摘要： The techniques and device provided herein relate to regulating a source generator in an X-ray based equipment. In particular, an X-ray system is provided that comprises an X-ray generator and a reference detector system that regulates the output of the X-ray generator. The reference detector system comprises a direct channel that allows at least a portion of the photons to directly reach the detector crystal and a plurality of fluorescent channels, such that photon flux entering the reference detector from the fluorescent channels is negligibly impacted by variations of beam spots, shapes and/or positions.

摘要： Methods for generating a multiple-energy X-ray pulse. A beam of electrons is generated with an electron gun and modulated prior to injection into an accelerating structure to achieve at least a first and specified beam current amplitude over the course of respective beam current temporal profiles. A radio frequency field is applied to the accelerating structure with a specified RF field amplitude and a specified RF temporal profile. The first and second specified beam current amplitudes are injected serially, each after a specified delay, in such a manner as to achieve at least two distinct endpoint energies of electrons accelerated within the accelerating structure during a course of a single RF-pulse. The beam of electrons is accelerated by the radio frequency field within the accelerating structure to produce accelerated electrons which impinge upon a target for generating Bremsstrahlung X-rays.

摘要： An x-ray generator has a beam guidance system including an air coil and a toroidal solenoid coil, a ring anode surrounding the patient to be examined and arranged axially offset relative to the beam guidance, and individually driveable electron-optical components couple the electrons, which orbit on a circular specified path in the magnetic dipole field of the air coil, out of that path, deflect them in the axial direction, and focus them onto a segment of the ring anode allocated to the respectively activated out-coupling element.

摘要： A portable x-ray tube 68 for producing x-rays, the tube 68 having an energy source 74 which directs energetic particles or photons at an electron multiplier 80 coupled to the energy source 74. A voltage source 84 applies a multiplier voltage across the electron multiplier 80. When triggered by the energy source 74, the electron multiplier 80 creates a multitude of electrons 28 directed towards a target anode 90 that receives the electrons and produces x-rays 30. The target anode 90 is coupled at a voltage difference of at least 3 kV relative to the electron multiplier 80 so as to define an electron acceleration region 32 between the electron multiplier 80 and the target anode 90. The target anode 90 contains an element having an atomic number greater than 11. A low pressure enclosure 70 contains the electron multiplier 80 and the target anode 90. The low pressure enclosure 70 includes a window 92 for allowing the x-rays 30 to pass through substantially unchanged.

摘要： A small, low cost, low power, and portable x-ray source that produces an x-ray flux that is sufficient to produce high quality x-ray images on suitable x-ray sensitive films. The source includes a vacuumated chamber that is filled with a heavy atomic weight gas at low pressure and an x-ray emitter. The chamber is in a magnetic field and an oscillating electric field and generates an Electron Cyclotron Resonance (ECR) plasma having a ring of energetic electrons inside the chamber. The electrons bombard the x-ray emitter which in turn produces x-ray radiation in a given direction. A pair of magnetic members generate an axisymmetric magnetic mirror trap inside the chamber. The chamber may be nested within a microwave resonant cavity and between the magnets, or the chamber and microwave cavity may be a single composite structure. The source is useful to make x-ray photographs virtually anywhere and may be battery powered.
