Device Description

GC70, GU60&GU60A-65, GF50, GF50A, GR40CW, GM85 and GC85A are 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 on the S-station, which is the Operation Software (OS) of Samsung Digital Diagnostic X-ray System, and save in DICOM file, a standard for medical imaging. The captured images are tuned up by an Image Post-processing Engine (IPE) which is exclusively installed in S-station, SAMSUNG digital X-ray operation software, and sent to the Picture Archiving & Communication System (PACS) sever for reading images.

The IPE operates, from the input image, the roles of a region-of-interest extraction, tonescale mapping, noise reduction and texture restoration. The IPE employing an advanced noise reduction algorithm (hereinafter "new IPE") is shown that the image quality of PA radiograph for average adult chest, exposed at the condition of 50% lower dose at Entrance Skin Exposure (ESE) in comparison with the condition of the conventional noise reduction algorithm (hereinafter "old IPE"), is substantially equivalent.

AI/ML Overview

The provided text describes the acceptance criteria and a study proving the device meets those criteria, specifically concerning dose reduction capabilities of the Image Post-processing Engine (IPE) with an advanced noise reduction algorithm in Samsung Digital X-ray Systems (GC70, GU60A, GU60A-65, GF50, GF50A, GR40CW, GM85, and GC85A).

Here is the requested information:

Acceptance Criteria and Device Performance

1. Table of Acceptance Criteria and Reported Device Performance

The core acceptance criterion is the ability of the new IPE to reduce X-ray dose while maintaining image quality comparable to the old IPE for diagnostic confidence. The specific dose reduction percentages are the performance metrics.

Acceptance CriterionReported Device Performance
Dose Reduction for Adult Abdominal RadiographsUp to 47.5% dose reduction for abdominal radiographs of adult, compared to the old IPE while achieving similar image quality.
Dose Reduction for Pediatric AbdomenUp to 45% dose reduction for pediatric abdomen, compared to the old IPE while achieving similar image quality.
Dose Reduction for Pediatric Chest15.5% dose reduction for pediatric chest, compared to the old IPE while achieving similar image quality.
Dose Reduction for Pediatric SkullUp to 27% dose reduction for pediatric skull, compared to the old IPE while achieving similar image quality.

2. Sample Size Used for the Test Set and Data Provenance

  • Adult Abdominal Radiograph Test Set:

    • Anatomical phantom images: Number of images not specified, but taken at "various exposure condition." The study states, "the new IPE with an advanced noise reduction algorithm retained the quality of images captured at 47.5% reduced exposure in comparison with the old IPE."
    • Clinical images: Number of images not specified, but used to "confirm that it was possible to reduce the dose in clinical images as well."
    • Provenance: Not explicitly stated, but the submission is from Samsung Electronics Co., LTD. Republic of Korea. The clinical testing was conducted at "one medical site."
    • Retrospective or Prospective: Not specified.
  • Pediatric Population Test Set (Chest, Abdomen, Skull):

    • Number of images: "Series of dose-simulated images" for each body part.
    • Number of patients: Not specified explicitly, but mentioned as "each patient."
    • Provenance: Not explicitly stated, but the submission is from Samsung Electronics Co., LTD. Republic of Korea. The clinical testing was conducted at "one medical site."
    • Retrospective or Prospective: Not specified.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

  • Adult Abdominal Radiograph Test Set:

    • Anatomical phantom images were reviewed by three professional radiologists.
    • Clinical images were reviewed by two professional radiologists.
    • Qualifications: "Professional radiologists" (no further details on experience given).
  • Pediatric Population Test Set:

    • Three experienced pediatric radiologists.
    • Qualifications: "Experienced pediatric radiologists" (no further details on experience given).

4. Adjudication Method for the Test Set

The adjudication method is not explicitly detailed. However, for both adult and pediatric studies, images were "scored by the 5-point grading scale" for assessment of image quality. This implies individual scoring, and for the pediatric study, "Three experienced pediatric radiologists assessed the series of dose-simulated images to decide the optimal dose for each patient." The decision for the "optimal dose" for pediatric cases suggests a consensus or agreement among these experts, but the exact method (e.g., majority vote, discussion to reach consensus) is not specified.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance

No MRMC comparative effectiveness study was done to evaluate human readers' improvement with AI vs. without AI assistance. The study focused on the device's standalone performance in enabling dose reduction while maintaining image quality as assessed by human readers. The new IPE is a component within the imaging system, not an AI assistance tool for human readers.

