The X-ray microbeam is a computer-controlled system available in the United States and Japan that uses a narrow beam of X-rays to localize and track the two-dimensional movements of small gold pellets attached to select speech structures, including the lips, jaw, tongue, soft palate, and eustachian tube.

What is x-ray microbeam?

A microbeam is a narrow beam of radiation, of micrometer or sub-micrometer dimensions. Together with integrated imaging techniques, microbeams allow precisely defined quantities of damage to be introduced at precisely defined locations.

What is microbeam radiation therapy?

Purpose: Synchrotron microbeam radiation therapy (MRT) is a method that spatially distributes the x-ray beam into several microbeams of very high dose (peak dose), regularly separated by low-dose intervals (valley dose).
