## Indications for use
PLATO ITP is intendad to optimizo multi lcaf collimator (MLC) positions or partial attenuation block shapes for intensity modulated external beam radiation therapy (IMRT) prior to final dosimetry planning on PLATO RTS extemal beam planning. Once the optimization is complete, the dose distribution and dnce-volume histogram curves are displayed for the user to evaluate. The optimized plan can be saved for final dose calculation and plan output using PLATO RTS.
