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.
Claims24
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 the plurality of elements so as to form a plurality of ultrasound beams that converge at a single transmission focus and diverge from the single transmission focus, wherein the single transmission focus is associated with a predetermined direction;
- a memory;
- and
- a processor coupled with the memory, wherein the processor is configured
- to perform first reception focusing for each reception signal received by each element of the probe according to reflection in a reception focusing direction that is different from the predetermined direction, the reception focusing direction being a direction that passes through the transmission focus and is inclined by an angle with respect to the predetermined direction, and
- to determine a direction of a needle based on a result of the first reception focusing.
An ultrasound diagnostic method, comprising:
- transmitting ultrasound waves from a plurality of elements of a probe so as to form a plurality of ultrasound beams that converge at a single transmission focus and diverge from the single transmission focus, the probe including the plurality of elements that generate and transmit ultrasound waves and receive ultrasound waves reflected from an inspection target;
- and wherein the single transmission focus is associated with a predetermined direction;
- performing first reception focusing for each reception signal received by each element of the probe according to reflection in a reception focusing direction that is different from the predetermined direction, the reception focusing direction being a direction that passes through the transmission focus and 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.
A non-transitory storage medium storing an ultrasound diagnostic program that causes a computer to execute processing comprising:
- controlling transmission of ultrasound waves from a plurality of elements of a probe so as to form a plurality of ultrasound beams that converge at a single transmission focus and diverge from the single transmission focus, the probe including the plurality of elements that generate and transmit ultrasound waves and receive ultrasound waves reflected from an inspection target;
- and wherein the single transmission focus is associated with a predetermined direction;
- performing first reception focusing for each reception signal received by each element of the probe according to reflection in a reception focusing direction that is different from
- the predetermined direction, the reception focusing direction being a direction that passes through the transmission focus and 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.
