BACKGROUND Sylvian fissure (SF) is an important corridor in neurosurgery, and the end of sylvian fissure (eSF) represents the optimal target area to expose suitable recipient artery in STA-MCA bypass. Unfortunately little have been addressed concerning its relationship with external cranial surface. OBJECTIVE Correlation between Squamous Suture (SS) and SF was investigated. METHODS 50-adult...

This statistical primer presents the landmark analysis method, exploring its appropriate use and interpretation while recognizing its limitations. This observational method is used for comparing time-to-event outcome between groups determined during study follow-up. The goal of the landmark method is to estimate in an unbiased way the time-to-event probabilities in each group conditional on the...

This paper proposes a novel method for image registration of lung CT scans. Our approach consists of a procedure for automatically establishing landmark correspondences in lung CT scan pairs and an elaborate variational image registration scheme. The landmark information is incorporated into the registration scheme as pre-registration using the landmark-based Thin-Plate-Spline (TPS) method. The...
