for viewing and interpretation, after which they are sent to an image communication system for storage, archiving, and communication to various remote locations, if needed.

Schematic illustration of the basic concept for DBT and DRT is related to the principle underlying conventional tomography, in which the x-ray tube moves through various angles (limited arc) while the detector is stationary, capturing several images during the sweep. Schematic illustration of a CT of a patient who is scanned as the x-ray tube coupled to special electronic detectors rotate around the patient to collect and measure attenuation readings as illustrated.

      Image communication systems include picture archiving and communication systems (PACS) and information systems, including hospital information systems (HIS) and radiology information systems (RIS); Cloud PACS, a technology derived from cloud computing; Vendor Neutral Archives (VNAs); and Enterprise Imaging.

Schematic illustration of the major system components of a PACS make use of digital technologies for storage, display, and communication of digital images acquired by all digital modalities.

      Picture archiving and communication system

      Image communication systems continue to evolve into systems intended to improve the performance of PACS. These technologies include Cloud PACS, a technology derived from cloud computing; VNAs; and Enterprise Imaging. These systems are described in detail by Seeram [5].
