摘要： In an ultrasonic imaging system including an array of ultrasonic oscillators, ultrasonic beams are electronically scanned by sequentially selecting a plurality of oscillator sets for beam transmission and reception. For one transmission of ultrasonic waves, at least two receiver oscillator sets having at least some oscillators in common are simultaneously selected, and the respective outputs from the oscillators in the at least two receiver oscillator sets are phase-adjusted so that echoes received by the at least two receiver oscillator sets effectively correspond to echoes substantially emanating from at least two respective different points on a depth level distanced from the plane of the oscillator array by a predetermined depth, whereby at least two signals and hence at least two successive scan lines relating to the echoes from those respective different points are produced. As a result, improved line resolution and rapid line acquisition can be obtained.

摘要： In a pulse Doppler flow speed meter in which ultrasonic wave pulses are transmitted repetitively at transmission intervals T and thereafter transmitted repetitively at transmission intervals (T+Ts), phases of reflected waves due to reflection of individual transmission pulses are measured sequentially to provide phase signals and the phase signals are subjected to frequency analysis to determine speed distributions, distributions of phase differences between phase signals corresponding to transmission pulses transmitted at the transmission intervals T and distributions of phase differences between phase signals corresponding to transmission pulses transmitted at the transmission intervals (T+Ts) are determined. A value of center of gravity of the former phase difference distributions and a value of center of gravity of the latter phase difference distributions are determined and then a phase difference between the two values of center of gravity is determined. Obtained from the phase difference are values of Doppler shift angle, according to which the former and latter phase difference distributions are shifted so as to be compensated for their aliasing.
