Title:
An X-ray CT scanner and a control program
Document Type and Number:
Japanese Patent JP6073675
Kind Code:
B2
Abstract:
An X-ray computed tomography (CT) apparatus includes a detector, and processing circuitry. The detector is configured to output, at each incidence of an X-ray photon, a signal enabling measurement of an energy value of the X-ray photon. Processing circuitry is configured to estimate an energy range to be used for imaging based on an imaging condition and to reconstruct X-ray CT image data using counting information to which an energy value within the energy range is associated among pieces of counting information that are collected from individual signals output by the detector at each incidence of an X-ray photon that has been irradiated from an X-ray tube and has passed through a subject, and in which a counting value and an energy value of X-ray photons incident to the detector are associated with each other.
