What is it indicated for?
The Monaco system is used to create treatment plans for any cancer patient for whom external beam intensity modulated radiation therapy (IMRT) has been prescribed. The system will calculate and display, both on-screen and in hard-copy, either two- or three-dimensional radiation dose distributions within a patient for a given treatment plan set-up.
The Monaco product line is intended for use in radiation treatment planning using generally accepted methods for contouring, image manipulation, simulation, image fusion, plan optimization and QA and plan review.
Indications for use as stated in the FDA summary.
