摘要:
The presently disclosed subject matter is intended to correctly determine an ambient sound velocity at each level of pixels or line images constituting an ultrasound image, and construct a high-precision ultrasound image. A region-of-interest setting unit sets a region of interest on an ultrasound image. A transmission focus control unit gives a transmission focus instruction, so that a transmitting circuit performs transmission focusing on the region of interest. A set sound velocity specification unit specifies a set sound velocity used to perform reception focusing on RF data. A focus index calculation unit performs reception focusing on the RF data for each of a plurality of set sound velocities to calculate the focus index of the RF data. An ambient sound velocity determination unit determines the ambient sound velocity of the region of interest on the basis of the focus index for each of the plurality of set sound velocities.
