ULTRASOUND DIAGNOSTIC DEVICE, METHOD FOR GENERATING ACOUSTIC RAY SIGNAL OF ULTRASOUND DIAGNOSTIC DEVICE, AND PROGRAM FOR GENERATING ACOUSTIC RAY SIGNAL OF ULTRASOUND DIAGNOSTIC DEVICE

摘要

An ultrasound beam is transmitted to an inspection target by determining an opening of a positive phase and an opening of a negative phase corresponding to the opening of the positive phase in advance and inverting the phases with a group of a predetermined number of elements of a probe as each opening, and an ultrasound echo signal generated by interaction between the ultrasound beam and the inspection target is received through the plural elements of the probe. Then, two or more pieces of element data including receiving time information in each element, which are generated by receiving ultrasound echo signals generated for at least two or more overlapping target regions, are stored, and an acoustic ray signal in one scanning line is generated by overlapping the stored element data based on the receiving time information in each element.

1. An ultrasound diagnostic device, comprising:
a probe including a plurality of elements for generating ultrasound waves and receiving ultrasound waves reflected from an inspection target; a transmission unit that transmits ultrasound waves from the plurality of elements such that an ultrasound beam is transmitted to the inspection target by determining a group of a predetermined number of elements of the probe as openings, determining in advance an opening of a positive phase and an opening of a negative phase corresponding to the opening of the positive phase and inverting phases thereof; a receiving unit that receives an ultrasound echo signal generated by interaction between the ultrasound beam and the inspection target, through the plurality of elements of the probe; an element data storage unit that stores two or more sets of element data including receiving time information in each element, the two or more sets of element data being generated by transmitting the ultrasound beam from openings having different phases and having different elements at centers, in each of at least two or more overlapping target regions in the inspection target using the transmission unit, and receiving the ultrasound echo signal generated for each of the at least two or more overlapping target regions in the inspection target by the ultrasound beam, using the receiving unit; and a generation unit that generates an acoustic ray signal in one scanning line by overlapping the element data stored in the element data storage unit.
