EOS Imaging System


The EOS Imaging System is a low-dose, 3D imaging system that provides images of patients in natural standing positions. The technology produces high-quality, detailed images while using a significantly lower radiation dose than a general radiography X-ray, enabling clinicians to make a more informed diagnosis and create individualised treatment plans for children with musculoskeletal disorders.

By imaging patients in a weight-bearing standing position, EOS is able to capture natural posture and the interaction between joints and the rest of the musculoskeletal system, particularly the spine, hips and legs.


Reduced radiation dose:

  • EOS delivers a radiation dose that is 6 to 9 times less than a standard X-ray film and 20 times less than basic computed tomography (CT) scans.
  • Reducing radiation dose is particularly beneficial for paediatric patients that need to be imaged frequently, and those with spinal deformities such as scoliosis.
  • Better diagnostics and image accuracy:
  • 3D weight-bearing images of patients in an upright, standing position provide the most accurate view of the spine and lower limbs, enabling physicians to evaluate balance and posture and analyse 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, providing an accurate view of the musculoskeletal system that is essential to diagnosis and treatment planning.


What to do before an EOS examination

There is no preparation required for an EOS examination.

At Southern Radiology you do not require an appointment for an EOS examination, however we require a written referral or request from a medical practitioner before undertaking any examinations. Please ensure you bring your referral with you to your appointment.

If you are or may be pregnant it is imperative to advise our staff of this prior to your examination.

For all examinations we are that you bring along any previous imaging you have of the area under investigation.

Please bring your Medicare or Department of Veterans Affairs card.


What happens during an EOS examination?

The exact procedure for any Medical Imaging examination depends on what is being imaged and why.

Although there will be slight variations in what you can expect when you attend a Southern Radiology practice for an EOS examination, as a general guideline:

  • You will need to register with our secretarial staff upon arrival.
  • You may be required to fill out some safety and medical history paperwork before we can commence your test.
  • You may be asked to change into a gown.
  • Your attending Radiographer will explain all aspects of your examination to you.
  • Your consent will be sought prior to commencing the examination.
  • You will be asked to stand or sit down. This will depend on the area being examined.
  • You will be asked to remain still for the EOS examination, which may take anything from 5 to 20 seconds.
  • You will have two or more views of each body part being imaged.


The duration of your visit includes the time it takes to:

  • Register your details;
  • Complete safety and medical history paperwork;
  • Prepare for your examination;
  • Complete your EOS examination;
  • Collect your films.
  • An EOS examination typically only takes 5 to 20 seconds but we advise you to check with our friendly secretarial staff on wait times when you arrive at the practice. Wait times vary with the number of patients attending the practice at the time, as well as the clinical status of these patients.


An EOS examination, like an X-ray, is a form of ionising radiation. However, EOS uses 6 to 9 times less radiation than a standard X-ray film and 20 times less radiation than computed tomography (CT).

The combination of our experienced Radiographers and the use of EOS ultra-low-dose technology assures that radiation doses are kept to a minimum.
