Method and apparatus for advanced X-ray imaging systems

摘要

The present invention pertains to an apparatus and method for X-ray imaging a human patient. A vacuum bell bonded to an X-ray radiation-permeable window that can emit X-ray radiation from a plurality of spots located 1 cm from its edge, a collimator, and a detector are used. A ring of stationary X-ray sources can also be used with a stationary collimator and a rotating slot collimator and detector. An X-ray beam can be aligned in an X-ray system by establishing a position of the beam with respect to a moving collimator at a number of points in time, monitoring the velocity of the collimator, navigating the beam to a calculated position of a hole in the collimator, and correcting the alignment of the beam based on the location of the beam on the detector.

主权项

1. An X-ray imaging system for imaging an object comprising:
a vacuum bell for creating a vacuum envelope in an X-ray source; an X-ray radiation-permeable window configured to emit X-ray radiation from a plurality of spots; a collimator located between said X-ray source and said object for projecting said X-ray radiation through said object; an X-ray detector for measuring amount of said X-ray radiation passing through said object and striking said detector; a second vacuum bell in contact with said vacuum bell for creating a second vacuum envelope in a second X-ray source; and a second X-ray radiation-permeable window configured to emit X-ray radiation from a second plurality of spots.
