Ultrasound diagnostic apparatus for determining situation of examination

An ultrasound diagnostic apparatus comprising:

• a hardware processor configured to:
• successively acquire a plurality of ultrasound images through transmission and reception of ultrasonic waves;
• determine a diagnostic site represented by each of the plurality of ultrasound images;
• and
• determine a situation of an examination using the ultrasonic waves based on a temporal change in a degree of certainty of the determination of the diagnostic site,
• wherein the situation of the examination comprises at least one of a screening phase in which rough scan is executed to acquire the ultrasound image, a cross-section identification phase in which a scan for searching for a specific cross section to be scanned with the ultrasonic waves is performed, a diagnose phase in which measurement is performed using the ultrasound image, and a reporting phase in which the ultrasound image is stored for creating a report,
• wherein the degree of certainty is a probability that the diagnostic site represented in the ultrasound image is a determined diagnostic site, and
• wherein the hardware processor acquires one of the plurality of the ultrasound images by transmitting and receiving the ultrasonic waves in accordance with an imaging mode corresponding to the situation of the determined examination, wherein the imaging mode comprises one of a harmonic imaging method, a focus adjustment of the ultrasonic waves, a coherent factor, a frequency compound processing, and a spatial compound processing.
