Preliminary model-based validation of a biplane fluoroscopy system
Background Biplane fluoroscopy can directly track the motion of bones and therefore measure joint kinematics. Our prior markerbased work has demonstrated the ability of our system to accurately and precisely track the motion of known objects (i.e., tantalum beads) [1]. In this study, we present the preliminary bone-based validation of our system by tracking the bones of the foot from cadaveric ...
متن کاملPreliminary marker-based validation of a novel biplane fluoroscopy system
Materials and methods Biplane Fluoroscopy System: The system consists of two Philips BV Pulsera C-arms set in custom frames around a raised floor with a radiolucent imaging area. X-ray images are captured with high speed (1000fps) cameras. Validation Object: 1.6mm tantalum beads were placed in a machined block (wand) then measured to 7 microns with a Coordinate Measuring Machine to determine th...
متن کاملMarker-based validation of a biplane fluoroscopy system for quantifying foot kinematics.
INTRODUCTION Radiostereometric analysis has demonstrated its capacity to track precise motion of the bones within a subject during motion. Existing devices for imaging the body in two planes are often custom built systems; we present here the design and marker-based validation of a system that has been optimized to image the foot during gait. METHODS Mechanical modifications were made to pair...

آزمون انطباقی رایانه ای (cat) روشی نوین برای سنجش سطح علمی دانش آموزان می باشد. در حقیقت آزمون های رایانه ای با سرعت بالایی به سمت و سوی جایگزین عملی برای آزمون های کاغذی می روند (کینگزبری، هاوسر، 1993). مقاله حاضر به دنبال آزمون انطباقی رایانه ای برای ترجمه می باشد. بدین منظور دو پرسشنامه مشتمل بر 55 تست ترجمه میان 102 آزمودنی و 10 مدرس زبان انگلیسی پخش گردید. پرسشنامه اول میان 102 دانشجوی س...
Evaluation of automated statistical shape model based knee kinematics from biplane fluoroscopy.
State-of-the-art fluoroscopic knee kinematic analysis methods require the patient-specific bone shapes segmented from CT or MRI. Substituting the patient-specific bone shapes with personalizable models, such as statistical shape models (SSM), could eliminate the CT/MRI acquisitions, and thereby decrease costs and radiation dose (when eliminating CT). SSM based kinematics, however, have not yet ...
