Maximum a posteriori estimation method for aorta localization and coronary seed identification

作者：

Highlights：

• A robust method is proposed for the automatic identification of seed points (coronary ostia) for the segmentation of coronary arteries from CT image.

• Our method provides both aorta and ostia localization.

• Anatomical and geometrical priors are statistically obtained and used in MAP estimation.

• Two components are jointly found in MAP estimation (e.g. ascending and descending aortas, left and right coronary ostia).
