Abstract:
1. An ultrasound diagnosis system including a motor driving a multi-plane ultrasound probe for acquiring image data at a voluntary scanning plane by rotating a plurality of transducers arranged in a head portion in a prescribed target angle range, the ultrasound diagnosis system comprising: a rotation drive instructing unit configured to cause rotation drive of the head portion; a rotation angle detecting unit configured to detect a rotation angle of the head portion; a rotation mechanism driving unit configured to drive rotation of the head portion; and a rotation mechanism controlling unit configured to control the rotation mechanism driving unit based on both a rotation drive instruction signal supplied from the rotation drive instructing unit and a rotation angle detection signal supplied from the rotation angle detecting unit, wherein the rotation mechanism controlling unit is configured to control a rotation drive of the plurality of transducers in a normal rotation drive mode for acquiring image data in the prescribed target angle range in a first direction, and to control the rotation drive of the plurality of transducers in a reverse rotation drive mode in a second direction opposite to the first direction up to a prescribed reversing angle automatically in response to the rotation of the head portion exceeding the target angle range; and the rotation mechanism controlling unit is further configured to control a rotation drive of the head portion under the normal rotation drive mode in the first direction when the rotation drive instruction signal is further supplied.
