Most ultrasound consoles use a trackball rather than a mouse because the operator's hand is already positioned at the control panel during scanning. The trackball module (ball, ring, sensor PCB) is a wear item and a frequent refurbishment part; OEMs and service vendors typically ship complete modules rather than individual balls, which simplifies replacement and avoids encoder-mismatch issues.
