项目摘要
ABSTRACT
Seven Investigators from the RR&D Center for Limb Loss and MoBility (CLiMB) are requesting funds to augment
their existing biplane fluoroscopy system. This system will support a variety of projects that are working towards
the Center’s core mission of improving the quality of life and functional status of both Veterans who are at risk
for lower extremity amputation, and Veterans and service members who have undergone lower extremity
amputation.
CLiMB’s Biplane Fluoroscopy Laboratory (Bldg. 101, room GW11) is a 750 sq ft space in which resides the
Biplane Fluoroscopy System and our custom analysis software, Constellation. A pair of X-ray imaging systems
concurrently record bone motion of the foot while a research subject performs functional tasks. The major
components of each of the two X-ray arms are: A) an X-ray tube (Model G-1082, Varex Imaging, Salt Lake City,
UT), B) a 40 cm X-ray image intensifier (Model TH 9447, Thales Electron Devices, Moirans, France), C) a high-
voltage X-ray generator (Epsilon, EMD Technologies, Quebec, Canada), D) a telescoping ceiling-mounted tube
crane (HALO, CORElabs, Englewood, CO), E) an X-ray beam collimator (Model R 225, Ralco Medical
Components, El Dorado Hills, CA), and F) a high-speed video camera (Phantom v641, Vision Research, Wayne,
NJ). A custom timing module ensures that these two systems generate pulsed (up to 150 frames/second) or
continuous X-rays synchronously. The system was mostly designed and developed by Imaging Systems and
Service, Inc (Painesville, OH), with our group contributing the walkway and image intensifier stand designs.
For this ShEEP proposal, we aim to augment the biplane system by effectively temporarily replacing the IIs and
high speed video cameras with two digital radiography (DR) flat panels (Varex XRD 43X43 R/F) with custom
support stands, grids, and protective holders. The DR panels will also require some custom software
development. We will be purchasing the upgraded system hardware and software from Imaging Systems and
Service, Inc., who also provided the existing biplane system hardware. The DR panels will allow for the easy
reconfiguration of the biplane laboratory to study lower limbs for such pathologies as transtibial or transfemoral
amputations, knee osteoarthritis, or distal femur fractures.
The biplane fluoroscopy system will support a number of projects that span the Center’s research portfolio,
including: 1) trans-tibial socket fit; 2) trans-femoral socket fit; 3) trans-femoral contralateral knee arthritis; 4) knee
mechanics during backpack loading; and 5) distal femur fracture site motion.
摘要
来自RR&D肢体丧失和移动中心(CLiMB)的七名调查人员正在申请资金,
他们现有的双平面透视系统。该系统将支持正在努力实现的各种项目
该中心的核心使命是改善处于危险中的退伍军人的生活质量和功能状态
下肢截肢,以及经历下肢截肢的退伍军人和服务人员
截肢
CLiMB的双平面透视实验室(101号楼,GW 11室)是一个750平方英尺的空间,
双平面透视系统和我们的定制分析软件Constellation。一对X射线成像系统
在研究对象执行功能性任务时同时记录足部的骨骼运动。主要
两个X射线臂中的每一个的部件是:A)X射线管(型号G-1082,VarexImaging,湖城
UT),B)40 cm X射线图像增强器(型号TH 9447,Thales Electron Devices,Moirans,France),C)高-
电压X射线发生器(Epperiment,EMD Technologies,魁北克,加拿大),D)伸缩式天花板安装管
起重机(HALO,CORElabs,Englewood,CO),E)X射线束准直器(型号R 225,Ralco Medical
Components,埃尔多拉多山,CA),和F)高速摄像机(Phantom v641,Vision Research,韦恩,
NJ)。自定义定时模块确保这两个系统产生脉冲(高达150帧/秒)或
连续X射线同步。该系统主要由Imaging Systems设计和开发,
Service,Inc(Painesville,OH),我们的团队负责走道和影像增强器支架设计。
对于这个ShEEP提案,我们的目标是通过有效地临时替换IIs来增强双平面系统,
高速摄像机,带两个数字X射线摄影(DR)平板(Varex XRD 43 X43 R/F),
支架、格栅和保护支架。DR面板还需要一些定制软件
发展我们将从Imaging Systems购买升级的系统硬件和软件,
服务公司,他还提供了现有的双翼机系统硬件。DR面板将允许轻松
重新配置双平面实验室,以研究下肢的经胫骨或经股动脉等病变
截肢、膝关节骨关节炎或股骨远端骨折。
双平面透视系统将支持该中心研究组合中的许多项目,
包括:1)经胫骨窝匹配; 2)经股骨窝匹配; 3)经股骨对侧膝关节炎; 4)膝关节
背包负荷期间的力学;和5)股骨远端骨折部位运动。
