The GR40CW Digital X-ray Imaging System is intended for use in general projection radiographic applications wherever conventional screen-film systems or CR systems may be used. This device is not intended for mammographic applications.
The GR40CW digital X-ray imaging system consists of Detector, Power supply box, Battery pack, Battery charger, Access point, CIB(Control Interface Box), Workstation, Barcode scanner, Main cable and software for image acquisition and image processing and does not include the X-ray generator. This 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 GR40CW digital X-ray imaging system was previously cleared with K180543, and through this premarket notification, we would like to add more configurations in the previously cleared GR40CW as three detectors are newly added, and some software features called as SimGrid, S-Enhance, BSI (Bone Suppression Image), Remote View and manual Stitching are newly added as stated below. SimGrid software option, cleared with K171119. is able to compensate the contrast loss due to scatter radiations, primarily acquisitions without a physical anti-scatter grid. BSI software option suppresses bone anatomy and S-Enhance is renamed from Tube & Line Enhancement (TLE), which was cleared before with the predicate device GM85 at K171119, to enhance visibility of tubes and lines and provide enhanced images separately from original images. In this submission, the scope of S-Enhance is expanded from tubes and lines on chest images to foreign body (e.g. tubes, lines and needles) and urinary stones on chest, abdomen, and L-spine. And Manual Stitching to capture a body part that is larger than the detector's by capturing multiple images and Remote View function to remote access to view the current image on the workstation through a web browser. It was determined that the level of concern for the software contained in the GR40CW digital X-ray imaging system was Moderate in accordance with the FDA guidance for the Content of Premarket Submissions for Software Contained in Medical Device".
Here's a breakdown of the acceptance criteria and study information for the GR40CW device, based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
The document doesn't explicitly list a table of "acceptance criteria" with pass/fail thresholds in the typical sense for product validation. Instead, it focuses on demonstrating substantial equivalence to predicate devices. The performance evaluation is primarily comparative.
However, based on the non-clinical and clinical data descriptions, we can infer the key performance areas evaluated and the general finding of equivalence.
| Performance Metric Area | Acceptance Criteria (Inferred from Substantial Equivalence) | Reported Device Performance |
|---|---|---|
| Non-Clinical Data | Performance equivalent to predicate device (K180543) | No significant difference in non-clinical testing data (MTF and DQE measurements) compared to the predicate device. |
| MTF (Modulation Transfer Function) | Equivalent to predicate device | Met (no significant difference reported) |
| DQE (Detective Quantum Efficiency) | Equivalent to predicate device | Met (no significant difference reported) |
| Clinical Data (S-Enhance) | Image quality equivalent to predicate devices for new detector and S-Enhance (expanded scope) | No significant difference in the average score of image quality evaluation between the proposed device and the predicate device. S-Enhance confirmed to generate clear companion images for foreign bodies and urinary stones. |
2. Sample Size Used for the Test Set and Data Provenance
- Test Set for New Detector and S-Enhance (Clinical Data):
- Sample Size: Not explicitly stated as a number of images or patients. It mentions "Anthropomorphic phantom images were provided"; and "these images were not necessary to establish substantial equivalence... but they provide further evidence...".
- Data Provenance: Not explicitly stated (e.g., country of origin). The study used "Anthropomorphic phantom images," which are specialized phantoms designed to mimic human anatomy for imaging studies. This is a controlled, laboratory-based setup rather than real patient data. It is a prospective study design as the images were "provided" for evaluation.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- Number of Experts: Not explicitly stated. The document mentions "They were evaluated by professional radiologists." The exact number (e.g., 3, 5, 10) is not provided.
- Qualifications: "Professional radiologists." No specific years of experience or subspecialty are listed.
4. Adjudication Method for the Test Set
- Adjudication Method: Not explicitly stated. The text only says "They were evaluated by professional radiologists." This implies individual evaluation, but it doesn't describe a consensus or majority rule method if multiple radiologists were involved, nor does it specify if a single radiologist was the sole evaluator.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size
- MRMC Study: No, a formal MRMC comparative effectiveness study, comparing human readers with AI assistance versus without AI assistance, was not explicitly detailed or performed as part of this submission. The clinical data section focuses on "Anthropomorphic phantom images" evaluated by radiologists to demonstrate equivalence of the device (including the S-Enhance feature) to predicate devices, not on the improvement of human performance using the AI feature.
- Effect Size: Not applicable, as an MRMC study demonstrating human reader improvement with AI assistance was not described.
6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done
- Standalone Performance: The non-clinical data provides standalone performance metrics for the device components like MTF and DQE (measured by IEC 62220-1), which characterize the imaging chain's inherent physical performance.
- For the software features like S-Enhance, the clinical data describes evaluations by radiologists of images generated by the software. While radiologists evaluate the output, the core performance of the S-Enhance algorithm in creating the companion images is assessed based on their ability to "provide clear visibility for foreign bodies such as lines, and needles, and urinary stones." This suggests a form of standalone performance evaluation of the algorithm's output, even if human experts are interpreting that output. The submission aims to show the complete system works as intended and that S-Enhance produces images with desired characteristics.
7. The Type of Ground Truth Used
- Ground Truth Type: For the clinical evaluation regarding the new detector and S-Enhance, the ground truth was expert consensus/opinion (professional radiologists) on the "image quality evaluation" and the "clear visibility for foreign bodies... and urinary stones" in images generated from anthropomorphic phantoms. Phantoms provide a known truth in terms of implanted objects.
8. The Sample Size for the Training Set
- Training Set Sample Size: Not provided or discussed in this document. This submission pertains to modifications to an already cleared device, and the focus is on the performance of the new detectors and expanded software features (S-Enhance). Details about the training data for the S-Enhance or other software algorithms are not included.
9. How the Ground Truth for the Training Set Was Established
- Training Set Ground Truth Establishment: Not provided or discussed, as the training set sample size was not mentioned.

