Abstract

This letter proposes the use of ultrasound computed tomography (USCT) for handwriting by imaging sound velocity changes in a medium caused by a rod. The rod was used as a writing object, and the tomographic instrument was able to process the data over time with a temporal frequency of 4 frames per second. Tests are carried out in writing various words and letters using USCT data and automatic imaging software. The work shows the functional imaging capability offered by the USCT system combining qualitative and temporal imaging features.
