Claim Text:
1. A radiation therapy device comprising: a radiation source that directs an unmodulated raw beam along a beam path toward a selected treatment zone; wherein the radiation source is a linear accelerator without a flattening filter to provide a high radiation dose; wherein the radiation dose is high energy X-rays ranging from 6 MV to 25 MV; a beam shaping device controllable to selectively collimate the unmodulated raw beam including at least one multi-leaf collimators (MLC); and a treatment planning system for delivering an Intensity Modulated Radiation Therapy (IMRT) by utilizing the raw unmodulated beam having a predetermined profile of the high energy radiation dose and using the MLC to shape and modulate the raw beam profile for a particular dose distribution, wherein by not using a flattening filter, the MLC is configured to apply a predetermined modulation of the high energy radiation dose to be applied to the predetermined treatment zone.
