Describes the nature of a clinical study. Types include:
The purposes for this study are to determine the ability of volumetric dynamic 4D CTA compared to replace current single-phase CTA and eliminate venous contamination that can decrease scan accuracy. Additionally, we seek to estimate the ability of this new imaging technique (volumetric dynamic 4D CTA) to reduce the dose of intravenous iodine and radiation dose.

Our purpose for this study is to help design a therapy plan that can decrease extra radiation exposure to your heart during radiotherapy. The therapy plan will use images obtained using a dual-source CT scanner
This study aims to perform a prospective analysis of patients undergoing fibrillation ablations and compare the validity of the electroanatomical registration with superimposed angiography. In addition, this study aims to compare and understand the relationship between the cardiac vessels.
The objective of this study is to evaluate the image quality and radiation dose of a CT angiography protocol (CTA) using tube potential selection and weight-based method.

3D angiography (3DA) imaging is a valuable method for assessing cardiovascular anatomy prior to and following trans-catheter intervention. Current 3DA contributes substantially to the overall patient radiation dose for these procedures. The purpose of this work is to assess the clinical efficacy of reduced radiation dose 3DA.
