Abstract:
1. A method for adjusting a flux rate of radiation x-rays emitted by an x-ray source of a scanning apparatus, comprising: detecting first x-rays, emitted by the x-ray source at a first flux rate and incident on a first x-ray detector, that have traversed a first portion of an object under examination to generate a first measurement; detecting second x-rays, emitted by the x-ray source at the first flux rate and incident on a second x-ray detector, that have traversed a second portion of the object to generate a second measurement, the second x-rays detected concurrently with the first x-rays; adjusting the flux rate of x-rays emitted by the x-ray source from the first flux rate to a second flux rate as a function of the first measurement and in coordination with a downstream motion of the object relative to the second x-ray detector; and detecting third x-rays, emitted by the x-ray source at the second flux rate and incident on the second x-ray detector, that have traversed the first portion of the object to generate a third measurement.
