CARESTREAM OnSight 3D Extremity System What is the CARESTREAM System? A CT scan for arms and legs Allows for weight bearing examination Installed at preferred location History 1967 - Sir Godfrey Hounsfield invented the first commercially viable CT scanner. 1971 - First Brain Scan done 1980 - Notable improvements 2008 - New generation of scanners CT Scans Today High radiation dose, up to 10 mSv Lengthy process Non-weight bearing Machinery typically in specialized centers Benefits of a CT Scan Excellent cross sectional images not found on plain X-Rays Easier to distinguish tissues in different physical densities More detail in bony structures Generally $600-200 less than MRI’s per scan 5 minute scan time Downsides of CT Less soft tissue detail Risk of irradiation Exposure to radiation Conventional CT vs CARESTEAM CT Smaller ecological footprint saving time and cost of installation Able to perform weight bearing scans Easy access door for step-in access to patients Reduced radiation dosage compared to regular CT Installation at prefered locations for convenient imaging Importance of Weight Bearing Imaging X-rays / CT scans do not adequately capture the frontal plane Allows evaluation of deformities that involve external rotation, or rotation of metatarsals “The image on the left from a non-weight-bearing exam fails to provide a clear view of bone impingement revealed in the OnSight weight-bearing exam on the “CubeVue, the pedCAT weight bearing CT imaging system’s custom visualization software, allows physicians to create oblique and frontal-plane images of varying angles and thicknesses from the weight bearing CT data.” The Future Lower radiation dosage Lower cost for general public Wider access Any Questions?
