A system may include emission of megavoltage radiation from a megavoltage radiation source, acquisition of a first image using an imaging device while first megavoltage radiation is emitted from the megavoltage radiation source and while a plurality of elements is between the megavoltage radiation source and the imaging device, and determination of an amount of scatter radiation based at least on areas of the acquired image corresponding to the plurality of elements. In some aspects, at least one of the plurality of elements is substantially pointed toward a focal spot of the megavoltage radiation source.

An apparatus may include a scintillator to emit light, imaging elements to capture image information based on received light, and an optical filter disposed between the scintillator and the imaging elements, wherein an opacity of the optical filter is controllable.

Variable gain imaging

An apparatus for emitting x-rays comprises a housing which contains an anode having an electron receiving surface and a cathode having an electron emitting surface. A cable couples the anode to a source of high voltage. An optical fiber secured to the cable has a proximal end coupled to a source of optical energy and a distal end configured to direct the optical energy onto the cathode's electron emitting surface. The cathode emits electrons which strike the anode to create x-ray radiation.
