An automated blood vessel extraction using high-order local autocorrelation (HLAC) on retinal images is presented. Although many blood vessel extraction methods based on contrast have been proposed, a technique based on the relation of neighbor pixels has not been published. HLAC features are shift-invariant; therefore, we applied HLAC features to retinal images. However, HLAC features are weak...

Maximum intensity projection (MIP) studies of CT angiography (CTA) images are a widely used tool for artery and vein visualization especially in the brain. Due to their high CT intensity bone structures lead to visualization artifacts in MIP studies, therefore they have to be removed to get an undistorted view of the vessel structures. Often this removal is possible by a rigid registration step...

Susceptibility differences between tissues can be utilized as a new type of contrast in MRI that is different from spin density, T1-, or T2-weighted imaging. Signals from substances with different magnetic susceptibilities compared to their neighboring tissue will become out of phase with these tissues at sufficiently long echo times (TEs). Thus, phase imaging offers a means of enhancing contra...

laryngeal mask is a supraglothic instrument for ventilation of patients who are under anesthesia. insertion of laryngeal mask requires maintaining sufficient depth of anesthesia to avoid airway reflex (gagging, coughing and spasms). the present study investigated two techniques of anesthesia with propofol-atracurium and thiopental-atracurium to facilitate insertion of the laryngeal mask, term o...
