Segmentation from (a) in vivo vasculature showing patient-specific basilar tip aneurysm to the (b) associated in vitro model. Note that the in vitro basilar tip model was mirrored when compared with the in vivo. (c) In vivo vasculature for patient-specific ICA aneurysm and the (d) in vitro segmented model (PCA, posterior cerebral artery; SCA, superior cerebellar artery; MCA, middle cerebral artery; ACA, anterior cerebral artery; PComA, posterior communicating artery).
