Document Type and Number:
Japanese Patent JP6685413
Kind Code:
B2
Abstract:
Provided is a photoacoustic measurement device including: an ultrasound image generation unit that generates an ultrasound image on the basis of a detection signal of reflected ultrasonic waves generated by the transmission of ultrasonic waves; a puncture needle detection unit that detects a length direction of a puncture needle on the basis of the ultrasound image; and a controller that controls a steering direction of a sample gate which is a Doppler measurement target on the basis of the length direction of the puncture needle such that an angle θ formed between a straight line extending in the length direction of the puncture needle and a straight line extending in the steering direction of the sample gate satisfies 0°≤θ<90°.
