Industry Background

On an ultrasound console the trackball drives pointer position for calipers, annotations, body-marker placement, and region-of-interest selection in Doppler and elastography modes. The trackball module is a self-contained assembly (ball + ring + sensor) that can usually be swapped without disassembling the console. Trackball replacement is part of standard refurbishment because gel ingress and ball wear are routine causes of cursor drift and unresponsive pointing.
