摘要： A phase adjustment circuit for use in an ultrasonic apparatus which respectively time-adjusts a plurality of received signals from an ultrasonic transducer array and sets wave fronts of the reflected waves from particular positions into an in-phase state and adds the in-phase signals, thereby obtaining a received beam. The received signals are mixed with phase-controlled reference signals. The low frequency component of the mixed wave is sequentially sampled and stored in a memory which is controlled by a clock signal of a predetermined period, and thereafter, the stored sampled signals are read out. Most of the necessary time adjustment results from the difference between the writing time and the reading time. The remaining micro time adjustment is performed by phase control of the reference signals.

摘要： A beam former method and an apparatus therefor in an ultrasonic imaging system, in which switching of delay elements is performed by means of delay switches in a section in which no ultrasonic wave transmission/reception is performed and switching noise generated in this section is stored as a noise signal into a memory. The stored noise signal is subtracted from a reception signal which is obtained through ultrasonic wave transmission/reception and which contains switching noise superimposed thereon to thereby obtain a reception signal from which the noise has been eliminated.

摘要： A frequency transfer type phase adjustment apparatus for frequency-transferring a plurality of reception signals derived from arrayed ultrasonic transducer elements into low frequency components by mixing these reception signals with a reference signal, and for applying delays to these low frequency components so as to be summed with each other, comprises small delay circuits for applying very short delays to the respective reception signals before being frequency-transferred; and a quantizing delay circuit for applying delays obtained by multiplying a delay time unit by an integer, to the respective reception signals after being frequency-transferred. A ratio of the delay time unit to one-cycle period of the reference signal is equal to an integer ratio. Phase shifters are inserted into either the output sides or the input sides of the mixers for the respective signal channels used for the frequency transfer operation. These phase shifters are capable of selectable phase shift amounts from a finite number of phase shift amounts which have been prepared for compensating phase differences in the delayed reception signals.
