What is it indicated for?

The NOMOS TALON Positioning and immobilization System is intended to provide an invasive means to repeatedly position and immobilize a patient during:

a) diagnostic procedures in preparation for radiation therapy (RT) treatments of the head or head and neck, and

b) during treatment procedures in the radiation therapy suite.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
