Title:
光音響イメージング装置およびその制御方法
Document Type and Number:
Japanese Patent JP5627360
Kind Code:
B2
Abstract:
A photoacoustic imaging apparatus is used that comprises a light source capable of irradiating light onto an object from a plurality of directions, a detector that detects acoustic waves generated by the object irradiated with light, a calculator that calculates object information from detected acoustic waves, and a generator that generates image data from the object information. The calculator calculates a plurality of object information pieces corresponding to irradiation in respective directions on the basis of acoustic waves at a time of irradiation of light at dissimilar timings from the plurality of directions. The generator selects, for each region and according to a predetermined criterion, image data of increased contrast in a case where a plurality of image data items on the object are generated on the basis of the plurality of object information pieces, and generates image data by combining the image data selected in each region.
