Hutchinson Campus welcomes state-of-the-art EOSedge system X-ray imaging machine

Montefiore is now one of the first academic medical centers in the region to have this new low-dose, high-quality imaging machine for orthopedic care. It enables rapid acquisition of high-quality images with 3D capability to aid in surgical planning while greatly reducing radiation exposure to our patients.

EOSedge is a state-of-the-art, low-dose 2D/3D X-ray imaging system used for the management of orthopedic conditions. The exam lets our physicians see the interaction between joints and the rest of the musculoskeletal system, particularly the spine, hips and legs. The system uses two X-ray beams to scan the patient, creating two high-quality images of either the entire body or a specific region of the body. Images can be used to generate 3D models and measurements, which provide a three-dimensional understanding of a patient’s medical condition and its complexity. This allows our doctors to make an accurate evaluation and tailor treatment plans for each patient. The digital X-ray images are immediately available for review after the scan, which takes an average of 10 to 25 seconds. The total exam time takes approximately four minutes, including exam preparation. For some patients, 3D information may be requested by the doctor, in which case a trained EOS radiology technician will generate a 3D model using a special computer program. It can take up to three days for the 3D data to be generated.

Every precaution is taken to reduce radiation exposure across all imaging tests and exams. EOSedge is yet another tool that enables us to provide the best imaging services while reinforcing our commitment to safety and low-dose imaging options for our patients. The machine also has a unique setting called Flex DoseTM that adjusts the amount of radiation a patient receives along the body. This setting minimizes exposure in areas of the body whenever possible, while still delivering the high-resolution images needed for our doctors to make treatment decisions. Reducing dose is particularly beneficial for pediatric patients who are more sensitive to the cumulative effects of radiation. For this reason, EOSedge can reduce radiation exposure to even lower levels thanks to a setting called Micro Dose, which emits even less radiation than a standard exam (equivalent to about a day of natural background radiation on Earth) and is still capable of producing 3D models and measurements for assessing global skeletal deformities in follow-up pediatric examinations.

With traditional imaging techniques, patients often need to lie down or hold an uncomfortable pose to get the best image. With EOSedge, patients are able to be scanned while standing or in a seated position, which allows the doctor to examine the natural posture, as well as the ways that the spine, hips, and lower limbs are positioned in relation to one another. When necessary, 3D information can be captured in an upright, weight-bearing position. And because orthopedic disorders are three-dimensional conditions, it’s important that doctors are able to examine images in 3D as well.

In addition to reduced radiation dose, clear images and convenient exams, the unique perspective provided by EOSedge allows doctors to get a more complete picture of a patient’s condition to provide a precise diagnosis and gather detailed information should surgical interventions become necessary. The 3D models and software can assist surgeons by helping them to plan—and, in some cases, even simulate—spine, hip or knee surgical procedures to better understand how they will be performed. Ultimately, EOSedge aligns with our mission to provide exceptional patient care by delivering low-dose exams, high-quality images and 3D information when needed.
