Queenslands first EOS Imaging System


EOS imaging System at SCR Southport by Dr Yu Ming Tang


South Coast Radiology is proud to be the first imaging provider in QLD to install an EOS imaging system. The system was installed into our Southport rooms with first patients imaged on Tuesday 26th April with great success.


What is the EOS:

EOS captures whole body images of a standing patient in a single scan without any stitching or vertical distortion. Frontal and lateral digital images of any length can be obtained simultaneously, with outstanding image quality.

EOS uses two perpendicular X-ray beams collimated in two very thin, horizontal, fan-shaped beams along with two detectors born out of Nobel Prize-winning technology.

Fan-beam X-rays and detectors are mounted on a C-arm and scan all or part of the patient’s body as needed. This allows for frontal and lateral X-rays of a patient to be carried out simultaneously.


Dose Reduction with EOS:

With medical imaging usage increasing over the last 25 years, reducing the patient’s exposure to X-ray dose has been a top priority of South Coast Radiology for several years. The community is becoming increasingly aware of the risks of over exposure to radiation.

The automatic adjustment of the gain of the detector allows a radical improvement in contrast performance at a very low dose. Two variable gain detectors detect an extremely high contrast digital radiograph line by line, while the dose administered to the patient is less than or equivalent to the exposure that results from few transatlantic flights.

With the addition of EOS to South Coast Radiology’s long list of cutting edge equipment we are leading the way.


What should patients expect?

The patient stands or sits inside the EOS booth, and then an X-ray of the whole body is taken in less than 20 seconds for an adult and less than 15 seconds for a child.

The EOS exam is performed by a linear scan of the C-arm and two very fine X-ray beams. The C-arm supports two separate imaging systems capable of simultaneously capturing both frontal and lateral images. Digital images are immediately available on the 2D workstation.


Our EOS experience so far:

EOS is becoming increasingly well known amongst the spinal community – surgeons, chiropractors, osteopaths and even well informed patients. Before our installation of the EOS on the Gold Coast, Queensland patients were travelling via plane to Sydney or Melbourne on a regular basis to monitor their scoliosis. This was especially true for younger patients with parents concerned about the long term effects of continual radiation exposure from traditional x-rays. With the EOS reducing the radiation exposure by up to 9 times compared to regular x-ray it mean patients can continue to have EOS scans with decrease risk of adverse affects caused by radiation.

The majority of patients receiving imaging for scoliosis are children or young adults where radiation reduction is extremely important. In these cases some parents are willing to go to extreme lengths to protect their children from unnecessary radiation which means travelling interstate.

We believe the addition of the EOS to South Coast Radiology will have a positive effect on the Gold Coast and surrounding community giving patients and their specialists a local choice for low dose full weight bearing spinal imaging.
