SUBJECT INFORMATION OBTAINING APPARATUS, SUBJECT INFORMATION OBTAINING METHOD, AND PROGRAM

摘要

When a processing is carried out by using a Frequency-Domain Interferometry (FDI) method and an adaptive signal processing, a part where a continuity between adjacent scanning lines is scarce may occur. A subject information obtaining apparatus according to an aspect of the present invention includes a plurality of conversion elements configured to convert an elastic wave from a subject into a plurality of reception signals, a delay and sum unit configured to perform a delay and sum process by using the plurality of reception signals and output a plurality of scanning line signals, a scanning line synthesis unit configured to add the plurality of scanning line signals between adjacent scanning lines and output a plurality of synthesis scanning line signals, and an FDI adaptive processing unit configured to perform a frequency domain interferometry and an adaptive signal processing by using the plurality of synthesis scanning line signals and obtain a power intensity distribution.
