Detector array comprising energy integrating and photon counting cells

摘要

Among other things, one or more techniques and/or systems are described for measuring the attenuation of a line integral through an object via a photon counting cell (302) and via an energy integrating cell (304). That is, an imaging apparatus is provided that comprises a radiation source (208) and a detector array (210). The detector array is comprised of both photon counting cells (302) and energy integrating cells (304) arranged such that, during an examination of the object, attenuation of a line integral through the object is measured by at least one photon counting cell and at least one energy integrating cell. In this way, at least two substantially complete views of an object may be acquired, one from measurements yielded from the photon counting cell (and other photon counting cells) and one from measurements yielded from the energy integrating cell (and other energy integrating cells).
