### Dear Mr. Wu:

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.

### 5. Description of the Device [21 CFR 807.92(a)(4)]

Venu1748V and DRX-LC digital flat panel detector (Hereinafter referred to as Venu1748V and DRX-LC) are digital large-sized X-ray flat panel detector (FPD) with wireless function based on amorphous silicon (a-Si) thin film transistor (TFT) technology.

Two models Venu1748V and DRX-LC are totally same except for the model name, trade mark, artwork of the protection film. They using cesium iodide (CsI) scintillator, and employ a 3064×8696 active pixel matrix with a pixel size of 139 u m, providing high-quality radiographic images.

Supporting high-speed wireless communication, the equipment can be powered by internal rechargeable battery packs or/and external power charger, making it more flexible and easy to integrate and operate.

iRay SDK(include iDetector) is intend to supply API interface for DR system manufacturers. DR system manufacturer control the detector by SDK interface. SDK is not intended to be used directly by other users beside DR system manufacturers.

iDetector is a tool software based on iRay FPD(Flat Panel Detector) and SDK(Software Development Kit). It can be used for detector configuration, image acquisition, and calibration. So that users can evaluate the performance of iRay detectors at the first time. Also, iDetector can be used as a demonstration program to learn the process controlling and functionality of iRay Detectors and do assessment at user application developing time. This software is moderate level of concern. iDetector does not support image processing after collection.
