The smart arc machine is designed to provide the tools to create rotational intensity-modulated radiation therapy (IMRT) plans using a conventional linear accelerator and a conventional multileaf collimator (MLC). Plans are delivered while the gantry rotates around the patient. The intensity of the radiation is modulated and the shape of the beam is dynamically adjusted by moving the MLC leaves. The gantry speed and dose rates may also be changed during the rotation. This provides you with the potential to create plans that are comparable to your standard IMRT plans but with a shorter treatment time.
