Estimating the term…
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.

A method of determining the dimensions of an object having a left edge and a right edge, said method comprising the steps of:
A system for determining the dimensions of an object having a left edge and a right edge, said system comprising:
The system of 10, further comprising further collimator means, coupled to said detection means, for significantly reducing the probability that a scattered ray formed by the intersection of one of said plurality of fan rays with said object will reach said detection means.
The system of 14, wherein each detector further comprises a light pipe coupling the scintillation means to the photomultiplier tube.
