The summary describes a portable X-ray generator and its components, focusing on hardware, safety features, and basic control algorithms for X-ray output. There is no mention of AI, ML, or any features that suggest learning from data or complex pattern recognition for image analysis or generation control beyond basic parameters. The "algorithm of X-ray output for processing and control" likely refers to standard control logic for generating the X-ray beam, not AI/ML.
No
The device is described as a "portable medical diagnostic-purpose X-ray generator," and its intended use is to produce "diagnostic x-ray images." Diagnostic devices are used to identify or detect medical conditions, not to treat them.
Yes
The device is described as a "portable medical diagnostic-purpose X-ray generator" and is intended for "producing diagnostic x-ray images of extremities". This explicitly states its purpose for diagnosis.
No
The device is described as a portable X-ray generator, which is a piece of hardware that produces X-rays. While it mentions using algorithms for processing and control, the core function and description are centered around the physical X-ray generation hardware.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD devices are used to examine specimens taken from the human body. The definition of an IVD involves testing samples like blood, urine, tissue, etc., outside of the body to provide information about a person's health.
- This device is an X-ray generator. It produces radiation that passes through the body to create images. It does not interact with or analyze biological specimens.
The description clearly states that the device is a "portable medical diagnostic-purpose X-ray generator" used for "producing diagnostic x-ray images of extremities." This is a form of in vivo diagnostic imaging, meaning it's performed on a living organism.

Device Description
Mine 2.1, a portable X-ray generator, is radiation medical equipment that can only be used by professional radiologists. It controls and marks X-ray dose within the range of X-ray exposure limited by hardware. Also, it uses the algorithm of X-ray output for processing and control. This portable X-ray generator requires equipment for X-ray imaging in order to generate X-ray images. Small in size, this product is convenient to carry with, and suitable for being moved around. The main body can be compatibly used with a stand. When attached to a stand, it is easy to adjust positioning for medical imaging. MINE ALNU is programmed to be inoperable when the SSD is less than 40cm to the irradiation target.

Dear Mr. Kim:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

9. Discussion of Differences
| SE-# | SE discussion |
|---|---|
| 1, 2 | Both devices are DC-powered by battery while charged with AC-power. |
| Tube potential and mAs for the subject device are similar to those of the | |
| predicate device. The subject device has a fixed tube current of 3mA | |
| whereas the predicate device can vary between 2mA ~ 6mA. Both | |
| exposure power settings are capable of producing diagnostic x-ray images | |
| of extremities for adult and pediatric patients. | |
| 3 | X-ray tube specifications are different but both X-ray tube models are |
| capable of producing diagnostic x-ray images of extremities for adult and | |
| pediatric patients. | |
| 4 | The minimum filtration reduces patient radiation dose by eliminating low |
| energy that would otherwise be absorbed by the patient's skin. | |
| Positive means are determined through linear interpolation to provide that | |
| at least the minimum filtration needed to achieve the above beam quality | |
| requirements is in the useful beam during each exposure, according to the | |
| HVL provisions of 1020.30(m)(1). |
10.Summary of the technological characteristics of the device compared to the predicate device:
The indications for use, mechanical components, performances and safety characteristics of Mine 2.1 portable X-ray series described in this 510(k) are similar to those of the predicate device.
The primary differences are the specifications of X-ray tube, and X-ray generator of the subject device. The performance specifications of the subject device are similar or higher than that of the predicate device such as the X-ray generator and X-ray tube
9
anode heat content (Heating Unit).
These differences do not have any effects on safety and effectiveness compared to the predicate device.
11. Performance Testing/Data
Testing for verification and validation of the device was found acceptable to support the claims of substantial equivalence. Safety and EMC compliance were evaluated according to the IEC Standards. Radiation leakage test and image quality studies have been tested and the results met the acceptance criteria and limitations of the subject device. HDT Co., Ltd certifies conformance to Voluntary Standards covering electrical and mechanical safety. In conclusion, the identified risk of electrical hazards was mitigated and is substantially equivalent to the predicate device in terms of safety and effectiveness.
12.Description of non-clinical tests.
Mine 2.1 diagnostic X-ray system has been tested for electrical safety and electromagnetic compatibility (IEC 60601-1-2, IEC , IEC 60601-2-54, IEC 60601-1-3, IEC 60601-2-28, and IEC 60601-1:2005.) The device also complies with FDA EPRC Performance Standard: 21 CFR 1020.30 and 31. The software validation and verification testing was also performed. The results of nonclinical testing indicate that the Mine 2.1 mobile X-ray system is as safe and effective as the predicate device. Compliance evidences were submitted for the following standards:
- IEC 60601-1: Test Report issued by 3rd party testing lab A
- IEC 60601-1-2: Test Report issued by 3rd party testing lab A
- IEC 60601-1-3: Test Report issued by 3rd party testing lab A
- IEC 60601-2-54: Test Report issued by 3rd party testing lab A
- EPRC Standard: 21 CFR 1020.30 and 31: In-house Test Report A

13.Description of clinical tests.
No clinical data is necessary to evaluate safety or effectiveness for purposes of determining substantial equivalence of the proposed modification. Bench testing was performed to assess the device safety and effectiveness.
14.Conclusion as to Substantial Equivalence
MINE 2.1 are substantially equivalent to the predicate device P Remex KA6 (K212144). These 2 devices are very similar in the intended use, the design principle, the performance and the applicable standards. Some characteristics, for example, their appearance, the user interfaces and the capacity of X-ray generator and X-ray tube are different. However the compliance reports, performance demonstrations and description of non-clinical review result in this submission STED provide demonstration that these differences do not raise any new questions of safety and effectiveness. Therefore, HDT CO., LTD. concludes Mine 2.1 of mobile X-ray system are substantially equivalent with the predicate device Remex KA6 (K212144) of Remedi Co., Ltd.
