Quantifying cross-scatter contamination in biplane fluoroscopy motion analysis systems.
Biplane fluoroscopy is used for dynamic in vivo three-dimensional motion analysis of various joints of the body. Cross-scatter between the two fluoroscopy systems may limit tracking accuracy. This study measured the magnitude and effects of cross-scatter in biplane fluoroscopic images. Four cylindrical phantoms of 4-, 6-, 8-, and 10-in. diameter were imaged at varying kVp levels to determine th...
متن کاملPreliminary 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 کاملPaper OVERVIEW OF CONTEMPORARY INTERVENTIONAL FLUOROSCOPY PROCEDURES
Interventional fluoroscopy procedures are increasingly important in medical practice. As new procedures are introduced and validated, they tend to replace the equivalent surgical procedure. There is wide variation in patient dose, both among procedures and for a specific procedure. Stochastic risk is present, but interventional fluoroscopy procedures may also present deterministic risk. Radiati...
متن کامل3D Vessel Reconstruction from Biplane Angiograms using Snakes
In this paper, we propose a physics-based model to segment and reconstruct coronary vessels from biplane angiograms. We use the snake technique to model the vessel, the snake deforms in space to adjust its projections to the image data. In this way, segmentation and 3 0 reconstruction are unified into the same procedure assuring that only plausible vessel shapes will be detected. The method is ...
