摘要： In a photoacoustic measurement apparatus and a photoacoustic measurement system, a region of interest useful for the evaluation of blood flow is set. A subject is avascularized while changing the avascularization pressure between the avascularized condition and the non-avascularized condition. A receiving circuit (21) receives a detection signal obtained by detecting a photoacoustic wave generated in the subject by emission of measurement light to the subject. Photoacoustic image generation means (25) generates a photoacoustic image based on the detection signal of the photoacoustic wave. Motion detection means (31) detects the motion of each of a plurality of control points set in each photoacoustic image based on photoacoustic images at a plurality of times. Region of interest setting means (32) sets a region of interest based on the motion detected at each control point. Blood flow information generation means (27) generates blood flow information based on the signal strength of the photoacoustic image in the region of interest.

摘要： The purpose of the invention is to find each component of a blood flow velocity using a simple process. In a secondary beam method, scanning is performed using Doppler measurement ultrasound beams (42) as primary beams, and Doppler measurement components are measured on the basis of the ultrasound waves received from the direction of each Doppler measurement ultrasound beam. Then, ultrasound waves forming secondary beams (58) at a direction that intersects the direction of the Doppler measurement ultrasound beams are sent and received, and the Doppler effect for the secondary beam direction component at the point of intersection of the Doppler measurement ultrasound beam (42) with the secondary beams (58) is measured. Furthermore, using the intersection point as the position for starting integration, an integration calculation based on the law of conservation of mass is performed along the route that intersects with the Doppler measurement ultrasound beams (42), and the component in the direction of the intersection route is found. The initial value for integration is the component in the direction of the intersection route of the integration start point (PA), and is found on the basis of the Doppler measurement component and the secondary beam direction component at the integration start point.

摘要： It becomes easy to check the position of an insert by suppressing the influence of artifacts in a photoacoustic image generation apparatus. An insertion needle (15) has a light guide member for guiding light emitted from a light source, a light emitting portion for emitting light guided by the light guide member, and a photoacoustic wave generating portion for generating photoacoustic waves caused by light emitted from the light emitting portion. Photoacoustic image generation means (24) generates a photoacoustic image based on the detection signal of the photoacoustic waves. Distal end candidate extraction means (29) extracts a distal end candidate region from the shallow side of the image based on the strength of the detection signal of the photoacoustic waves. Image output means (26) displays the extracted distal end candidate region on image display means (14).
