OBJECT INFORMATION ACQUIRING APPARATUS AND OBJECT INFORMATION ACQUIRING METHOD

摘要

This invention employs an object information acquiring apparatus including a probe for receiving, as a received signal, an acoustic wave which is generated within an object irradiated with light and propagates on an object surface, and a processor for generating object information, which is information based on an internal optical characteristic value of the object, by using intensity of the received signal. The processor corrects the intensity of the received signal by using the reflectance upon the acoustic wave entering the probe which is calculated based on the angle of the acoustic wave entering the probe, and on the acoustic impedance and acoustic velocity of the object and the probe.

1. An object information acquiring apparatus, comprising:
a probe configured to receive an acoustic wave which is generated by an object irradiated with light and output a time-series signal; and a processor configured to obtain object information for a voxel or pixel by using the time-series signal, wherein said processor is configured to obtain the object information for the voxel or the pixel without using an intensity of the time-series signal which is derived from the voxel or the pixel and which is obtained when an angle of the acoustic wave entering the probe exceeds an upper limit.
