Intended Use

Edge Air(1417) Digital Flat Panel X-Ray Detector is indicated for digital imaging solution designed for general radiographic system for human anatomy. It is intended to replace film or screen based radiographic system in all general purpose diagnostic procedures. Not to be used for mammography.

Device Story

Edge Air (1417) is a wired/wireless digital solid-state X-ray detector using flat-panel technology. It captures X-ray images and converts them into digital signals via a scintillator coupled to an a-Si TFT sensor. The device integrates with radiographic imaging systems to replace film/screen-based systems. Wireless communication (IEEE 802.11a/g/n/ac) transmits captured images to a separate console running Xmaruview V1 software (K190866) for processing into DICOM-compatible files. Used in clinical settings by healthcare professionals for diagnostic radiography. The output allows clinicians to view and analyze radiographic images, facilitating diagnostic decision-making and patient care. The device is a smaller-sized version of the predicate Edge Air (K172681), sharing identical hardware and firmware.

Clinical Evidence

Clinical evidence consists of a comparative review of sample radiographs by a licensed radiologist. Images from the subject device and predicate were compared across similar patient age groups and anatomical structures. The expert opinion concluded that spatial and soft tissue contrast resolutions are equivalent, with soft tissues on extremity films showing comparable or better clarity. Bench testing (MTF, DQE, NPS) per IEC 62220-1 was also provided to support equivalence.

Technological Characteristics

Flat-panel detector using Amorphous Silicon (a-Si) TFT sensor with Cesium Iodide (CsI:TI) scintillator. Dimensions: 384 x 460 x 15 mm. Connectivity: Wireless IEEE 802.11 a/g/n/ac (2.4/5 GHz).

Dear Mr. Chon:

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.

#### 6. Summary of Performance Testing compared with predicate device

The Edge 44(1417) Digital Flat Panel X-Ray Detector has the same indications for use, material, form factor, performance, and safety characteristics compared to the predicate device, Edge Au.

The non-clinical test and clinical consideration test for the Edge Ait have been performed to demonstrate the substantial equivalency of the subject devices compared to the predicate device, Edge A. The non-clinical test report contains the MTF, DQE and NPS test results of Edge 44"(1417) by using the identical test equipment and same analysis method described by IEC 62220-1.

The comparative result of the MTF and DQE test for Edge ^(1417) detector with respect to the predicate demonstrated that the MTF and DQE of the subject devices performed same with the predicate device, Edge Air. The MTF and DQE represent the ability to visualize object details of a certain size and contrast. The comparable performance of the MTF and DQE for the Edge Air(1417) detector demonstrated that the performed almost same with Edge Air.

To further demonstrate the substantial equivalency of the Edge **(1417), clinical images have been reviewed by a licensed radiologist to render an expert opinion. The test subject (Edge Air(1417)) and the predicate device (Edge Air) have been evaluated and compared by talking sample radiographs of similar age group and anatomical structures in accordance with the test protocol of diagnostic radiography evaluation procedure.

After a broad review of plain radiographic images taken with the Edge Air(1417), the image obtained with the Edge 4"(1417) is similar to the same view obtained from a similar patient with the predicate device, Edge 44. In general, the spatial and soft tissue contrast resolutions for both devices are equivalent. Specially, the soft tissues on extremity films were seen with better clarity.

Based on the non-clinical and clinical consideration test and the outcome of a comparative review by an expert for the Edge All(1417), the sponsor can claim the substantial equivalency between the subject device and the predicate device in terms of diagnostic image quality.

The manufacturing facility is in conformance with the design control procedure requirements and the relevant EPRC standards as specified in 21 CFR 802.30 and the records are available for review.

Note: Clinical images were provided; even though these images are not necessary to establish substantial equivalence based on the modifications to the device, they provide additional evidence in addition to bench testing data to show that the complete system works as intended.

#### 7. Summary for any testing in the submission:

Electrical, mechanical, environmental safety and performance testing according to standard IEC 60601-1:2005 (3rd Edition) + CORR. 1:2006 + CORR. 2:2007 + A1:2012 (Medical electrical equipment Part 1: General requirements for basic safety and essential performance) was performed, and EMC testing were conducted in accordance with standard IEC 60601-1-2:2007.

The Non-clinical consideration & performance test have been conducted according to the following FDA Guidance.

- Performance Standards for Ionizing Radiation Emitting Products, 21 CFR 1020 -
- Diagnostic x-ray systems and their major components, 21 CFR 1020.30 -
- -Radiographic Equipment, 21 CFR 1020.31
