EOS Imaging System

OHSU is one of only two Oregon hospitals with the EOS Imaging System, which offers advanced scanning for pediatric and adult spine conditions, including scoliosis. Compared with other imaging systems, benefits include:

  • Significantly better image quality.
  • Less radiation than a traditional X-ray or CT scan.
  • Full-body images that allow a better understanding of how your bones relate to one another.
  • 3D images that help in surgical planning available.
  • High quality weight-bearing images that provide an understanding of how the spine, hip and knee compensate for injuries and conditions.
  • Available to both children and adults.

How it works

The EOS Imaging System takes a low-dose image from the front and side at the same time. It can take full-body images or focus on a specific body part. A micro-dose option is ideal for follow-up scans. Images can be taken with the patient standing, bending, squatting or sitting.

What to expect

  • You will be guided to the EOS scanner — a large, L-shaped X-ray machine.
  • A technician will help you get in the right position.
  • The technician will run a 30- to 40-second laser positioning process to make sure you’re in the right position.
  • Scans take about 15 seconds for children and 20 seconds for adults.

Why it matters

  • Better images help your doctors make a more precise diagnosis so they can better plan treatment.
  • Less radiation means less risk of future health problems, especially for those with conditions such as scoliosis that need regular scans, often over years.
  • Faster images mean more comfort and convenience for you.
  • OHSU has the only EOS system for adult spine patients between Seattle and San Francisco.

For patients

Talk with your care team at the OHSU Spine Center or Doernbecher Children’s Hospital about whether the EOS system is a good option for you or your child.
