Intended Use

Ai Ray Dental X-Ray Device is an extraoral diagnostic dental X-ray source to produce X-ray images using intraoral image receptors. It is indicated for use by a dental technician for both adult and pediatric patients.

Device Description

Ai Ray Dental X-Ray Device is a super capacitor-operated, portable dental X-ray source designed for handheld operation. It is designed to produce diagnostic quality X-rays images utilizing either film or digital imaging techniques. The Portable Dental X-ray Device is designed for use in a dental office. It can also be used in other similar environments (orthodontic office, general practitioner's office, hospital ward, etc.) where appropriate safeguards are implemented. The device uses a rechargeable supercapacitor to allow for the use of the Portable Dental X-ray Device where transportation or use of other x-ray devices might be prohibitive due to the other device's size and/or lack of mobility.

2. Sample Size Used for the Test Set and Data Provenance

The document does not provide details on a specific "test set" for performance evaluation in the context of clinical data. Instead, it refers to Non-Clinical Performance Testing to verify substantial equivalence, focusing on compliance with established standards.

  • Sample Size for Test Set: Not applicable in the context of clinical data for this submission. Performance was validated through compliance with standards.
  • Data Provenance: Not applicable for clinical data. The device itself is manufactured by Guilin Woodpecker Medical Instrument Co., Ltd. in China.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of those Experts

As no clinical data or test set requiring expert ground truth for comparison was used for this 510(k) submission, this information is not applicable. The device's performance was evaluated against technical and safety standards.

4. Adjudication Method for the Test Set

Not applicable, as no clinical test set requiring adjudication of ground truth was described.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done

No. The document explicitly states: "No clinical data was required to demonstrate substantial equivalence." Therefore, no MRMC study comparing human readers with and without AI assistance was performed or reported.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) was Done

No, this device is a physical X-ray device, not an AI algorithm. Its performance is related to its ability to generate X-ray images, not to interpret them or to function as a standalone AI system.

7. The Type of Ground Truth Used

The "ground truth" for the device's acceptance is its compliance with technical and safety standards (e.g., IEC 60601 series, FDA regulations 21 CFR 1020.30, 21 CFR 1020.31) and its substantial equivalence to a legally marketed predicate device. This is primarily assessed through non-clinical performance testing to verify the device's technical specifications and safety parameters.

8. The Sample Size for the Training Set

Not applicable. As this device is a physical X-ray generator, it does not involve a "training set" in the context of machine learning or AI algorithms.

9. How the Ground Truth for the Training Set was Established

Not applicable, as there is no training set for this device.

Device Description:

Ai Ray Dental X-Ray Device is a super capacitor-operated, portable dental X-ray source designed for handheld operation. It is designed to produce diagnostic quality X-rays images utilizing either film or digital imaging techniques. The Portable Dental X-ray Device is designed for use in a dental office. It can also be used in other similar environments (orthodontic office, general practitioner's office, hospital ward, etc.) where appropriate safeguards are implemented. The device uses a rechargeable supercapacitor to allow for the use of the Portable Dental X-ray Device where transportation or use of other x-ray devices might be prohibitive due to the other device's size and/or lack of mobility.

The proposed Ai Ray Dental X-Ray Device is similar in design to the predicate EzRay Air Portable, VEX-P300 (K200182). The proposed Ai Ray Device and the predicates is a portable dental X-ray system intended for use by a trained and qualified dentist or dental technician for both adult and pediatric subjects for producing diagnostic dental radiographs for treatment of diseases of the teeth, jaw, and other oral structures using intra-oral image receptors.

The differences between the proposed Ai Ray Dental X-Ray Device and the predicate EzRay Air Portable, VEX-P300 (K200182) are as follows:

  1. The opening key is positioned differently, EzRay Air Portable at the bottom and Ai Ray at the top.

  2. The structural shapes of the two devices are different.

Principles of Operation

The equipment acquires images by emitting X-rays continuously on a human tooth. X-rays are emitted when high voltage is supplied to the X-ray tube assembly, which frees electrons from the cathode. They hit the anode to produce X-rays.
