Historical development of cardiovascular CT

The use of X-ray computed tomography (CT) to image the heart has increased exponentially over the last decade. This ↑ is largely the result of technological improvements that have rendered cardiac images less susceptible to artefacts arising from cardiac motion and at significantly reduced radiation doses. However, these artefacts have not been abolished entirely. The ability to reliably acquire low-dose, high-quality cardiovascular CT (CCT) datasets is predicated in part on an understanding of the hardware and software used to generate them, which in turn may be better understood by reviewing briefly the development of the CT scanner from initial models to the current state-of-the-art equipment. This chapter describes the historical developments in the field.
