Abstract
In a photoacoustic measurement apparatus and a photoacoustic measurement system, it is possible to generate blood flow information using a photoacoustic image without requiring a separate tourniquet. A light source emits measurement light. A probe 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 unit generates a photoacoustic image based on the detection signal of the photoacoustic wave. Blood flow information generation unit generates blood flow information based on the signal value of a photoacoustic image in a region of interest set in the photoacoustic image. The avascularization of the subject is performed by pressing the probe against the subject.
