The primary objective of this study is to collect CT scan data without ECG-leads attached to the human subject. This data is intended to represent a typical range of clinical scenarios in which Cardiac CT imaging is used.

Data collected in this study will be used for technology development, scientific evaluation, marketing and education, and regulatory submissions for future products. This is a pre-market, prospective, open-label, non-randomized, single arm data collection clinical study conducted at one site in the United States of America.
