Low dose radiation system provides 2D and 3D images of the spine


An innovative system that creates 2D and 3D images of the spine and other body parts while dramatically reducing the amount of radiation exposure is being used by Norton Leatherman Spine specialists to collect more accurate diagnostic images with less of risks.

Patients with scoliosis and other conditions typically need multiple images to track the progression of their condition and, if surgery is required, to plan the procedure and monitor outcomes.

With a $300,000 grant from the Norton Children’s Hospital Foundation and support from the PACCAR Foundation, the EOS system was recently installed at the Norton Healthcare Pavilion in downtown Louisville.

EOS provides 50% to 85% less radiation than traditional X-rays and 95% less radiation than basic CT scans. EOS achieves the combination of low dose and high definition by narrowing the radiation into narrow, parallel beams.

Reducing radiation exposure is especially beneficial for children requiring frequent imaging exams. The Micro Dose feature further reduces radiation exposure, providing full frontal and lateral pediatric images of the spine at a dose equivalent to just one week of natural radiation.

“We are especially pleased to have installed this system, as it demonstrates our commitment to patient-centric solutions and patient health and safety,” said John R. Dimar, MD, orthopedic spine surgeon at Norton Leatherman Spine.

Unlike many other imaging technologies, EOS can capture images when the patient is standing and weight bearing, rather than lying down. The stance position allows physicians to more accurately assess posture and better understand the relationship between the spine, pelvis, and lower extremities.

The machine is height adjustable and patients can stand, sit, bend, squat, or sit, depending on the assessment area. 3D models of the patient’s unique anatomy allow for more accurate diagnoses and can be used to develop personalized surgical plans.
