Intended Use

1717WCC and 1717WGC Digital Flat Panel X-Ray Detectors are indicated for digital imaging solution designed for general radiographic system for human anatomy. It is intended to replace film or screen based radiographic systems in all general purpose diagnostic procedures. Not to be used for mammography.

Device Story

1717WCC/1717WGC are wired/wireless digital flat-panel X-ray detectors; utilize scintillator coupled to a-Si TFT sensor to capture X-ray signals; convert X-rays to digital RAW image files. Used in clinical settings (upright stands, tables, universal stands) by radiographers/technicians. Integrated with radiographic imaging systems; RAW files transmitted via wireless LAN (IEEE 802.11a/g/n/ac) or wired connection to console software (e.g., Xmaru View V1/PACS) for conversion to DICOM format. Healthcare providers view DICOM images for diagnostic analysis; output supports clinical decision-making by providing high-resolution radiographic images for general anatomy diagnosis. Benefits include improved operability, high-speed processing, and portability compared to film-based systems.

Clinical Evidence

Clinical evaluation involved a comparative review of sample radiographs taken with subject and predicate devices. A licensed US radiologist reviewed images of similar age groups and anatomical structures. Results indicated subject devices provided superior spatial and soft tissue contrast resolution, particularly in extremity films, with no difficulty in evaluating anatomic structures for diagnostic conclusions.

# 6. Summary of Performance Testing

1717WCC and 1717WGC Digital Flat Panel X-Ray Detector have the same indications for use, material, form factor, performance, and safety characteristics compared to the predicate devices, 1717SCN and 1717SGN, respectively.

The non-clinical test and clinical consideration test for each subject device were performed to demonstrate the substantial equivalency of the subject devices compared to each respective predicate device. The nonclinical test report contains the MTF, DQE and NPS test results of 1717WCC and 1717WGC 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 1717WCC detector with respect to each respective predicate demonstrated that the MTF and DQE of the both subject devices performed better

{8}------------------------------------------------

#### 510(k) Submission – 1717WCC / 1717WGC

compared with each respective predicate device. The MTF and DQE represents the ability to visualize object details of a certain size and contrast. 1717WCC has higher MTF and DQE performance at high spartial frequencies, especially from 2 1p/mm. The comparison of the MTF and DQE for 1717WGC detector demonstrated that the performed almost same with 1717SGN.

This information will be included as a part of proposed labeling documentation for the end user.

To further demonstrate the substantial equivalency of two devices, clinical images are taken from both subject devices and reviewed by a licensed US radiologist to render an expert opinion. Both the test subject (1717WCC and 1717WGC) and the predicate devices (1717WGC and 1717SGN) have been evaluated and

{9}------------------------------------------------

compared by taking sample radiographs of similar age groups 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 1717WCC and the 1717WGC, the images obtained with the 1717WCC and 1717WGC are superior to the same view obtained from a similar patient with the predicate devices, 1717WGC and 1717SGN. In general, both the spatial and soft tissue contrast resolution are superior using the 1717WGC. Specifically, the soft tissues on extremity films were seen with better clarity. There is little difficulty in evaluating a wide range of anatomic structures necessary to provide a correct conclusion.

Based on the non-clinical and clinical consideration test and the outcome of a comparative review by an expert for both devices, the sponsor can claim the substantial equivalency between the subject devices and their predicate devices 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.
