<P>PROBLEM TO BE SOLVED: To efficiently detect the disconnection and deterioration of optical fibers in a photoacoustic imaging apparatus including a probe composed by arranging piezoelectric elements and the leading ends of optical fibers for propagating light. <P>SOLUTION: The photoacoustic imaging apparatus includes the probe 103 composed by arranging the piezoelectric elements 131 and the leading ends of the optical fibers 130 for propagating light. The apparatus is provided with a means for detecting a change in output voltage due to the pyroelectricity of the piezoelectric elements 131. <P>COPYRIGHT: (C)2012,JPO&INPIT |
