EOS Ultra Low Dose 2D/3D Imaging System


St. Mary’s Medical Center is the first hospital in Florida to obtain this unique, ultra low dose orthopedic imaging system which allows for simultaneous bilateral long length images (full body or localized) in either a standing or seated position. 

EOS provides 3D imaging of the skeleton and automatically calculates a broad range of clinical parameters essential to diagnosis and surgical planning.  This technology was developed from Nobel Prize-winning technology and used in over 150,000 procedures to date across North America, Europe and Australia.


EOS slot scanner takes Frontal and Lateral X-ray images of patients in either standing or seated weight-bearing positions.   

  • High energy particle detector enables imaging to be performed at lower dose with enhanced image detail and contrast—and without the vertical distortion of long length films and other digital imaging systems
  • Images delivered at true life size for more informed diagnosis

SterEOS workstation creates full length 3D rendering of skeletal anatomy and calculates over 100 clinical parameters for spine, pelvis and lower limb orientation for pre- and post-operative planning

  • Enables creation of complete patient report including images and charts
  • User-friendly interface for step-by-step guidance through 3D modeling process


Ultra Low Dose Imaging

Radiation exposure from medical imaging can carry long-term risks: study in New England Journal of Medicine suggests that as many as 2% of cancers cases in the U.S. may be tied to growing use of CT scans. The ultra low dose with EOS is documented to be up to nine times less than conventional computed radiography systems and up to 20 times less than a CT scan.

Unique Full Body Imaging

Prior to EOS, clinicians often had to “stitch” together multiple smaller images to approximate full picture of target anatomy; this process could be particularly problematic for complex orthopedic conditions, like spinal disorders. EOS captures whole body images in a single scan without stitching or vertical distortion, providing true size images in 1:1 scale for highly accurate surgical planning measurement.  For the first time, Frontal and Lateral digital images up to 175cm may be obtained simultaneously.

3D Imaging

Because many orthopedic conditions occur across multiple planes of the body, 3D renderings offer an accurate representation that clinicians can view and analyze from multiple angles. EOS’s unique 3D imaging gives weight-bearing 3D model of the spine and lower limbs, enabling the calculation of additional clinical parameters. It is the only system that enables physicians to globally evaluate patient’s balance and posture in a natural upright position.  

Faster Imaging

Proprietary detector produces a full or partial body, weight-bearing image in less than 20 seconds for an adult and less than 15 seconds for a child. Full body imaging negates needs to stitch together several partial images. EOS enables total exam cycles below four minutes for even complex spine exams – much faster than traditional X-ray devices.



Research shows spinal alignment is impacted by pelvic and lower limb position; full body imaging enables physicians to take full musculoskeletal alignment into consideration for more appropriate diagnosis and surgical planning.  Complex spinal deformity, such as scoliosis, is three dimensional and requires correction across three planes of the body; 3D imaging enables a more complete picture of the deformity to help plan complicated surgical treatments.

Lower Limb (Hip/Knee)

Planning for hip, knee and other lower limb surgeries involves careful assessment of musculoskeletal alignment; if the orientation of joint prosthesis is off even slightly, for example, it could let to a greater risk of complications such as implant failure. Research shows 3D modeling with the EOS system can provide more accurate measurements of several key parameters used to evaluate lower limb alignment, such as tibial (shin bone) and femoral (thigh bone) length or frontal and lateral (side) knee angulations.


Ultra low dose makes EOS advantageous for the pediatric population, particularly for children who have been diagnosed with scoliosis and are imaged frequently to monitor disease progression.  Research shows effective dose of EOS imaging was seven times lower than that of full-field digital radiography for scoliosis follow-up. Typically adolescent scoliosis patients much undergo scans every 3-6 months, up to 20+ over the course of treatment. Recent study in European Radiology also supports 3D imaging in adolescents for more precise assessment of lower limb alignment compared to traditional 2D imaging.  


EOS imaging is the developer of the EOS Imaging System and is a leader in orthopedic imaging, dedicated to promoting a more holistic approach to musculoskeletal care with a lower imaging dose. The company has corporate headquarters in Cambridge, Mass., USA, and Paris, France, as well as an office in Montreal, Canada.
