Abstract
This optoacoustic imaging device is provided with: a light source part for irradiating an object to be inspected with light; an ultrasonic vibrator for detecting an acoustic wave generated from a subject to be detected in the object to be inspected which has absorbed the light emitted from the light source part; and a detecting part disposed in a probe body and including an acoustic lens disposed closer to the tip side of the probe body than the ultrasonic vibrator, wherein the acoustic lens is configured to have a light absorbance of 1-30% and a light reflectance of less than 85% with respect to light which has a wavelength band of 650-1000 nm and is emitted from the light source part.
Claims8
A photoacoustic imaging apparatus comprising:
- a light source portion that emits light to a test object;
- and
- a detecting portion arranged at a probe body, the detecting portion comprising an ultrasonic transducer and an acoustic lens, the ultrasonic transducer detecting an acoustic wave generated from a detection target in the test object when the detection target absorbs light emitted from the light source portion, the acoustic lens being arranged closer to a tip of the probe body than the ultrasonic transducer, wherein
- the acoustic lens is configured to have a light absorption ratio from 1 to 30% and a light reflectance of less than 85% in a wavelength region from 650 to 1000 nm of light emitted from the light source portion.
