Abstract
A device and an agent for performing imaging in a deep part with high sensitivity and high resolution are to be provided. A photoacoustic measurement device (photoacoustic imaging device) performs light irradiation on an inspection area of a subject to which a photoacoustic agent generating an acoustic signal by causing phase change from a solid phase or a liquid phase to a gas phase by the light irradiation is administered, while the irradiated energy amount is increased, and detects the acoustic signal generated in the inspection area due to the light irradiation to form an imaged image of the inspection area based on the detected acoustic signal.
Claims11
A photoacoustic measurement device which irradiates an inspection area of a subject with light to form an photoacoustic image of the inspection area, the device comprising:
- a light irradiation unit that irradiates the inspection area with light to which an agent generating an acoustic signal by phase change due to light irradiation is administered;
- a controller that controls the light irradiation unit to intermittently increase a light energy amount irradiated from the light irradiation unit;
- an acoustic signal detector that detects the acoustic signal generated in the inspection area by the light irradiation;
- and
- an image processor that forms an photoacoustic image of the inspection area based on the detected acoustic signal.
