Patent ID: 8721548

Claim:
An ultrasonic diagnosis apparatus, comprising: a storage unit configured to store data of a state space based on a first measured value of a measurement item associated with an able-bodied person; an ultrasonic probe; a transmission/reception unit configured to transmit an ultrasonic wave to a subject via the ultrasonic probe, receive an ultrasonic wave reflected by the subject, and generate a reception signal corresponding to the received ultrasonic wave; a measured value calculation unit configured to calculate a second measured value of the measurement item associated with the subject based on the reception signal; a distance calculation unit configured to calculate a Mahalanobis distance of the subject based on the state space and the second measured value; a determination unit configured to compare the Mahalanobis distance with a threshold to determine whether the subject has a disease evaluated by the measurement item; and a disease type discrimination unit configured to discriminate a type of the disease by calculating a similarity between a distribution of second measured values of the subject measured by the measured value calculation unit and a measured value distribution model for each of a plurality of types of diseases.
