Intended Use
The DPX-RX Bone Densitometer provides an estimate of BMD at the lumbar Spine and proximal femur regions. This BMD value can then be compared to a reference population at the sole discretion of the physician. The use of the DPX-RX Bone Densitometer is restricted to prescription use only.
Device Description
The DPX-RX Bone Densitometer provides an estimation of Bone Mineral Density (BMD in g/cm2) of the lumbar spine and the proximal femur.
More Information

No
The summary does not mention AI, ML, or any related concepts, and the device description and performance studies focus on standard bone densitometry measurements and comparisons to predicate devices.

No
The device is used to estimate Bone Mineral Density (BMD) for diagnostic purposes, not to treat or cure a disease or condition.

Yes
The device "provides an estimate of BMD," which is then "compared to a reference population" to assess bone health, indicating its role in identifying or characterizing a condition.

No

The device is described as a "Bone Densitometer," which is a type of hardware device used to measure bone density. The description and performance studies refer to in vitro and in vivo measurements, which are characteristic of a physical device interacting with a patient. There is no mention of the device being solely software.

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 DPX-RX Bone Densitometer measures bone mineral density directly on the patient's body (in vivo) using a non-invasive method. It does not analyze samples taken from the body.
  • Intended Use: The intended use describes the device as providing an estimate of BMD at specific anatomical sites on the patient.

Therefore, the DPX-RX Bone Densitometer falls under the category of a medical device used for diagnostic purposes, but not an in vitro diagnostic device.

Summary of Performance Studies

The BMD estimations in vivo provided by the DPX-RX correlate r>0.98 with the DPX-L. The average BMD values obtained in 50 subjects in vivo were very similar with DPX-L and DPX-RX. The average short-term precision (%CV) in vitro was

(a)
Identification. A bone densitometer is a device intended for medical purposes to measure bone density and mineral content by x-ray or gamma ray transmission measurements through the bone and adjacent tissues. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II.

10.1 DESCRIPTION OF THE DEVICE:

The DPX-RX Bone Densitometer provides an estimation of Bone Mineral Density (BMD in g/cm2) of the lumbar spine and the proximal femur.

SUMMARY OF TECHNICAL CHARACTERISTICS 10.2

The DPX-RX Bone Densitometer performs a 30-second scan, with a total skin exposure dose of 2.5 mrem per measurement. The radiation exposure of 2.5 mrem is comparable to the predicate DPX-L, and is ten times lower than predicate fanbeam densitometers such as the EXPERT.

The BMD estimations in vivo provided by the DPX-RX correlate r>0.98 with the DPX-L. The average BMD values obtained in 50 subjects in vivo were very similar with DPX-L and DPX-RX. The average short-term precision (%CV) in vitro was "United States Federal Law restricts this device to the sale, distribution, and use by or on the order of a physician."
