Abstract

A photoacoustic diagnostic apparatus having a light source, a probe which receives an acoustic wave generated when light is directed onto an object from a light source and which converts the acoustic wave into an electrical signal, a memory unit which records the electrical signal and a memory control unit which controls whether or not to cause the memory unit to record the electrical signal. The memory control unit controls the memory unit on the basis of a timing at which the probe receives an acoustic wave generated from a portion other than a light absorbing material inside an object.

First claim

The invention claimed is:

1. A photoacoustic diagnostic apparatus, comprising:
a light source;
a probe which receives an acoustic wave generated when an object is irradiated with light from said light source and which converts the acoustic wave into an electrical signal; and
a computer, comprising memory and at least one of a CPU and an MPU, cooperating to function as a memory unit which is configured to record the electrical signal on a recording medium, and
wherein said co…
