  • Systems and methods of determining focal spot x-axis position from projection data
    Patent number: 5706326
    Abstract: The present invention, in one form, is a method of determining focal spot position in a computed tomography system using conventional scan data. The computed tomography system includes, in one embodiment, a bowtie filter attenuating an x-ray beam along two symmetrically disposed raypaths. The symmetrical raypaths impinge upon respective detector channels at identifiable path lengths. The raypath lengths are compared to determine whether the focal spot has shifted.
