Abstract
An apparatus according to the present invention includes a processor processing characteristic distribution information derived from an acoustic wave generated from an object and which indicates specific values at a plurality of positions inside the object, wherein the processor: sets a first position of interest; acquires first weight distribution information which is related to a plurality of positions including the first position of interest; and acquires a substitute value for a specific value at the first position of interest using the first weight distribution information, the specific value at the first position of interest, and a specific value at a position that differs from the first position of interest among the plurality of positions.
Claims18
An apparatus comprising:
- a light irradiating unit configured to irradiate an object with light;
- a receiving unit configured to output a signal in response to receiving an acoustic wave generated from the object irradiated with light;
- and
- a processor configured to acquire characteristic distribution information, which indicates specific values at a plurality of positions inside the object, using the signal,
- wherein the processor is configured to:
- set a first position of interest;
- acquire first weight distribution information which corresponds to the first position of interest and which is related to a plurality of positions including the first position of interest;
- and
- acquire a substitute value for a specific value at the first position of interest using the first weight distribution information, the specific value at the first position of interest, and a specific value at a position that differs from the first position of interest among the plurality of positions.
A method of processing using characteristic distribution information which is derived from an acoustic wave generated from an object irradiated with light and which indicates specific values at a plurality of positions inside the object, the acoustic wave being generated by an apparatus including a light irradiating unit, a receiving unit and a processor, the method comprising the steps of:
- setting a first position of interest;
- acquiring first weight distribution information which corresponds to the first position of interest and which is related to a plurality of positions including the first position of interest;
- and
- acquiring a substitute value for a specific value at the first position of interest using the first weight distribution information, the specific value at the first position of interest, and a specific value at a position that differs from the first position of interest.
