How does Intensity Modulated Radiation Therapy (IMRT) differ from robotic radiosurgery and the CyberKnife® System?
A7: IMRT, Intensity Modulated Radiation Therapy, is a form of radiation therapy incorporating multi-leaf collimators on standard gantry-based linac delivery systems to better “shape” the radiation beams to the lesion volume. IMRT also utilizes inverse treatment planning software to optimize dose distribution. This is generally accepted as an improvement over conventional radiation therapy (XRT) systems, however it is still limited by many of the same constraints as conventional radiation therapy.
