AI/ML (Artificial Intelligence / Machine Learning)

No
The summary describes a portable X-ray unit and its intended use, safety standards, and software validation. There is no mention of AI or ML in the device description, intended use, or performance studies. The "Mentions AI, DNN, or ML" section explicitly states "Not Found".

Therapeutic

No
This device is for diagnostic purposes (generating X-rays for diagnosis, taking diagnostic radiographic exposures) and does not provide an active treatment or therapy.

Diagnostic

Yes
The document states that the device is intended for "taking diagnostic radiographic exposures" and "to assist the diagnosis of bones and tissues". The "Intended Use / Indications for Use" section also clearly indicates its purpose is for "diagnosis".

SaMD (Software as a Medical Device)

No

The device is described as a "Portable X-ray unit" and mentions components like a "Battery Type Portable X-ray Unit" and a "Rechargeable Li-ion polymer battery pack," indicating it is a hardware device that generates X-rays. While it includes software, it is not solely software.

IVD (In Vitro Diagnostic)

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 POSKOM Portable X-ray unit generates X-rays to create images of the internal structures of the body (bones and tissues). This is an in vivo diagnostic method, meaning it is performed on the living body.
Intended Use: The intended use clearly states it's for taking diagnostic radiographic exposures of body parts for diagnosis. This involves imaging the patient directly, not analyzing samples from the patient.

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

The table also provides rationale for a little difference in support of substantial equivalence to the predicate devices.

Justification to Support Substantial Equivalence

AirRay is hardly different from the TR90BH except for Collimator and X-ray Tube. But the above differences are inherent characteristics of device. The most important tube current and tube voltage range are similar to predicate device.

And Size, Weight, Energy source, Exposure times, Performance standard, Electrical safety are also similar to predicate devices, but they are not items that significantly affect performance, and their intended use is equivalent.

The proposed device, AirRay has been tested about electrical safety, EMC and software has been validated.

8. Non-Clinical Test summary

The AirRay complies with voluntary standards for electromagnetic compatibility.

The following data were provided in support of the substantial equivalence determination:

1) Electrical Safety, Electromagnetic Compatibility and Performance:

The AirRay complies with the electrical safety and electromagnetic compatibility requirements established by the standards.

IEC 60601-1:2005/AM1:2012 Medical electrical equipment - Part 1: General requirement for basic safety and essential performance
IEC 60601-1-2:2014 Medical electrical equipment - Part1-2: General requirements Section1.2 Collateral standard: Electromagnetic compatibility
IEC 60601-1-3:2008 Medical electrical equipment Part 1-3: General requirements for basic safety and essential performance - Collateral standard: Radiation protection in diagnostic X-Ray equipment

13

. IEC 60601-2-54:2009/AM2:2018 Medical electrical equipment Part 2-54: Particular requirements for the basic safety and essential performance of X-Ray equipment for radiography and radioscopy

2) Software Validation

The AirRay contain MODERATE level of concern software. The software was designed and

developed according to a software development process and was verified and validated.

Software information is provided in accordance with FDA guidance:

"The content of premarket submissions for software contained in medical devices, on May 11, 2005"
IEC 62304:2006 (First Edition) Medical device software: Software life-cycle processes

Rechargeable Li-ion polymer battery pack has been tested and is in conformity with the standard IEC 62133. And we performed the battery performance test about battery charging time. discharge time and usage count, Battery rated load, overcurrent protection and recovery.

Furthermore, the following Specific Guidance Document was utilized in the device development to ensure the safety of this device for both the operators and patients:

"Radiation Safety Consideration for X-ray Equipment Designed for Hand-Held Use"

The device also conforms to the following:

21 CFR 1020 Subchapter J: Performance Standards for Ionizing Radiation Emitting Products

21 CFR 1020.30: Diagnostic x-ray system and their major components

21 CFR 1020.31: Radiographic Equipment

9. Conclusion [21 CFR 807.92(b)(3)]

The AirRay has similar intended use and technical characteristics to the predicate device. Based on this information, we conclude that the differences between the proposed device and predicate device do not introduce a new intended use and do not raise new issues of safety and effectiveness.
