Abstract
Provided are a calibration apparatus and method that may be used for setting a magnitude of an electric pulse based on a result obtained by imaging at least one imaging object, and that may be used for calibrating by mapping at least one photon energy corresponding to an absorption edge of at least one calibration object.
Claims24
A calibration apparatus, comprising:
- an image generator which generates an image of at least one imaging object;
- a setter which sets a threshold which relates to a magnitude of an electric pulse based on a result obtained by generating the image of the at least one imaging object;
- and
- a calibrator which calibrates by mapping at least one photon energy which corresponds to an absorption edge of at least one calibration object.
