the ultrasound probe is provided with a plurality of pressure detecting units each of which is configured to detect a pressure applied to the patient from the ultrasound probe, and
based on a difference between the detected pressures detected by the plurality of pressure detecting units, the detecting unit detects a direction from a position in which the pressure detecting unit having detected a larger detected pressure is provided, to a position in which the pressure detecting unit having detected a smaller detected pressure is provided.
6 . The ultrasound diagnosis apparatus according to claim 4 , wherein
the ultrasound probe includes a movement detecting unit configured to detect a positional displacement of the ultrasound probe, and
the detecting unit detects a movement direction of the ultrasound probe, based on the positional displacement of the ultrasound probe detected by the movement detecting unit.
7 . The ultrasound diagnosis apparatus according to claim 4 , further comprising: a measuring unit configured to measure a distance from a vibrator surface of the ultrasound probe to the surface of the body of the patient at each of a plurality of locations, wherein
based on the measured distances measured by the measuring unit at the plurality of locations, the detecting unit detects a direction from a location having a shorter measured distance, to a location having a longer measured distance.
8 . The ultrasound diagnosis apparatus according to claim 7 , wherein
the measuring unit performs the process of measuring the distance between the surface of the body and the vibrator surface at each of the plurality of locations once every predetermined period of time, and
the detecting unit detects a direction from a location having a smaller temporal change in the measured distance measured by the measuring unit, to a location having a larger temporal change in the measured distance.
