EOS X-Ray Imaging System

What is EOS?


The EOS Imaging System is a low-dose, 3-D imaging system that scans your child standing up. An EOS scan shows us your child’s natural, weight-bearing posture and allows us to see the interaction between the joints and the rest of the musculoskeletal system, particularly the spine, hips and legs.

What are the benefits of EOS imaging?


• EOS imaging uses an ultra-low dose of radiation to provide extremely detailed, high-quality images. It uses a significantly lower radiation dose than a general radiography X-ray. With EOS scans, we can make more informed diagnoses and create individualized treatment plans for children with musculoskeletal disorders.

• We take every safety precaution and have set the standards for reducing children’s exposure to radiation across all imaging tests and procedures. EOS technology is yet another tool that enables us to provide the best imaging services while reinforcing our commitment to safety and low-dose imaging options for our patients.

• EOS delivers a radiation dose that is two to three times less than a general computed radiography X-ray and 20 times less than basic computed tomography (CT) scans.

• Reducing radiation dose is particularly beneficial for children who need to be imaged frequently, such as children with spinal deformities like scoliosis. Children’s Hospital of Philadelphia (CHOP) was the first institution in the U.S.
to introduce the use of “EOS micro-dose” in the imaging of these children. Micro-dose uses one-third of the standard EOS radiation dose, further reducing the radiation exposure for children who require frequent imaging.

• Better diagnostics and image accuracy :

• 3-D weight-bearing images of children in an upright, standing position give us the most accurate view of the spine and lower limbs. Physicians can better evaluate balance and posture and analyze the bones, joints and ligaments from multiple angles.

• This type of imaging enables us to view all areas of the body with one image, rather than stitching together multiple images. It gives us an accurate view of the musculoskeletal system that is essential to diagnosis and treatment planning.
