Electronic beam scanning for ultrasonic imaging

摘要: Abstract of the Disclosure A method producing cross-sectional images uses an ultrasonic imaging unit operating on pulse-echo principle and comprises a transducer system having stationary elongated array adjacent elements with trans-verse electrode segments one another at least side; successively cyclically selected groups are used to produce beam in response pulsed electric transmitter signals applied segments, also transmit into heterogeneous body, receive echoes reflected from discontinuity generate echo signal received echoes.
