Abstract

An ultrasound diagnostic device includes: a probe including plural elements that generate and transmit ultrasound waves and receive ultrasound waves reflected from an inspection target; a transmission unit that transmits ultrasound waves from the plural elements so as to transmit an ultrasound beam by forming a transmission focus in a first direction set in advance; and a second reception focusing unit that performs reception focusing for each reception signal received by each element of the probe according to reflection on a path in a second direction other than the first direction, among transmission wave paths of the ultrasound beam transmitted into the inspection target by the transmission unit.

Dependent claims

An ultrasound diagnostic device, comprising:

a probe including a plurality of elements that generate and transmit ultrasound waves and receive ultrasound waves reflected from an inspection target;
a transmission unit that transmits ultrasound waves from each of two or more different openings among the plurality of elements of the probe in a predetermined direction, wherein the transmission is performed so as to form a transmission focus for each of the two or more different openings respectively;
a memory;
and
a processor coupled with the memory, wherein the processor is configured to:
perform a plurality of first reception focusings, wherein each of the plurality of first reception focusing is performed in a first direction by using each of the two or more different openings respectively, wherein each of the first directions:
(i) passes through a common reflection point and each of the transmission focuses, and (ii) is inclined by an angle with respect to the predetermined direction, and
determine a direction of a needle based on a result of the first reception focusing.

5 more elements

An ultrasound diagnostic method, comprising:

transmitting ultrasound waves from each of two or more different openings among a plurality of elements of a probe so as to transmit an ultrasound beam by forming a transmission focus in a predetermined direction, wherein the transmission is performed so as to form a transmission focus for each of the two or more different openings respectively, the prove including the plurality of elements that generate and transmit ultrasound waves and receive the ultrasound waves reflected from an inspection target;
and
performing a plurality of first reception focusings, wherein each of the plurality of first reception focusing is performed in first directions by using each of the two or more different openings respectively, wherein each of the first directions:
(i) passes through a common reflection point and each of the transmission focuses, and (ii) is inclined by an angle with respect to the predetermined direction;
and
determining a direction of a needle based on a result of the first reception focusing.
