What is it indicated for?

The ModuLeaf is a conformal radiation therapy and radiosurgery device that delivers a shaped X-ray beam from a radiation therapy source. The ModuLeaf is attached to a linear accelerator and consists of a series of pairs of tungsten leaves that collimate the radiation delivery to a target based on a treatment plan generated by planning software. The device is used to help the clinician deliver well-defined target volumes of radiation while sparing the surrounding tissues and organs.

Indications for use as stated in the FDA summary.
