ABSTRACT:
The present invention relates to a computer tomography system which measures the thickness and edge position of hot-rolled steel. X-rays produced by two X-ray sources are directed, through the sample being measured, to a plurality of radiation detectors. The radiation detectors measure the attenuation of the X-rays caused by the sample. The attenuation levels sensed by each detector are correlated with each detector's physical location. This information is collected as each X-ray source illuminates the radiation detectors. The collected information is triangulated or averaged, as necessary, to determine the dimensions and position of the measured sample.
