EOS Orthopedic Imaging

A radically new vision of orthopedic imaging.

Why guess when you can see. measure. analyse?

With EOS, radiologists and orthopedists can now for the first time, have a full view of their patient's skeleton: life-size, naturally weight-bearing, in 3D, from all angles. All this with a drastic reduction of radiation exposure. All this with a faster workflow. All this thanks to a Nobel-Prize invention.

How Does It Work?

EOS captures simultaneous frontal and lateral head-to-toe images of patients in the upright, weight bearing position.

EOS technology uses of two perpendicular X-ray beams collimated in two very thin, horizontal, fan-shaped beams and two Nobel Prize winning technology detectors.
Fan-beam x-rays and detectors are mounted on a C-arm and scan all or part of the patient's body. This allows for frontal and lateral X-rays of a patient to be carried out simultaneously. Two variable gain detectors detect line by line an extremely high contrast digital radiograph, while the dose administered to the patient does not exceed a dose equivalent to the exposure that results from a few transatlantic flights.


Unequalled readiation exposure reduction

With medical imaging usage increasing over the last 25 years, reducing the patient's exposure to X-ray doses has been a top priority of the medical imaging community for several years.

EOS is showing the way: The Nobel-Prize technology of EOS allows its dosage to be 6 to 9 times less than CR Systems and more than 100 times below that of a 3D CT scan.

Because EOS Nobel-Prize winning detector's automatic gain control, paired with its ability to reject scattered X-rays, gives radically enhanced image contrast performance at a very reduced dose. Only EOS can produce such an image at such doses, bringing the ALARA (As Low As Reasonably Achievable) principle to levels never met before.

High patient throughput

The patient stands or sit inside the EOS booth and the proprietary detector provides a whole, weight-bearing body image in less than 20 seconds for an adult and less than 15 seconds for a child.

While the patient stands or sits, a vertical drive mechanism inside EOS moves a C-arm down the entire height of the patient, or any desired subset of his length. 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.

In only twenty seconds or less, two full body digital radiographs are taken. No stitching, no cassette handling: EOS not only improves accuracy but also saves technologist and patient waiting time during busy clinics, with total exam cycle below 4 minutes even for complex spine exams.
