The summary does not mention AI, ML, or related terms, and the description focuses on standard image processing and correlation with a predicate device.
No
This device is software used for analysis and estimation of bone mineral density around hip implants, not for treating or diagnosing a disease or condition.
Yes
The device estimates Bone Mineral Density (BMD), which is a measurement used to assess bone health and diagnose conditions like osteoporosis, thus serving a diagnostic purpose.
Yes
The device is described as "accessory software option" for an existing Bone Densitometer system and its function is solely software-based analysis of data acquired by the hardware.
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 EXPERT-XL Orthopedic Hip Acquisition and Analysis Software works with a Bone Mineral Densitometry system. This system uses imaging (Bone Mineral Densitometry) to measure bone density in vivo (within the living body), specifically around an orthopedic hip implant.
- No Sample Analysis: The description does not mention the analysis of any biological samples taken from the patient. The measurement is performed directly on the patient's body using the densitometry system.
Therefore, since the device operates by analyzing images acquired directly from the patient's body rather than analyzing samples taken from the body, it falls outside the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The EXPERT-XL Orthopedic Hip Acquisition and Analysis Software is used with the EXPERT-XL Bone Mineral Densitometry system. This new software feature allows for estimation of periprosthetic BMD of an orthopedic hip implant in sub-regions called Gruen zones. These zones are a typical radiographic labeling technique for orthopedic hip implants.
The EXPERT-XL Orthopedic Hip Acquisition and Analysis Software requires a 12 seconds with an entrance radiation exposure to the skin of 53 mrem. This software posses no new safety or efficacy concerns.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Scans of the orthopedic hip region take 12 seconds. The EXPERT-XL Orthopedic Hip software results correlate highly (r =0.97) with DPX series, which already fras 510(k) clearance. Also, the average short term precision (CV) in vivo is 3% or under for all sites, which is comparable to that shown on DPX series densitometers. The entrance radiation exposure to the skin of 53 mrem is higher than that for DPX series densitometers but remains low compared to the maximum permissible dose and to conventional radiographs of the region.

DESCRIPTION OF THE DEVICE: 10.1
The Orthopedic Hip Acquisition and Analysis Software is an accessory software option for the EXPERT-XL Bone Densitometer that allows estimation of Bone Mineral Density BMD (in g/cm2) of periprosthetic bone adjacent to an orthopedic hip implant.
SUMMARY OF TECHNICAL CHARACTERISTICS 10.2
Scans of the orthopedic hip region take 12 seconds. The EXPERT-XL Orthopedic Hip software results correlate highly (r =0.97) with DPX series, which already fras 510(k) clearance. Also, the average short term precision (CV) in vivo is 3% or under for all sites, which is comparable to that shown on DPX series densitometers.
