“…Many recent applications have integrated robotic arms or tracking systems to US imaging [1][2][3][4][5][6][7]. In such systems, US calibration is a necessary task to localize 3D position and orientation of the US image, or US transmitter/receivers in the robot tooltip, tracked marker, or other coordinate frames (called "moving frame," while the fixed frame, e.g., robot base or tracking system, is called "world's frame").…”

The submillimeter accuracy requirement of US calibration makes frequent data collections unavoidable. We proposed an automated calibration setup and showed feasibility by implementing it for a robot tooltip to US image calibration. The automated method showed a similar reconstruction precision as well as repeatability compared to the manual method, while the time consumed for data collection was reduced. The automatic method also reduces the burden of data collection for the user. Thus, the automated method can be a viable solution for applications that require frequent calibrations.
