One important problem in human brain mapping research is to locate the important anatomical features. Anatomical features on the cortical surface are usually represented by landmark curves, called sulci/gyri curves. These landmark curves are important information for neuroscientists to study brain disease and to match different cortical surfaces. Manual labelling of these landmark curves is tim...

Purpose: To develop a fast landmark-based deformable registration method to capture the soft tissue transformation between the planning 3D CT images and treatment 3D cone-beam CT (CBCT) images for the adaptive external beam radiotherapy (EBRT). Method and Materials: The developed method was based on a global-to-local landmark-based deformable registration algorithm. The landmarks were first acq...

Axillary nerve injury is a risk of the deltopectoral approach to the proximal humerus. The anterior motor branch is potentially vulnerable during subdeltoid dissection. Insertion of the pectoralis major tendon is an easily identifiable landmark on the humerus. This anatomical study explored whether the superior aspect of the pectoralis major tendon is a useful landmark for localizing the anteri...

Facial landmark detection is an essential initial step for a number of facial analysis research areas such as expression analysis, 3D face modeling, facial attribute analysis, and person recognition. It is a well researched problem that has seen a surge of interest in the past couple of years. However, most state-of-the-art methods still struggle in the presence of extreme head pose, especially...

OBJECTIVE The aim of this study is to find out if an ultrasound technique has advantages over the conventional landmark technique. METHODS This is a prospective randomized comparative study on 120 patients requiring central venous cannulation of the right internal jugular vein. The study comprised of two groups: ultrasound and landmark groups, each consisting of 60 patients. The outcome measu...

29 30 It is not known how egocentric visual information (location of a target relative to the self) and 31 allocentric visual information (location of a target relative to external landmarks) are integrated 32 to form reach plans. Based on behavioural data from rodents and humans we hypothesized that 33 the degree of stability in visual landmarks would influence the relative weighting. Furtherm...
