Ultrasound diagnosis apparatus and controlling method

According to an embodiment, an analyzer analyzes the state of a tissue at a position in a subject from which an ultrasound wave that is transmitted by an ultrasound probe into the subject is reflected, the analysis being on the basis of a received signal of the ultrasound wave. A signal acquiring unit acquires noises signal information corresponding to an area that is analyzed by the analyzer. A noise area extracting unit determines, regarding each area analyzed by the analyzer, whether the received signal that is used for the analysis performed by the analyzer is a noise signal, the determination being on the basis of the noise signal information acquired by the signal acquiring unit. A display controller configured controls a display unit such that the display unit displays an area regarding which the area extracting unit determines that the received signal is a noise signal.

Ultrasonic diagnostic apparatus and ultrasonic image processing apparatus

A scanner transmits and receives ultrasonic waves at a specified pulse repetition frequency (PRF). A storage stores received signals acquired through the transmission and reception. A calculator generates a Doppler spectrum image by executing frequency analysis on the received signals. A display displays the Doppler spectrum image. When a desired Doppler velocity range for the displayed Doppler spectrum image is inputted, a processor reads out the received signals from the storage, and executes a resampling process on the read-out received signals at a sampling frequency corresponding to the desired Doppler velocity range. The calculator generates a new Doppler spectrum image by executing frequency analysis corresponding to the desired Doppler velocity range on the received signals having been subjected to the resampling process by the processor. The display displays the new Doppler spectrum image.
