Magnetic Resonance Imaging Compatible Remote Catheter Navigation System, Mohammad Ali Tavallaei
Magnetic Resonance Imaging Compatible Remote Catheter Navigation System, Mohammad Ali Tavallaei
Electronic Thesis and Dissertation Repository
Many vascular and cardiac diseases are diagnosed and treated using a medical technique known as percutaneous transluminal catheter intervention (PTC). In PTC, the interventionalist inserts a catheter into the vasculature, and using the vessel as the guiding passageway, the catheter is navigated to desired anatomical targets where it would be used for various purposes such as catheter ablation for the treatment/management of cardiac arrhythmias. The catheterization procedure is conventionally guided with x-ray fluoroscopic imaging and more recently, but rarely, with Magnetic Resonance Imaging (MRI). X-ray imaging irradiates the patient directly during the procedure, and the staff and interventionalists indirectly through …
Biplanar Fluoroscopic Analysis Of In Vivo Hindfoot Kinematics During Ambulation, Janelle Ann Cross
Biplanar Fluoroscopic Analysis Of In Vivo Hindfoot Kinematics During Ambulation, Janelle Ann Cross
Dissertations (1934 -)
The overall goal of this project was to develop and validate a biplanar fluoroscopic system and integrated software to assess hindfoot kinematics. Understanding the motion of the foot and ankle joints may lead to improved treatment methods in persons with foot and ankle pathologies. During gait analysis, skin markers are placed on the lower extremities, which are defined as four rigid-body segments with three joints representing the hip, knee and ankle. This method introduces gross assumptions on the foot and severely limits the analysis of in depth foot mechanics. Multi-segmental models have been developed, but are susceptible to skin motion …
Assessment Of Normal Knee Kinematics Using High-Speed Stereo-Radiography System, Vasiliki Kefala
Assessment Of Normal Knee Kinematics Using High-Speed Stereo-Radiography System, Vasiliki Kefala
Electronic Theses and Dissertations
The measurement of dynamic joint kinematics in vivo is important in order to understand the effects of joint injuries and diseases as well as for evaluating the treatment effectiveness. Quantification of knee motion is essential for assessment of joint function for diagnosis of pathology, such as tracking and progression of osteoarthritis and evaluation of outcome following conservative or surgical treatment. Total knee arthroplasty (TKA) is an invasive treatment for arthritic pain and functional disability and it is used for deformed joint replacement with implants in order to restore joint alignment. It is important to describe knee kinematics in healthy individuals …
