Abstract: The present invention pertains to an apparatus for generating a charged particle beam comprising a magnetic element for controlling the profile of the beam in a predetermined plane. A cathode can be provided for emitting charged particles and an anode for accelerating the charged particles along an axis of travel. The present invention also pertains to a method for generating a particle beam that has a uniform profile in a predetermined plane comprising inducing emission of charged particles from an emitter, accelerating those particles along and toward an axis of beam travel, generating a magnetic field with a component aligned with the axis of beam travel but different in the predetermined plane than at the emitter, and modifying the beam profile.

Abstract: The present invention pertains to an apparatus and method for X-ray imaging wherein a radiation source comprising rows of discrete emissive locations can be positioned such that these rows are angularly offset relative to rows of sensing elements on a radiation sensor. A processor can process and allocate responses of the sensing elements in appropriate memory locations given the angular offset between source and sensor. This manner of allocation can include allocating the responses into data rows associated with unique positions along a direction of columns of discrete emissive locations on the source. Mapping coefficients can be determined that map allocated responses into an image plane.
