No
The description mentions an "advanced noise reduction algorithm" and "image processing algorithm" but does not explicitly state or imply the use of AI or ML techniques. The focus is on improving image quality through algorithmic processing, which is common in medical imaging without necessarily involving AI/ML.
No.
The device is used to generate radiographic images for diagnostic purposes, not to treat or cure a disease.
Yes
Explanation: The device creates radiographic images of human anatomy, which are then used by qualified doctors or technicians for reading and interpretation. This process is integral to diagnosis.
No
The device description clearly states it is a "Digital X-ray imaging system" which includes hardware components like an X-ray transmitter, detector, and signal process device, in addition to the software (S-Station and Image Post-processing Engine). While the submission focuses on the software upgrade, the overall device is a hardware system with integrated software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The GC85A Digital X-ray Imaging System is used to generate radiographic images of human anatomy by transmitting X-rays through the body. It does not perform tests on samples taken from the body.
- Intended Use: The intended use is for generating radiographic images for diagnostic purposes, not for analyzing biological samples.
- Device Description: The description focuses on the process of capturing and processing X-ray images, not on analyzing biological specimens.
Therefore, the GC85A Digital X-ray Imaging System falls under the category of medical imaging devices, not In Vitro Diagnostics.

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.

Description of the test set, sample size, data source, and annotation protocol
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.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
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.
