## Intended Use

The GC85A Digital X-ray Imaging System is intended for use in generating radiographic images of human anatomy by a qualified/trained doctor or technician. This device is not intended for mammographic applications.

## Device Story

The GC85A is a stationary digital X-ray imaging system used in clinical settings by physicians or technicians. It captures X-ray projections through a patient's body, which are converted into electrical signals by a detector. These signals undergo amplification and digital conversion before being processed by the S-Station software. The system features an upgraded Image Post-processing Engine utilizing an advanced noise reduction algorithm to optimize image quality based on noise distribution and structural information. This allows for a 50% radiation dose reduction for routine PA chest radiography compared to the predicate device. Processed images are saved in DICOM format and transmitted to a PACS server for clinical review. By maintaining diagnostic image quality at lower radiation levels, the device aims to reduce patient radiation exposure during chest imaging.

## Clinical Evidence

Clinical evaluation included 78 in-vivo chest PA image datasets (BMI 15-33) evaluated by three radiologists. Seven anatomical landmarks were assessed, including 18 cases of lung lesions (consolidations, nodules, interstitial markings). Results demonstrated that images acquired at 50% radiation dose reduction using the new engine were substantially equivalent to the predicate device in diagnostic confidence. Phantom studies using the BRH method and SNR/CNR measurements further supported image quality equivalence.

## Technological Characteristics

Stationary digital X-ray system. Hardware is identical to predicate K160997. Features an upgraded software-based Image Post-processing Engine with advanced noise reduction. Connectivity via DICOM to PACS. Complies with ES 60601-1, IEC 60601-1-2, IEC 60601-1-3, IEC 60601-2-28, IEC 60601-2-54, ISO 14971, 21 CFR 1020.30, and 21 CFR 1020.31.

## Regulatory Identification

A stationary x-ray system is a permanently installed diagnostic system intended to generate and control x-rays for examination of various anatomical regions. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

## Special Controls

*Classification.* Class II (special controls). A radiographic contrast tray or radiology diagnostic kit intended for use with a stationary x-ray system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

#### 7. Device Description

The GC85A digital X-ray imaging system is used to capture images by transmitting X-ray to a patient's body. The X-ray passing through a patient's body is sent to the detector and then converted into electrical signals. These signals go through the process of amplification and digital data conversion in the signal process device before being sent to the S-Station (Operation Software) and saved in DICOM file, a standard for medical imaging. The captured images are sent to the Picture Archiving & Communication System (PACS) server, and can be used for reading images.

The Image Post-processing Engine is exclusively installed in S-station, which is a Samsung Digital X-ray Operation Software for Samsung Digital X-ray System. It has an image processing algorithm to improve an acquired image and previously cleared with K160997.

The proposed Image Post-processing Engine is upgraded with employing an advanced noise reduction algorithm to improve image quality. The proposed Engine is shown of a post-processed image as substantially equivalent as the image by the predicate Image Post-processing Engine at a certain low dose level.

This submission is intended to get 510(k) clearance for GC85A with the proposed engine by which the substantially equivalent PA radiograph for average adult chest can be taken using the 50% dose reduction for marketing purpose.

This claim is based on a limited study of an anthropomorphic phantom that simulates the x-ray properties of an average size adult, and on a small clinical study at one facility. Only routine PA chest radiography was studied, and results for larger-size adults (body mass index) greater than 30 was not studied to statistical significance. The new GC85A also was not studied with pediatric patients. The clinical site is responsible for determining whether the particular radiographic imaging needs are not impacted by such x-ray dose reduction.

#### 8. Intended Use

The GC85A Digital X-ray Imaging System is intended for use in generating radiographic images of human anatomy by a qualified/trained doctor or technician. This device is not intended for mammographic applications.

#### 9. Summary of Technological characteristic of the proposed device compared with the predicate device

The proposed device, GC85A has the same hardware characteristics as the predicate device (K160997) and includes an upgraded Image Post-processing engine. It does not have significant changes in materials, energy source or technological characteristics compared to the predicate device.

#### 10. Safety, EMC and Performance Data

Electrical, mechanical, environmental safety and performance testing according to standard ES 60601-1,IEC 60601-1-2, IEC 60601-1-3, IEC 60601-2-28, IEC 60601-2-54, ISO14971, 21CFR1020.30 and 21CFR1020.31 were performed, and EMC testing was conducted in accordance with standard IEC 60601-1-2. Wireless function was tested and verified followed by guidance, Radio frequency Wireless Technology in Medical Devices. All test results were satisfying the standards.

#### 11. Non-clinical data

Non-clinical testing data was provided in conformance to the FDA "Guidance for the Submission of 510(k)'s for Solid-State X-ray Imaging Devices", which includes MTF and DQE measurements as tested by IEC 62220-1.

The proposed Image Post-processing Engine was evaluated with a semi-anatomical chest phantom at a various radiation dose. SNR and CNR were measured to determine image quality with the images taken using the proposed engine or the predicated engine. Overall images using the proposed engine make it easy to distinguish between background and the object and is clearer than images using the predicated engine. The

qualitative side including usefulness was validated by a radiographer using clinical images which was proved in 'Clinical data' section.

#### 12. Clinical data

Phantom image evaluations were performed in accordance with FDA guidance for the submission of 510(k)'s for Solid State X-ray Imaging Devices. They were evaluated by professional radiologists and found to be equivalent to the predicate device.

The proposed engine was validated with anthropomorphic chest phantom images and clinical images by three professional radiologists. Anthropomorphic chest phantom images were scored by Bureau of Radiological Health (BRH) method and inter-observer agreement was calculated. Clinical image evaluations were performed to support phantom study results under the patient informed consent. Total 78 in-vivo data set of chest PA images were evaluated by three experienced radiologists, covering subject's BMI from 15 to 33. Seven anatomical landmarks were evaluated for image quality assessment by three readers, including 18 cases of featured lung lesions of chest PA images, consolidations, nodules and interstitial markings. The images using the proposed engine taken at 50% reduction in radiation dose are substantially equivalent to those using the predicated engine without sacrificing diagnostic confidence.

#### 13. Conclusions

The non-clinical and clinical data demonstrate that the proposed device is as safe, as effective, and performs as well as the legally marketed device.
