Automatic aortic valve landmark localization in coronary CT angiography using colonial walk
Fig 8
Colonial walk-localized landmarks in a test volume of a normal patient during the cross-validation on 40 non-TAVI volumes.
(a) Successful walk with the minimum walk variance towards the non-coronary hinge point in global phase. The blue point refers to the initial position of the walker. (b) Local estimation of the non-coronary and right-coronary hinge points, the commissure point between them, and the right coronary ostium. (c) Corresponding ground truth.
