An ultrasonic data acquisition apparatus includes an inner layer, a guiding rail surrounding the inner layer and an ultrasonic probe positioned outside of the inner layer and connected to the guiding rail. The inner layer includes an inner surface and an outer surface. The inner layer is curved along a circumference direction. The ultrasonic probe includes a far end adjacent to the tissue and a near end opposite to the far end. When the ultrasonic data acquisition apparatus is in working, the ultrasonic probe is movable relative to the inner layer along the circumference direction while keeping the far end consistently abutting against the outer surface of the inner layer. Besides, a system for acquiring ultrasonic data and a control method of the ultrasonic data acquisition apparatus are also disclosed.
