EOS offers 50% to 85% less radiation than traditional X-rays and 95% less radiation than basic computed tomography (CT) scans.
An innovative system that creates 2D and 3D images of the spine and other parts of the body while dramatically reducing the amount of radiation exposure is being used by Norton Leatherman Spine specialists to collect more precise diagnostic images with less risk.
Patients with scoliosis and other conditions typically need multiple images to follow the progression of their condition and, if surgery is needed, to plan the surgery and monitor results.
With the help of a $300,000 grant from the Norton Children’s Hospital Foundation with support from the PACCAR Foundation, the EOS system recently was installed at Norton Healthcare Pavilion in downtown Louisville.
EOS offers 50% to 85% less radiation than traditional X-rays and 95% less radiation than basic computed tomography (CT) scans. EOS achieves the combination of low dose and high definition by narrowing the radiation into narrow, parallel beams.

A rich history of innovative spine care and a worldwide reputation for excellence.
Reducing radiation exposure is particularly beneficial for children requiring frequent imaging. The Micro Dose feature further reduces radiation exposure, offering pediatric full-spine images from the front and side at a dose that’s equivalent to only a week’s worth of natural radiation.
“We are particularly excited to have this system installed, as it demonstrates our commitment to patient-focused solutions, as well as patients’ health and safety,” said John R. Dimar, M.D., orthopedic spine surgeon with Norton Leatherman Spine.
Unlike many other imaging technologies, EOS can capture images while the patient is upright and bearing weight, rather than lying down. The weight-bearing position allows physicians to evaluate posture more accurately and better understand the relationship between the spine, pelvis and lower limbs.
The machine is adjustable for height, and patients may stand, sit, bend, squat or sit, depending on the area of evaluation. 3D models of the patient’s unique anatomy make for more precise diagnoses and can be used for developing customized surgical plans.
