A new method for real-time co-registration of 3D coronary angiography and intravascular ultrasound or optical coherence tomography

Cardiovasc Revasc Med. 2014 Jun;15(4):226-32. doi: 10.1016/j.carrev.2014.03.008. Epub 2014 Mar 19.

Abstract

We present a new clinically practical method for online co-registration of 3D quantitative coronary angiography (QCA) and intravascular ultrasound (IVUS) or optical coherence tomography (OCT). The workflow is based on two modified commercially available software packages. Reconstruction steps are explained and compared to previously available methods. The feasibility for different clinical scenarios is illustrated. The co-registration appears accurate, robust and induced a minimal delay on the normal cath lab activities. This new method is based on the 3D angiographic reconstruction of the catheter path and does not require operator's identification of landmarks to establish the image synchronization.

Keywords: Co-registration; Intravascular ultrasound; Optical coherence tomography; Quantitative coronary angiography.
