The intended use of the LANTIS TREATSTATION is to allow the radiation therapist to deliver treatment to the patient using the MEVATRON and all available accessories. This entails selecting a patient, selecting today's treatment for that patient, setting up and delivering the treatment fields, and recording the delivered treatment. TREATSTATION supports auto sequencing, a process of automatically downloading a group of fields or segments from the verification and record system to the control of the linear accelerator sequentially, without user intervention. In addition, LANTIS TREATSTATION supports intensity modulation (IM), a process of shaping, modifying, and moving the beam around a target to maximize the dose at the target and minimize the dose to all normal structures.

The intended use is the same as the predicate device.

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