Abstract
Provided are an ultrasonic signal processing device that can evaluate reliability of a velocity vector calculated by sub-pixel tracking, an ultrasonic diagnosis apparatus, and an ultrasonic signal arithmetic processing method. The ultrasonic signal processing device includes an echo signal acquisition unit that acquires an echo signal reflected by an object to be inspected, a velocity vector calculation unit that calculates a velocity vector using the echo signal, a post-parallel-movement signal generation unit that generates a post-parallel-movement signal obtained by approximately parallelly moving the echo signal, an image deformation component extraction unit that extracts an image deformation component which is a change component of a signal value due to deformation of an image from a deviation between the post-parallel-movement signal and the echo signal, and an error energy calculation unit that calculates an error energy of the velocity vector from the image deformation component.
