Intended Use

The enCORE 14 Software Release for the GE Lunar DXA Bone Densitometers is intended for medical purposes to measure bone density, bone mineral content, and fat and lean tissue content by x-ray transmission measurements through the bone and adjacent tissues.

Device Story

enCORE 14 software operates on GE Lunar DXA bone densitometers; processes existing total body scan data to calculate Resting Metabolic Rate (RMR) and Relative Skeletal Muscle Index (RSMI). Includes MirrorImage function to estimate body composition and BMD for patients exceeding scan window dimensions by mirroring data from the opposite side of the body. Used in clinical settings by healthcare professionals; output displayed in statistical formats and trends. Assists clinicians in assessing body composition and metabolic status. No changes to hardware, radiation exposure, or scan protocols required.

Clinical Evidence

No clinical data required; substantial equivalence supported by bench testing, including risk analysis, requirements/design reviews, module verification, system integration testing, and simulated use validation.

Technological Characteristics

Software-based feature enhancement for existing DXA bone densitometers. Utilizes x-ray transmission measurements. No hardware modifications. Connectivity via existing densitometer platform. Quality assurance per standard design control processes.

Indications for Use

Indicated for estimation of Resting Metabolic Rate (RMR) and Relative Skeletal Muscle Index (RSMI) in males and females age 18 and older. Also indicated for estimation of total body composition and bone mineral density (BMD) via MirrorImage function when body regions fall outside the scan window by using data from the opposite body half.

Regulatory Classification

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).

Intended Use:

Determination of

Substantial Equivalence:

The enCORE 14 Software Release for the GE Lunar DXA Bone Densitometers is intended for medical purposes to measure bone density, bone mineral content, and fat and lean tissue content by x-ray transmission measurements through the bone and adjacent tissues.

The enCORE 14 Software Release for GE Lunar DXA Bone Technology: Densitometers employs the same fundamental scientific technology as its predicate device.

## Summary of Non-Clinical Tests:

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

#### 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.
