摘要： In a photoacoustic measurement apparatus and a photoacoustic measurement system, blood flow information in a desired region can be generated using a photoacoustic image. A light source 13 emits measurement light. A probe 11 detects a photoacoustic wave generated in a subject after measurement light is emitted to the subject in each of the avascularized condition in which the subject is avascularized and the non-avascularized condition in which the subject is not avascularized. Photoacoustic image generation means 25 generates a photoacoustic image based on the detection signal of the photoacoustic wave. Blood flow information generation means 27 generates blood flow information based on the signal value of a photoacoustic image in a region of interest set in the photoacoustic image.