Integration Information
This is a retrofit system consisting of Detectors, Power supply box, Battery charger, Access point, CIB (Control Interface Box), Workstation, Barcode scanner and Main cable. This retrofit system is designed to generate a digital image while using the current analogue X-ray system by upgrading only the part of an analogue cassette film to the digital panel(detector), and does not get involved in controlling X-ray radiation related parameters, which is still controlled by the existing X-ray system.
The GR40CW retrofit system can be applied to the existing analogue X-ray system by two ways (CIB and AED modes). 1) In CIB mode, CIB is only connected to a signal line of a hand switch for passively detecting the signal, as On or Off, coming out from the hand switch to the X-ray Generator Console, to make the digital detector ready to active or inactive to receive Xray radiation. 2) In AED (Automatic Exposure Detection) mode, without CIB, the detector is sensing of radiation exposure. Once it recognizes the exposure, it become active right away to receive X-ray radiation. This whole process is independently operated from the existing

Image /page/5/Figure/3 description: The image shows two integration diagrams, one for CIB mode and one for AED mode, of a GR40CW Retrofit Kit with an existing X-ray system. The CIB mode diagram shows the GR40CW Retrofit Kit consisting of a detector, workstation, and CIB, connected to the existing X-ray system, which includes an X-ray generator console and a hand switch. The AED mode diagram shows the GR40CW Retrofit Kit consisting of a detector and workstation, connected to the existing X-ray system, which includes an X-ray generator console and a hand switch. The diagrams illustrate the flow of signals and the components involved in each mode.
In conclusion, this retrofit kit does not either require a modification / alteration or control in the part of X-ray radiation control of the current X-ray system in anyway.
8. Intended Use
The GR40CW Digital X-ray Imaging System is intended for use in general projection radiographic applications wherever conventional screen-film systems may be used. This device is not intended for mammographic applications.
9. Summary of Technological characteristic of the proposed device compared with the predicate device

510(k) Premarket Notification - Traditional
D. Clinical data
Phantom image evaluations for the new detector and S-Enhance were performed in accordance with FDA guidance for the submission of 510(k)'s for Solid State X-ray Imaging Devices. Anthropomorphic phantom images were provided; these images were not necessary to establish substantial equivalence based on the modifications to the device (note X-ray flat-panel detector similar to the predicate detector) but they provide further evidence in addition to the performance data to show that the complete system works as intended. They were evaluated by professional radiologists and found to be equivalent to the predicate devices. There is no significant difference in the average score considering the standard deviation of image quality evaluation between the proposed device and the predicate device and it is confirmed that S-Enhance is able to generate a companion image which provide clear visibility for foreign bodies such as lines, and needles, and urinary stones in chest, abdomen, and L-spine protocol in addition to the original images. Therefore, these changes do not affect either the safety or the effectiveness, compared to the predicated device.
E. Conclusions
The results of the non-clinical data & clinical data demonstrate that the proposed device is as safe, as effective, and performs as well as the legally marketed devices.
