How it works
EOS is an advanced X-ray system that captures high-resolution images while you are standing in a natural, weight-bearing position. It captures simultaneous front and side images in a single scan.
EOS imaging is used to assess:
- Spine conditions, including scoliosis
- Hip and knee alignment
- Posture and overall skeletal balance
- Joint replacements
- Pre- and post-surgical alignment
Weight-Bearing Biplanar X-ray Imaging
Biplanar imaging captures front and side X-Ray images at the same time while you are in a natural, weight-bearing position. This allows practitioners to assess posture and alignment under normal load.
You stand in a natural position on an open gantry while the images are acquired.
Optional 3D Modelling with sterEOS
sterEOS can create 3D models and reports from suitable images taken during an EOS scan. These are only provided when clinically requested and available. The modelling uses front and side images captured during an EOS scan to create 3D reconstructions.
These outputs support measurements and review of the spine or lower limbs. A 3D model is not produced automatically or included with every EOS scan.
Research into EOS biplanar imaging explains how the images are captured and discusses the technique’s benefits and limitations.
Conditions and assessments supported by EOS
EOS imaging supports assessment of:
What to expect
EOS uses low-dose X-rays to capture long-length images while you are in a weight-bearing position. Its lower radiation exposure can be beneficial when repeated imaging is clinically required, such as for some scoliosis and orthopaedic monitoring.
In a study of 97 patients, EOSedge reported lower radiation measures than standard digital radiography for the pelvic and hip views assessed.
Day of the scan
Follow the instructions provided to you when booking. You may be asked to change into a gown and remove metal items such as watches, earrings and chains.
During the examination, you will stand or sit in the open imaging cabin and remain still while the images are taken.
EOS is an X-ray examination. Tell your referring healthcare professional and the Lumus Imaging team if you are or may be pregnant. See What to Expect for more information about your appointment. Healthdirect Australia also provides information about X-rays and pregnancy.

Frequently asked questions
Do I need a referral for EOS imaging?
Yes. A referral is required for EOS imaging. When booking, confirm that an EOS x-ray is requested and confirm the Lumus Imaging location where your EOS examination will take place.
Is EOS the same as a standard X-ray?
EOS is a specialised form of X-ray imaging. It captures simultaneous front and side views while you are in a functional weight-bearing position, providing information about posture and alignment under load.
Does every EOS scan include a 3D model?
No. A sterEOS 3D model is only produced when requested by your referring clinician and if it is available at the clinic where you have your scan. Please check with the Lumus Imaging staff when you make your booking.
