Methods, system, and devices that are adapted to restrict the movement of an ultrasound transducer about at least one axis or point, and tag a plurality of frames of electronic signals indicative of information received by the ultrasound transducer with information sensed by an orientation sensor. The methods, system, and devices can generate a 3D ultrasound volume image of the patient by positioning the plurality of tagged frames of electronic signals at their respective orientations relative to the axis or point.
