BACKGROUND Modern nonfluoroscopic mapping systems construct 3D electroanatomic maps by tracking intracardiac catheters. They require specialized catheters and/or dedicated hardware. We developed a new method for electroanatomic mapping by merging detailed 3D models of the endocardial cavities with fluoroscopic images without the need for specialized hardware. This developmental work focused on ...

To determine the morphometric landmarks and anatomical variants relevant to arthroscopic approach deep gluteal space. Twenty spaces from cadaveric specimens were dissected. The of sciatic nerve (SN) determined according Beaton Anson classification. A study distances in subgluteal space was carried out define references achieve a safe for piriformis syndrome [GT-SN=Distance greater trochanter (G...

OBJECTIVES/HYPOTHESIS While there are many benefits to the endoscopic endonasal approach to the infratemporal fossa, involvement of the petrous portion of the internal carotid artery (ICA) poses a unique challenge. The endoscopic endonasal approach requires establishing the relationship of the petrous ICA to anatomical landmarks to guide the surgeon. This study evaluates the relationship of pet...

BACKGROUND Lateral ulnar collateral ligament (LUCL) reconstruction requires proper understanding and identification of anatomic structures about the lateral elbow. The insertion site of the LUCL is based on the supinator tubercle. PURPOSE To characterize the supinator tubercle relative to other surrounding anatomic landmarks. STUDY DESIGN Descriptive laboratory study. METHODS Computed tom...

OBJECTIVES To design, implement in Java, and evaluate a method and means for the automated localization of artificial landmarks in optical images for tuned-aperture computed tomography (TACT) that allows the replacement of radiographic with optical landmarks. METHODS Circular, colored, optical landmarks were designed to provide flexibility with regard to landmark constellation, imaging equipm...
