Ultrasound diagnostic apparatus

An ultrasound diagnostic apparatus comprising:

• a targeted cross-section specifying unit that specifies a targeted cross-section which is a cross-section classification of an ultrasound tomographic image that needs to be formed;
• a match rate calculation unit that executes cross-section recognition processing on a target image, which is an ultrasound tomographic image formed in response to an instruction from an examiner, to calculate a match rate between a cross-section classification of the target image and the targeted cross-section;
• and
• an output unit that outputs, based on a support information database in which support information related to an operation of the ultrasound diagnostic apparatus and used to support formation of a targeted cross-section, which is a cross-section classification of an ultrasound tomographic image that needs to be formed by the examiner, is associated with each match rate, support information with a content tailored to the match rate calculated by the match rate calculation unit.
