<P>PROBLEM TO BE SOLVED: To provide a display data obtaining apparatus capable of, in photoacoustic tomography, reducing a fluctuation in sensitivity which depends on location for image reconstruction even in a limited measurement condition in which a photoacoustic wave generated in the entire subject cannot be obtained in a sufficient range. <P>SOLUTION: The display data obtaining apparatus includes: an acoustic wave obtaining unit for obtaining an acoustic wave generated from the subject irradiated with pulsed light; a first data deriving unit for deriving first data exhibiting an optical characteristic distribution of the subject based on the obtained signal obtained by the acoustic wave detecting unit; a memory for storing spatial sensitivity distribution data specific to the display data obtaining apparatus; and a second data deriving unit for deriving second data exhibiting the optical characteristic distribution of the subject using the first data and the spatial sensitivity distribution data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
