Abstract
A system and a method are provided for intensity modulated radiation treatment. A field on a patient (544) for irradiation is first defined. A beam of radiation (530) is then provided. This beam (530) passing through an opening defined by a beam-shielding device (540, 542). In the preferred embodiment, the beam shielding device is a single jaw (540) and a single collimator section (542). Single jaw (540) and single collimator section (542) are moved in one direction at different velocities to vary the opening for radiation beam (530). Single jaw (540) and single collimator section (542) move without rotation to provide intensity modulated radiation treatment
