ULTRASONIC DIAGNOSIS APPARATUS AND AUTOMATIC DIAGNOSIS SUPPORT APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic diagnosis apparatus and an automatic diagnosis support apparatus for improving efficiency of diagnosis.SOLUTION: A state space database 18 stores data of a state space based on a plurality of measurement values of a plurality of measurement items associated with ultrasonic scanning with regard to a plurality of healthy subjects. An ultrasonic probe 22 transmits/receives ultrasonic waves. A transmission/reception part 24 scans a subject to be diagnosed with ultrasonic waves via the ultrasonic probe 22. A measurement value calculation part 28 calculates a plurality of values of a plurality of ultrasonic measurement items with regard to the subject to be diagnosed based on outputs from the transmission/reception part 24. A second Mahalanobis distance calculation part 30 calculates Mahalanobis distances of a plurality of calculated measurement values in the state space. A disease presence/absence determination part 32 compares the calculated Mahalanobis distances with a threshold value to determine presence/absence of a disease of the subject to be diagnosed.
