The summary describes a standard digital X-ray detector and its image acquisition and processing capabilities, but there is no mention of AI, ML, or related concepts like deep learning or neural networks in the device description, intended use, or performance studies. The focus is on the hardware and basic digital image processing.
No
The device is an imaging device used for diagnosis, not for treating a condition or disease.
Yes
This device is an X-ray imaging device. It is intended to replace film or screen-based radiographic systems in all general purpose diagnostic procedures and can be used for digitizing and transferring X-ray images for radiological diagnosis.
No
The device description explicitly states it is an "x-ray imaging device" that "utilizes amorphous silicon and a high-performance scintillator" and is a "flat panel based X-ray image acquisition device." These are hardware components, not solely software. While it includes software validation, it is part of a larger hardware system.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use clearly states it's for "digital imaging solution designed for general radiographic system for human anatomy." This describes an in-vivo imaging device, meaning it's used to image structures within the living body.
- Device Description: The description details an "x-ray imaging device" that "can acquire and process X-ray images." This aligns with in-vivo imaging, not testing samples outside the body.
- Input Imaging Modality: The input modality is "X-ray," which is used for in-vivo imaging.
- Anatomical Site: The anatomical site is "human anatomy," further indicating in-vivo use.
In Vitro Diagnostics (IVDs) are medical devices used to examine specimens, such as blood, urine, or tissue, taken from the human body to provide information for diagnosis, monitoring, or screening. This device does not perform such tests on specimens.

Dear Woo Chai Kyoung:
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. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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
