The device is a diagnostic X-ray system, which is intended to be used by trained dentists and dental technicians as an extra-oral X-ray source for producing diagnostic X-ray images using intra-oral image receptors. Its use is intended for both adults and pediatric subjects.
The portable x-ray system (Models: MINIX-V, MINIX-S) is an x-ray generating device which is mainly designed for dental examination (teeth and jaw). Operating principle is that the high voltage electricity is getting into x-ray tube and generates x-ray source. This x-ray source comes out from the emitting cone and penetrates teeth and jaw, and makes x-ray images through image receptors (chemical film or digital sensor). Once the power is supplied from the rechargeable lithium-ion polymer battery pack, the inverter generates high frequency and high voltage. Boosted and rectified DC high voltage (MINIX-V: 70kV, MINIX-S: 60kV) is loaded onto the x-ray tube, and the tube generates x-ray. Micro control unit (MCU) and other control parts function to display data on LCD and control the system by the input information from user interface. When operator controlled (fixed amount of) x-ray is exposed to patient's teeth and jaw, clinician can examine the parts with processed images from intra-oral image receptors (analog film, digital phosphor plate or digital sensor). The Portable X-ray System (Models: MINIX-V, MINIX-S) is composed of an x-ray generating part with an x-ray tube, a device controller (Control PCB), a power controller (Power PCB), an user interface (LCD window), a beam limiting part (x-ray emitting cone), a backscatter shield, and a remote control switch (hand-switch). The Portable X-ray System (Models: MINIX-V, MINIX-S) is a diagnostic x-ray system, which is intended to be used by trained dentists or dental technicians. Its use is intended for both adult and pediatric subjects. This device includes a high frequency inverter that changes direct current to alternating current, x-ray tube, electrical protective devices, and other elements. The system with high frequency x-ray provides sharp and clear images, and the total lead protection seal protects patients and dentists from leakage or scattered radiation from the device.
The provided documentation does not contain information about acceptance criteria or a study proving the device meets them in the context of an AI/ML system. The device described, "Portable X-ray System (Models: MINIX-V, MINIX-S)," is an X-ray generating device for dental examinations. The submission focuses on demonstrating substantial equivalence to predicate devices based on safety, electrical, mechanical, and X-ray performance standards, rather than evaluating the performance of an AI/ML algorithm.
Therefore, I cannot provide the requested information regarding acceptance criteria, device performance, sample sizes, data provenance, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth types, or training set details, as these are relevant to AI/ML device evaluations which are not described in this document.
The document states: "Clinical images were provided however they were not necessary in order to establish substantial equivalence with the predicate devices," further indicating that image analysis performance (which would typically involve AI/ML) was not the focus of this submission for substantial equivalence.

Dear Mr. Park:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

11. Conclusion
In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807 and based on the information provided above comparison table, the Portable X-ray System (Models: MINIX-V, MINIX-S) has little difference with its size and user interface as the information in the table. But the system is substantially equivalent to the predicate devices with its design, mechanical and electrical performance as described.
Performance evaluation (test) reports and device inspection report confirmed that the Portable X-ray System (Model: MINIX-V, MINIX-S) is suitable for its intended use and user instruction of the device.
§ 872.1800 Extraoral source x-ray system.
(a)
Identification. An extraoral source x-ray system is an AC-powered device that produces x-rays and is intended for dental radiographic examination and diagnosis of diseases of the teeth, jaw, and oral structures. The x-ray source (a tube) is located outside the mouth. This generic type of device may include patient and equipment supports and component parts.(b)
Classification. Class II.
