• Radiology 2007 - Coronary Calcium Scoring - This paper by Dr. McCollough et al is may be seen to be analaogous to our work in that it addresses similar issues (e.g. achieving "standard" noise levels). It could be thought of as an early draft of a Calcium Scoring profile, including both groundwork and equipment specifications.
