摘要： A beam modifier shapes the distribution of a dose delivered to a target by a radiation beam emitted from a beam emitter of a radiotherapy device, particularly a beam that delivers a high radiation dose within a single, short period of time (e.g., less than a second). Elements of the beam modifier (e.g., rods) include material that can block or attenuate the beam. The elements can be dynamically and quickly configured to form an opening or transparent area through which a portion of the beam can pass unimpeded and to present different thicknesses of material to block or attenuate other portions of the beam, in this manner shaping the dose distribution at the target while protecting surrounding tissue.

摘要： A radiation suite includes a room having a floor, a ceiling, and one or more walls, a radiation system including a gantry enclosing a radiation source and a couch, and an image projection system operable to project an image on a projection surface on at least a portion of the gantry and/or the couch, providing a calming environment for a patient to relax. The image projection system comprises a computer and one or more projectors operably controlled by the computer. The computer comprises a mapping software operable to map an image file to the projection surface. The one or more projectors are operable to project the mapped image file on the projection surface.
