Abstract:
1. A system configured to expose a target to x-ray radiation, the system comprising: at least one source of radiant energy, where at least a first portion of the radiant energy lies within an x-ray spectrum, and where the source is configured so that the first portion of the radiant energy traverses at least a portion of a scanning volume; a filter situated between the source and the portion of the scanning volume; a conveying apparatus configured to impart relative motion between an exposure-limited subject and the portion of the scanning volume; a conveyance monitor configured to generate conveyance data reflecting at least a conveyance state of the exposure-limited subject; a first radiant energy sensing apparatus configured to sense radiant energy from the source and to generate source radiant energy data; a dose controller configured to acquire conveyance data, source radiant energy data, and a signal related to subject dose data, and to generate a measure that at least a portion of the exposure-limited subject has acquired a dose of radiant energy above a dose threshold; and wherein the dose of radiant energy is representative of an amount of radiant energy absorbed by the exposure-limited subject.
