Tongue‐pellet tracking by a computer‐controlled x‐ray microbeam system

A high‐voltage flying‐spot‐type x‐ray microbeam generator for computer‐controlled radiography has been constructed, and a preliminary experiment on automatic tracking of pellets placed on the tongue has been conducted. Main operational features of the x‐ray system are described, and some early data on the tongue movements of a Japanese subject uttering syllable sequences are shown.
