Systems and Methods for Shutterless Afterglow Measurement

The present specification discloses a system that employs a shutter-less method of measuring afterglow, in which the start and termination of the stimulating radiation from the radiation source is controlled electronically. A fast decay scintillator may be used in the beam path to monitor and track the rise and fall of the stimulating radiation to determine the dose and full cessation of the stimulating radiation. This information is used to calculate the afterglow for a slow decay scintillator. This method can also be used to calibrate and normalize scanned image data and produce an enhanced image. The fast decay scintillator is used as a monitoring or tracking device to be able to determine radiation source decay.
