Classification: CPC A | IPC A

Claim 0:
1. An object information acquiring method by using a spectroscopic photoacoustic imaging apparatus including a multi-wavelength light source, a transducer, and a scanning unit of the transducer, the method comprising:
dividing a whole region for which object information is to be acquired into a plurality of segmented regions to be scanned at least a plurality of times in association with a plurality of wavelengths of a plurality of pulsed lights from the multi-wavelength light source;
scheduling a scanning sequence including information in association with a scanning order of the plurality of segmented regions and a switching timing of a wavelength of an irradiation pulsed light from the multi-wavelength light source;
moving the transducer with respect to an object to scan the selected segmented region during a period of time for light irradiation with the pulsed light in the selected wavelength based on the scanning sequence;
receiving an acoustic wave signal with the transducer which is configured to obtain an electrical signal in association with the acoustic wave signal;
and
processing the electrical signal to acquire object information in association with the plurality of wavelengths of a plurality of pulsed lights,
wherein moving the transducer is performed such that the wavelength of the pulsed light is to be switched in a period of time when the transducer scans within one of the segmented regions or in a period of time when the transducer moves inter-region between the segmented regions.
