摘要： The present invention provides a method to detect tube spits and to reduce spit related artifacts in a computed tomography imaging system. A way of detecting tube spit is to monitor the generator kilovolt or milliamp waveforms. Changes in kV waveform follow closely with those in offset-corrected projection data. If a tube-spit event is not detected, processing proceeds without tube spit correction. If a tube-spit event is detected, a tube spit correction is performed. The objective of tube-spit correction is to remove image artifacts due to the occurrence of a tube-spit event.

摘要： A method for measuring an alignment of a detector is described. The method includes determining, by a processor, the alignment of the detector with respect to a collimated radiation beam. The determination of the alignment is based on a plurality of signals from a first cell of the detector and a second cell of the detector, and is independent of a shape of the collimated radiation beam.

摘要： An electron emitter assembly and a method for adjusting a size of electron beams are provided. The electron emitter assembly includes a laser configured to emit a first light beam. The electron emitter assembly further includes a lens assembly configured to receive the first light beam. The lens assembly is configured to adjust a size of the first light beam between a first predetermined size and a second predetermined size larger than the first predetermined size. The lens assembly emits the first light beam toward a photo-cathode. The photo-cathode is configured to emit a first electron beam having a third predetermined size when the first light beam having the first predetermined size contacts the photo-cathode. The photo-cathode is further configured to emit a second electron beam having a fourth predetermined size when the first light beam having the second predetermined size contacts the photo-cathode. The electron emitter assembly further includes an anode configured to receive the first and second electrons beams from the photo-cathode.

摘要： A method for adjusting a focal spot position during a scan of a computed tomography (CT) imaging system having a z-axis. The CT imaging system includes a detector array having a plurality of detector elements and an x-ray tube configured to direct an x-ray beam towards the detector through an object to be imaged. The method includes turning on the x-ray tube and reading a z-ratio from the detector. A shift in a position of a focal spot of the x-ray tube is then determined utilizing the read z-ratio. The method further includes using a transfer function to determine a compensating electronic deflection value; and applying the electronic deflection value to the x-ray tube as at least one of a deflection voltage or a deflection current to track the focal spot in the z-axis direction.

摘要： A system for generating a tunable X-ray pulse comprises a first electron beam source configured to direct a first electron pulse of predetermined energy and pulse length towards a first interaction zone, a laser beam source configured to direct a first photon pulse of predetermined energy and pulse length towards the first interaction zone to interact with the first electron pulse. The first interaction produces a substantially monochromatic second photon pulse of higher photon energy directed towards a second interaction zone, and a second electron beam source configured to direct a second electron pulse of predetermined energy and pulse length towards the second interaction zone so that the second interaction produces an X-ray pulse of predetermined energy and pulse length in a cascaded inverse Compton scattering (ICS) configuration.
