Abstract :
X-ray coronary angiography (CAG) is one of widely used imaging modalities for clinical diagnosis and interventional treatment of coronary artery diseases. CAG sequences covering one or several cardiac cycles record morphological as well as dynamic information of coronary arterial vessels and related myocardium during cardiac cycles. Detection of coronary arterial dynamic information from CAG sequences is one of important issues in post-processing CAG images. In this paper, two methods based on optical flow and elastic registration respectively are proposed to quantitatively estimate coronary arterial displacement fields from dynamic CAG sequences. Their performances are validated with clinical data and application scopes are analyzed.
