According to one embodiment, an ultrasonic diagnosis apparatus includes a storage unit, a ultrasonic probe, a transmission/reception unit, a measured value calculation unit, a distance calculation unit, and a determination unit. The storage unit stores data of a state space based on a first measured values of a measurement item associated with an able-bodied person. The transmission/reception unit transmits ultrasonic waves to a subject via an ultrasonic probe, and generates reception signals corresponding to an ultrasonic waves reflected by the subject. The measured value calculation unit calculates a second measured value of the measurement item associated with the subject based on the reception signals. The distance calculation unit calculates a Mahalanobis distance of the subject based on the state space and the second measured value. The determination unit compares the Mahalanobis distance with a threshold to determine whether the subject has the disease evaluated by the measurement item.

Ultrasonic doppler imaging apparatus and method with blood velocity waveform processing

An ultrasonic imaging apparatus comprised of an ultrasonic transducer array that transmits ultrasonic waves to a subject under examination and receives ultrasonic waves reflected from within the subject under examination and a scan controller that controls the transducer array to transmit/receive the ultrasonic waves in the same direction repeatedly and to change the transmitting/receiving direction of the ultrasonic waves in a sectional plane of the subject under examination. The apparatus also includes a detector that detects Doppler shifted frequency data at a plurality of points in the sectional plane from a received signal by the transducer array and a display that displays blood flow of the subject. A memory stores a plurality of types of patterns having a maximum velocity, a minimum velocity and a number of frames per unit time of blood flow to be detected in various combinations. A selector selects a pattern from the types of patterns, and a controller sets a parameter for the number of times the ultrasonic waves are repeatedly transmitted/received, a parameter for a repetition period during which the ultrasonic waves are repeatedly transmitted/received, and a parameter for the number of times the direction of transmission/reception of the ultrasonic waves is changed in the scanning plane. The controller also controls the scan controller and the detector in accordance with the set parameters so as to implement the pattern selected by the selector.
