Intended Use
The GE Lunar enCORE software used on the GE Lunar bone densitometer total body scan estimates the Resting Metabolic Rate (RMR) in the male or female population age 18 and older. The data can be displayed in user-defined statistical formats and trends. The GE Lunar enCORE software used on the GE Lunar bone densitometer total body scan estimates the Relative Skeletal Muscle Index (RSMI) in the male or female population age 18 and older. The data can be displayed in user-defined statistical formats and trends. The MirrorImage function in the enCORE software used on the GF. Lunar DXA bone densitometers can be used to estimate the total body composition and bone mineral density (BMD) when regions of the body are outside of the scan window by using scanned data from the corresponding region(s) on the opposite half of the body.
Device Description
enCORE is the software is used by the series of GE Lunar DXA bone densitometers. Release 14 of the enCORE software (enCORE 14 or enCORE 14.xx) includes some feature enhancements. The software will calculate Resting Metabolic Rate (RMR) and Resting Skeletal Muscle Index (RSMI) using existing scan data. The calculations of RMR and RSMI do not require any changes to the bone densitometer nor does it require additional scanning or radiation exposure beyond the Total Body scans. Additionally, the enCORE software can utilize a MirrorImage function, which estimates Body Composition values using scanned data from the opposite side of the body if the patient does not fit entirely within the scan window. The GE Lunar DXA bone densitometers measure the bone mineral density (BMD), lean and fat tissue mass and calculate derivative values of bone mineral content (BMC), area, soft tissue mass, regional soft tissue mass, total soft tissue mass, fat free mass, regional/total soft tissue mass ratio, % fat, region % fat, total body % fat, Android % fat, Gynoid % fat, Android/Gynoid ratio (A/G ratio) and Body Mass Index (BMI).
More Information

Not Found

No
The summary describes calculations based on existing scan data and a "MirrorImage function" which estimates values from the opposite side of the body. There is no mention of AI, ML, training data, or performance metrics typically associated with AI/ML algorithms.

No
The device estimates RMR and RSMI and measures body composition and bone density; it does not explicitly state any therapeutic use or function.

No

The primary function of the device described is to estimate various body composition parameters and metabolic rates (RMR, RSMI) for informational and statistical purposes, not to diagnose a disease or condition. While bone mineral density (BMD) is a measurement related to osteoporosis, the document emphasizes estimation and trending of body composition, not a diagnostic claim for specific diseases. The "Intended Use" section mentions "estimates" and "data can be displayed in user-defined statistical formats and trends," which aligns with general health assessment rather than medical diagnosis.

No

The device is described as software used on GE Lunar DXA bone densitometers, which are hardware devices that perform x-ray transmission measurements. The software processes data from this hardware, indicating it is a component of a larger hardware system, not a standalone software-only device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The GE Lunar enCORE software and bone densitometer measure bone mineral density and body composition using x-ray transmission measurements of the total body. This is a non-invasive imaging technique performed directly on the patient, not on a sample taken from the patient.
  • Intended Use: The intended uses described (estimating RMR, RSMI, and body composition/BMD) are based on analyzing the data acquired from the in-vivo scan, not from testing a biological sample.

Therefore, the device falls under the category of medical imaging devices, not in vitro diagnostics.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The Resting Metabolic Rate (RMR) and Relative Skeletal Muscle Index (RSMI) are calculated using scan data collected using the Body Composition software option. There is no change to the scan performed.

The MirrorImage function allows Total Body Composition values to be estimated for patients who are larger than the scan window. The MirrorImage function uses existing scan data. There is no change to the scan performed.

The following quality assurance measures were applied to the development of the product:

  • Risk Analysis
  • Requirements Reviews
  • Design Reviews
  • Testing on unit level (Module verification)
  • Integration testing (System verification)
  • Performance testing (Verification)
  • Safety testing (Verification)
  • Simulated use testing (Validation)

It is concluded that the added features do not impact safety and effectiveness of the enCORE software or the GE Lunar DXA Bone Densitometers in comparison to the predicate device. The enCORE 14 Software Release for the GE Lunar DXA Bone Densitometers with the RMR, RMSI and MirrorImage indications is substantially equivalent to the predicate device.

Dear Ms. Dwyer:

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

4

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/ReportaProblem/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.
