Photoacoustic imaging method |
| 摘要 |
A photoacoustic imaging method comprises the steps of using modulated light of two different modulation frequencies to illuminate an object to be observed, so that an image of only a region of a specified depth within the object is obtained based on the difference between two photoacoustic signals separately detected by an acoustic sensor.
