Abstract: 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.

Abstract: A multileaf collimator includes a plurality of beam-blocking leaves of a first type and a plurality of beam-blocking leaves of a second type. The beam-blocking leaves of the first type are alternatingly arranged with the beam-blocking leaves of the second type side by side. Each of the beam-blocking leaves of the first type has a trapezoidal geometry viewed in the leaf longitudinal moving direction comprising a wider end and a narrower end with the wider end being proximal to a source. Each of the beam-blocking leaves of the second type has a trapezoidal geometry viewed in the leaf longitudinal moving direction comprising a wider end and a narrower end with the wider end being distal to the source.

Abstract: In a beam filter assembly, a base filter is employed to modify a beam quality of a radiation beam of a base energy level and a first filter slice is stacked with the base filter to modify a beam quality of a radiation beam of a first energy level higher than the base energy level. In a beam filter positioning device, a base stage carries a base filter and a first stage carries a filter slice. The base stage is provided with a first engagement site and a second engagement site. The first stage is provided with a first engagement site, a second engagement site, and an open port. The first stage and the base stage are each independently movable relative to the beamline. The first stage is engageable with the base stage when at least one of the first and second engagement sites of the first stage is aligned with at least one of the first and second engagement sites of the base stage, and is further movable with the base stage in unison when engaged.
