No
The document describes standard image processing algorithms and comparisons to reference databases, with no mention of AI or ML techniques.
No
The device measures bone mineral content, density, and body composition for diagnostic and comparative purposes, but it does not treat or cure any medical condition.
Yes
The device measures BMC, BMD, and body composition using dual energy x-ray absorptiometry and compares these measurements to a database of reference values. This process is used to assess the patient's condition, which aligns with the definition of a diagnostic device. The "Intended Use / Indications for Use" section explicitly states that the software provides a comparison of measured variables useful for "comparative purposes," implying diagnostic assessment. Furthermore, it estimates periprosthetic BMD "pre- and post-surgery," indicating its role in evaluating surgical outcomes which is a diagnostic function.
No
The device is described as software that runs on GE Lunar DXA bone densitometers, which are hardware devices that perform dual energy x-ray absorptiometry. The software processes data from this hardware.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD definition: In vitro diagnostics are tests performed on samples such as blood, urine, or tissue that have been taken from the human body. They are used to detect diseases, conditions, or infections.
- Device function: The description clearly states that this device is a software used on GE Lunar DXA bone densitometers. These densitometers use dual energy x-ray absorptiometry to measure bone mineral density and body composition directly on the patient.
- No sample analysis: There is no mention of analyzing samples taken from the body. The measurements are performed in vivo (within the living body).
Therefore, the function and method of operation of this device fall outside the scope of an In Vitro Diagnostic.

Intended Use / Indications for Use
The enCORE version 16 for 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 optional "Complete Pediaric" software option mineral content (BMC), bone nineral density (BMD) and body composition (lean body mass and fat mass) in patients from birth to 20 years of age. The software provides a comparison of measured variables obtained by dual energy x-ray absorpionery to a database of reference values for patients 5-19 years of age. These data can be used for comparative purposes at the sole discretion of the software does not provide a reference population for comparative purposes for patients younger than 5 years of age.
Optional Orthopedic software estimates periprosthetic BMD of an orthopedic hip or knee implant (pre- and post-surgery).

Device Description
enCORE software is used on GE Lunar DXA bone densitometers. Release 16 of the enCORE software (enCORE 16 or enCORE 16.xx) includes some feature enhancements. The software will now expand upon its previously cleared pediatric indication (K001812) by providing a "Complete Pediatric" software that can measure the bone mineral content (BMC), bone mineral density (BMD) and body composition (lean body mass and fat mass) in patients from birth to 20 years of age. The software will also provide a comparison of measured variables obtained by dual energy x-ray absorptiometry to a database of reference values for patients 5-19 years of age. The software will also expand its previously cleared orthopedic hip indication (K972517) to include estimates of the BMD of the knee before and after joint implant.
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).
Mentions image processing
The enCORE version 16 Software Release for the GE Lunar DXA Bone Densitometers employs the same fundamental scientific technology as its predicate device, which is dual-energy x-ray absorptiometry using a PC based image processing algorithm running on a Microsoft Windows operating system.
