Brief Summary

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Recent advancements in computational power and image processing algorithms provide opportunities for substantial reductions in radiation doses used during coronary angiography. One such advancement is spatiotemporal enhancement processing (STEP) which improves the signal to noise ratio of time sequenced angiographic data and enhances the visibility of vascular structure. This innovative STEP technique has the promise of minimizing patient and operator radiation exposure while maintaining adequate image quality. The purpose of this pilot study is to investigate a novel strategy of radiation dose reduction and data processing in coronary angiography. This pilot study will be performed in patients undergoing clinically-indicated diagnostic coronary angiography.
The study will compare angiograms acquired at ultralow radiation doses and processed with spatiotemporal enhancement software (STEP-angiograms) to standard of care angiograms (SOC-angiograms) acquired with normal radiation dose settings and no additional processing. The objectives are to assess offline whether the low radiation STEP-angiograms are of equivalent diagnostic quality as SOC-angiograms. In future research studies, the STEP software will be tested in the clinical setting to evaluate how the software may improve patient safety, enhance the overall quality of care, promote the responsible use of radiation in coronary angiography procedures, and reduce occupational radiation doses among physician and staff in the catheterization laboratory.
