EOS imaging

Medical imaging system for 3D modeling of the skeletal system

EOS imaging system in use

EOS imaging is a medical imaging system that provides low-dose, full-body, and three-dimensional (3D) images of patients in a natural standing or seated position. This technology is particularly useful in the fields of orthopedics and radiology for assessing musculoskeletal disorders, including scoliosis, leg length discrepancies, and other deformities.

Technology

The EOS imaging system utilizes a combination of X-ray technology and advanced software to create detailed 3D models of the skeletal system. Unlike traditional X-ray systems, EOS imaging captures images using a low-dose radiation technique, which significantly reduces the exposure to ionizing radiation for patients.

The system consists of two perpendicular X-ray beams that simultaneously capture frontal and lateral images of the patient. These images are then processed by specialized software to generate a 3D model of the patient's skeletal structure. This capability allows for precise measurements and assessments of bone and joint alignment, which are critical for diagnosing and planning treatment for various orthopedic conditions.

Applications

EOS imaging is widely used in the diagnosis and management of spinal deformities such as scoliosis, kyphosis, and lordosis. It is also employed in evaluating lower limb alignment and planning for total hip arthroplasty and total knee arthroplasty.

The system's ability to provide accurate 3D models aids in preoperative planning and postoperative assessment, ensuring better outcomes for patients undergoing orthopedic surgeries. Additionally, the low-dose nature of the imaging makes it suitable for repeated use, which is often necessary in the monitoring of progressive conditions like scoliosis.

Advantages

One of the primary advantages of EOS imaging is its low radiation dose, which is particularly beneficial for pediatric patients and those requiring frequent imaging. The system's ability to produce full-body images in a single scan reduces the need for multiple exposures, further minimizing radiation risk.

The 3D modeling capability of EOS imaging provides a comprehensive view of the patient's anatomy, allowing for more accurate diagnosis and treatment planning. This is especially important in complex cases where precise anatomical information is crucial.

Development and History

EOS imaging was developed by the French company Biospace med, which was later acquired by EOS imaging SA. The technology is based on the work of Nobel Prize-winning physicist Georges Charpak, who contributed to the development of the low-dose X-ray detection system used in EOS.
