ULTRASOUND DIAGNOSTIC APPARATUS, SIGNAL PROCESSING METHOD FOR ULTRASOUND DIAGNOSTIC APPARATUS, AND RECORDING MEDIUM

摘要

An object of the present invention is to provide an ultrasound diagnostic apparatus, a signal processing method, and a recording medium which are capable of eliminating a ghost signal with a small number of data when correcting element data by superimposing a plurality of element data, obtaining a high quality ultrasound image while preventing a decrease in the frame rate, and reducing the capacity of a memory. Information on a transmission frequency of an ultrasonic beam is acquired, and second element data is generated using a plurality of first element data on the basis of the acquired information on a transmission frequency.

主权项

1. An ultrasound diagnostic apparatus configured to inspect an inspection object using an ultrasonic beam, the apparatus comprising:
a probe having a plurality of elements arranged therein, the probe being configured to transmit the ultrasonic beam and receive an ultrasonic echo reflected by the inspection object, and to output an analog element signal according to the received ultrasonic echo; a transmitter configured to cause the probe to transmit the ultrasonic beam a plurality of times using at least two of the plurality of elements as transmission elements so as to form a predetermined transmission focus point; a receiver configured to receive analog element signals output by at least two of the plurality of elements that, as reception elements, have received an ultrasonic echo corresponding to individual transmission of the ultrasonic beam and to perform a predetermined process; an analog-to-digital converter configured to analog-to-digital convert the analog element signals processed by the receiver into first element data formed by a digital element signal; a data processor configured to generate second element data corresponding to any one of a plurality of first element data from the plurality of first element data; and a frequency information acquiring unit configured to acquire information on a transmission frequency of the ultrasonic beam transmitted from the probe; wherein the data processor generates the second element data using the plurality of first element data on the basis of the information on a transmission frequency acquired by the frequency information acquiring unit.
