Ultrasonic diagnosis apparatus

An ultrasonic diagnosis apparatus, comprising:

• a transmission condition controller configured to set a transmission condition to be given to an ultrasonic beam radiated to scan a region of a subject to be diagnosed,
• the transmission condition including at least one transmission condition other than a transmission frequency of the ultrasonic beam and being controlled in amount according to a scanning direction of the ultrasonic beam during a scanning operation thereof for one frame of an ultrasonic image of the subject so that non-uniformity of a transmission sound field in the region is corrected;
• an ultrasonic transmitter configured to transmit the ultrasonic beam to the subject under the at least one transmission condition set by the transmission condition controller;
• and
• an image generator configured to sample a harmonics component from an ultrasonic echo signal reflected from the subject in response to transmitting the ultrasonic beam to the subject, thereby obtaining, as the ultrasonic image, a harmonic ultrasonic image of the subject from the harmonics component.

An ultrasonic diagnosis apparatus, comprising:

• a transmission condition controller configured to set, according to an operator's command, a transmission condition to be given to an ultrasonic beam radiated to scan a region of a subject to be diagnosed,
• the transmission condition including at least one transmission condition other than a transmission frequency of the ultrasonic beam and being controlled in amount according to a scanning direction of the ultrasonic beam during a scanning operation thereof for one frame of an ultrasonic image of the subject so that a transmission sound field in the region is entered into a desired state concerning the transmission sound field;
• an ultrasonic transmitter configured to transmit the ultrasonic beam to the subject under the at least one transmission condition set by the transmission condition controller;
• and
• an image generator configured to obtain the ultrasonic image of the subject from an ultrasonic echo signal reflected from the subject in response to transmitting the ultrasonic beam to the subject.

• a receiving condition corrector configured to correct a receiving condition for an ultrasonic echo signal reflected from the subject according to the at least one transmission condition set by the transmission condition controller;
• an ultrasonic transmitter configured to transmit the ultrasonic beam to the subject under the at least one transmission condition set by the transmission condition controller;
• and
• an image generator configured to process the ultrasonic echo signal into the ultrasonic image of the subject under the receiving condition corrected by the receiving condition corrector.
