No
The document describes image processing algorithms (WDV) but does not mention AI, ML, or deep learning, nor does it provide details about training or test sets typically associated with AI/ML models.
No
The device is described as diagnostic software for X-ray images, primarily for viewing, analyzing, transferring, and printing medical images, and performance tests focus on image enhancement and compatibility for diagnostic purposes rather than directly treating a condition.
Yes
The "Intended Use / Indications for Use" states that the software "analyzes" medical images, and the "Device Description" explicitly calls it "a diagnostic software."
No
The device description explicitly states it is "diagnostic software for final postprocessed X-ray images of body parts of actual patients acquired through the integration of digital X-ray detectors (DXD+ASHK100G... compatible LG DXD series) and X-ray generators." It also mentions compatibility tests with LG DXDs and generators, indicating a direct interaction and reliance on specific hardware components for image acquisition and processing. While the device is software, it is not software-only as it is intrinsically linked to and functions in conjunction with specific hardware.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens from the human body. The intended use and device description clearly state that this software processes and analyzes medical images of actual patients acquired through X-ray. It does not involve the analysis of biological samples like blood, urine, or tissue.
- The focus is on image processing and viewing. The software's functions revolve around manipulating and displaying medical images for diagnostic purposes, which falls under the category of medical imaging software, not IVD.
Therefore, while this is a medical device used for diagnosis, it does not fit the definition of an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance for WDV (Wide Dynamic View) and Compatibility with Generator Test. The WDV algorithm enhances the performance of the proposed medical device by normalizing tissue through the creation of a regional map based on image location and distribution characteristics, leading to more natural and consistent images. Optimization minimized the increase in image processing time despite high operation quantity. Compatibility tests confirm the proposed device can interface and control the Console workstation and DXDs in real-time without functional bugs, and safety trials ensure values cannot be set beyond limitations.

The proposed device is an updated version of the predicate device, with improvements and changes made to the operations software, image processing algorithm, and measurement tools. More specifically, as shown in the above comparison table, the following items of the proposed device are different from the predicate device: Software version, Processor,
Operation software, Image processing algorithm, and Advanced measurement tools. Software version, Processor and operation software have been updated from the predicate device, and the software has been validated accordingly. In terms of image processing algorithm, the proposed device has undergone a performance testing to assess the new WDV algorithm.
The newly added advanced measurement tools have been validated and verified by the software validation.
Based on those reviews, it has been determined that these changes do not have any negative impact on the safe and effective use of the product.
8. Non-Clinical Test Summary [21 CFR 807.92(b)(1)]
The following data were provided in support of the substantial equivalence determination:
1) Software Validation
The ASHK100G belongs to a Basic Documentation Level. The software was designed and
developed according to a software development process and was verified and validated.
Software information is provided in accordance with FDA guidance:
- · The content of premarket submissions for Device Software Functions (June 14, 2023)
2) Cybersecurity
Cybersecurity documents are provided in accordance with the below FDA guidance:
- · Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions (September 27, 2023)
- Postmarket Management of Cybersecurity in Medical Devices (December 28, 2016)
- Performance Test
- Performance for WDV (Wide Dynamic View) ●

Image /page/9/Picture/0 description: The image shows the LG Electronics logo. The logo consists of a red circle with a stylized "L" and "G" inside, followed by the text "LG Electronics" in gray. The logo is simple and modern, and it is easily recognizable.
● Compatibility with LG DXD
The performance test report for the addition of the Wide Dynamic View (WDV) algorithm, as well as the compatibility tests with LG DXD (Digital X-ray Detector) and generators, have been submitted as part of the nonclinical tests.
The performance test results indicate that the WDV algorithm enhances the performance of the proposed medical device by normalizing tissue through the creation of a regional map based on image location and distribution characteristics. This leads to more natural and consistent images compared to those that rely solely on residual and image brightness signal composition. Despite the inclusion of algorithms with a high operation quantity, the optimization process has minimized the increase in image processing time.
In conclusion, the addition of the WDV feature has not had any negative impact on the performance and safety of the proposed device.
The compatibility tests with LG DXDs and generators also confirm that the proposed device can interface and control the Console workstation and DXDs in real-time without any functional bugs. Additionally, safety trials have been conducted to ensure that values cannot be set beyond the limitations.
9. Clinical Test Summarv [21 CFR 807.92(b)(2)]
No clinical studies were considered necessary and performed.
The main improvement in the proposed device, as compared to the predicate, is the addition of the WDV algorithm to the existing imaging processing. It is important to note that this update does not require clinical testing. Instead, the performance test for the WDV algorithm includes clinical opinions on the images processed with WDV. Therefore, a separate clinical study is not applicable in this case.
10. Conclusion [21 CFR 807.92(b)(3)]
Based on the information provided in this premarket notification and in accordance with the Federal Food, Drug, and Cosmetic Act, 21 CFR Part 807, LG Electronics Inc. has determined that there are no significant differences between the proposed device and the predicate device that would negatively impact its use. The proposed device has been shown to be as safe and effective as the predicate version previously cleared in K212137. It shares the same intended

use and similar technological characteristics, with any differences supported by performance testing. Therefore, the technological variances between the proposed device and its predicate device do not raise any new concerns regarding safety or effectiveness, and the proposed device can be considered substantially equivalent to the predicate device.
