According to one embodiment, a first calculation unit calculates a first feature amount concerning an edge direction in a specific region. A second calculation unit calculates a second feature amount concerning an edge intensity or a brightness value in the specific region. A storage unit stores filter characteristics. The each filter characteristic is associated with a first feature amounts range and a second feature amounts range which ultrasonic images suitable for the each filter characteristic may have. A selection unit selects a filter characteristic corresponding to both the calculated first feature amount and the calculated second feature amount. An image filter unit applies an image filter having the selected filter characteristic.

According to one embodiment, an ultrasonic diagnosis apparatus includes an ultrasonic probe, transmission unit, reception unit, control unit, adjustment unit, automatic setting unit, switching unit, manual setting unit, correction unit, and generating unit. The adjustment unit adjusts transmission/reception conditions for repeated ultrasonic transmission/reception in accordance with an instruction from the user. The automatic setting unit sets the first gain for correcting an echo signal in accordance with the adjusted transmission/reception conditions. The switching unit switches between activating and stopping the operation of the automatic setting unit. The manual setting unit sets the second gain for correcting an echo signal in accordance with an instruction from the user. The correction unit corrects an echo signal with the first or second gain. When the adjustment unit adjusts a transmission/reception condition while the automatic setting unit stops operation, the correction unit corrects an echo signal with the second gain.

In one embodiment, an ultrasonic diagnostic apparatus includes an image creating unit, an image-creation control unit and a display control unit. The image creating unit creates an ultrasound image from data created by adding a reflected wave signal of an ultrasound wave transmitted to an imaging target portion of a subject by using a reception delay time calculated from a set sound velocity set as a sound velocity in the imaging target portion. The image-creation control unit switches a set sound velocity set at a present moment in a variable range, and controls the image creating unit so as to create a plurality of ultrasound images each using a reception delay time corresponding to each of the set sound velocities to be switched. The display control unit controls display such that the ultrasound images created are displayed on a certain display unit.

A measurement data processing device measures a size of a diagnostic region from a tomographic image as two-dimensional information. An ROI width determining device determines a size of a region of interest based on the size (lateral width and longitudinal width) of the diagnostic region. An oscillation angle determining device determines a range of an angle for oscillating ultrasonic transducers based on the size. An oscillation rate determining device determines a rate for oscillating the ultrasonic transducers based on information indicating the oscillation angle and image quality. In order to acquire a three-dimensional image of the diagnostic region, the probe oscillation control device controls the oscillation of the ultrasonic transducers based on the information. A three-dimensional image processing device extracts a three-dimensional image of in the determined region of interest from the acquired three-dimensional image. A display device displays the extracted three-dimensional image. Then, the three-dimensional image based on the shape of the diagnostic region is acquired.
