Abstract
There is no question that technological development and innovation in CT imaging proceeds at a rapid pace. New techniques for dual-energy image acquisition are constantly being developed and current technologies are being refined. The demands of the field of cardiac radiology are such that improvements in image quality as well as a push towards using CT for tissue characterization are being pursued with vigor. This chapter aims to discuss the various methods by which dual-energy CT data can be acquired, the advances in x-ray tube and detector technology and finally a discussion regarding advances in image acquisition and reconstruction with a view to reducing radiation exposure.
