Device Story
System for acceptance, transfer, display, storage, and digital processing of 2D X-ray images; provides interactive 2D/3D measurement tools. Inputs: 2D X-ray images from EOS Imaging EOS System. Operation: User identifies anatomical landmarks on frontal/lateral X-rays; system uses linear regression and a priori database (parametric models) to generate 3D bone structure models. Operator manually deforms 3D model to match X-ray contours using linear least squares estimation. Output: 3D skeletal models, angle/length measurements. Used in clinical settings by physicians/technologists to aid analysis of spine/lower limb deformities. Benefits: Enables 3D assessment of skeletal alignment from 2D images.
Clinical Evidence
Bench testing only. Accuracy and precision of automatic measurements computed from 3D lower limb models validated using clinical X-ray images. Results demonstrate equivalent performance to conventional measurement methods on native X-ray images.
Technological Characteristics
Supports DICOM 3.0. Runs on off-the-shelf hardware (Dell Precision) with Windows XP. 3D reconstruction uses parametric models of tibia/femur/spine derived from a priori databases of clinical descriptors and CT volumes. Deformation uses linear least squares estimation. Connectivity via DICOM query/retrieve.
Indications for Use
Indicated for musculoskeletal radiology and orthopedics in pediatric (spine: 7+ years; lower limb: 15+ years for 3D package) and adult populations. Used for PACS functions (acceptance, transfer, display, storage, processing) of 2D X-ray images. 3D tools aid analysis of scoliosis (Cobb's angle <= 50 degrees) and lower limb alignment/deformities. Contraindicated for individual vertebral/bone abnormality assessment and scoliosis patients with Cobb's angle > 50 degrees.
Regulatory Classification
Identification
A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

### Dear Mr. Smith:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); medical device reporting (reporting of
{7}------------------------------------------------
medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Parts 801 and 809), please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (301) 796-5450. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportalProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.
You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 796-7100 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.

Device Name: sterEOS Workstation
The sterEOS Workstation is intended for use in the fields of musculoskeletal radiology and orthopedics in both pediatric and adult populations as a general PACS device for acceptance. transfer, display, storage, and digital processing of 2D X-ray images of the musculoskeletal system including interactive 2D measurement tools.
When using 2D X-ray images obtained with the EOS Imaging EOS System (K071546), the sterEOS Workstation provides interactive 3D measurement tools:
- to aid in the analysis of scoliosis and related disorders and deformities of the spine in adult patients as well as pediatric patients 7 years and older. The 3D measurement tools include interactive analysis based on a model of bone structures derived from an a priori image data set from 175 patients (91 normal patients, 47 patients with moderate idiopathic scoliosis and 37 patients with severe idiopathic scoliosis), and dry isolated vertebrae data. The model of bone structures is not intended for use in patients with a Cobb's angle > 50 degrees and is not intended for use to assess individual vertebral abnormalities.
- to aid in the analysis of lower limbs alignment and related disorders and deformities ﺍ based on angle and length measurements. The 3D measurement tools include interactive analysis based either on identification of lower limb alignment landmarks or as for the spine, on a model of bone structures derived from an a priori image data set. The model of bone structures is not intended for use to assess individual bone abnormalities. The 3D package including model-based measurements and torsion angles is indicated only for patients 15 years or older. Only the 2D/3D ruler is indicated for measurements in patient vounger than 15 years old.
