only five elements, equally spaced in the array, and with logarithmic signal processing in the receiver.
