Claim:
1. An automatic vessel access device based on real time volumetric ultrasound, the automatic vessel access device-comprising: a probe configured to generate a VOI image of a candidate vessel in a real time volume ultrasound scan mode; a control device in communication with the probe; and at least one motor in communication with the control device, the control device comprising at least one processing module configured to determine at least one control parameter based on the VOI image, and a driver module in communication with the at least one processing module and configured to operate the at least one motor according to the at least one control parameter, wherein the VOI image includes a side view and a top view of a volume of interest of the candidate vessel, and the side view and the top view are acquired by using minimum intensity projection; and the processing module determines a needle insertion angle and a needle inserting distance as the control parameters based on the position of the candidate vessel in the side view, and determines a probe rotation angle and a probe shift offset as the control parameters based on the position of the candidate vessel in the top view.