6. If a Standalone (i.e., Algorithm Only Without Human-in-the-Loop Performance) Was Done

Yes, the studies evaluated the standalone performance of the new IPE algorithm in terms of enabling dose reduction while maintaining image quality. The performance was assessed by comparing images processed by the new IPE at reduced doses against images from the old IPE or a reference, with human experts providing the assessment of image quality and diagnostic appropriateness.

7. The Type of Ground Truth Used

The ground truth for both adult and pediatric studies was expert consensus/assessment of image quality and diagnostic appropriateness.

  • For adult abdominal radiographs: Expert radiologists scored images based on a 5-point grading scale, considering anatomical regions, physical parameters, sharpness, and visualization.
  • For pediatric populations: Experienced pediatric radiologists assessed dose-simulated images to determine the "optimal dose" at which image quality remained appropriate for diagnosis.

Additionally, phantom studies (TOR CDR radiography phantom and anthropomorphic phantom) were used to quantitatively assess image quality metrics like Contrast to Noise Ratio (CNR), Detail Compacted Contrast (DCC), and Modulation Transfer Functions (MTF).

8. The Sample Size for the Training Set

The document does not provide information about the training set size for the Image Post-processing Engine (IPE) algorithm. It focuses on the validation of the algorithm's dose reduction capabilities.

9. How the Ground Truth for the Training Set Was Established

The document does not provide information on how the ground truth for the training set was established for the IPE algorithm.

7. Device Description

GC70, GU60&GU60A-65, GF50, GF50A, GR40CW, GM85 and GC85A are 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 on the S-station, which is the Operation Software (OS) of Samsung Digital Diagnostic X-ray System, and save in DICOM file, a standard for medical imaging. The captured images are tuned up by an Image Post-processing Engine (IPE) which is exclusively installed in S-station, SAMSUNG digital X-ray operation software, and sent to the Picture Archiving & Communication System (PACS) sever for reading images.

The IPE operates, from the input image, the roles of a region-of-interest extraction, tonescale mapping, noise reduction and texture restoration. The IPE employing an advanced noise reduction algorithm (hereinafter "new IPE") is shown that the image quality of PA radiograph for average adult chest, exposed at the condition of 50% lower dose at Entrance Skin Exposure (ESE) in comparison with the condition of the conventional noise reduction algorithm (hereinafter "old IPE"), is substantially equivalent. It was cleared with K172229 that using the new IPE is able to reduce dose of 50% for chest PA of average adult in the proposed device, GC85A. The scope of the claim, 50% dose reduction by using the new IPE, was expanded at K180543, from GC85A to GC70, GU60&GU60A-65, GF50, GF50A, GR40CW and GM85. In K180543, it was evaluated that the IPE had no relation with imaging chain and the images acquired by a various imaging chain were substantially equivalent to GC85A (K172229).

Image /page/11/Picture/1 description: The image shows the Samsung logo. The logo is in blue and features the word "SAMSUNG" in bold, white letters. The word is slightly tilted to the right and is enclosed in an elliptical shape.

510(k) Premarket Notification - Traditional

This submission is purposed to get 510(k) clearance for expanding the scope of the dose reduction claims, the chest PA of average adult to abdominal radiograph of adult, cleared with K172229 and K180543, and chest, abdomen and skull of pediatric populations.

The principles of operation and technological characteristics of the proposed devices and the predicate devices are the same. The proposed device is identical to the predicate devices since there are the same devices including the new IPE; however, Samsung would like to expand dose reduction claims to the adult's abdominal radiograph, and the chest, abdomen and skull of pediatric populations for marketing purposes.

The non-clinical and clinical image evaluations show that the proposed devices with the new IPE employing and advanced noise reduction algorithm are able to reduce x-ray dose up to 47.5% for abdominal radiographs of average adult and up to 45% for pediatric abdomen, 15.5% for pediatric chest, and up to 27% for pediatric skull exams, compared with radiation doses needed to obtain similar image quality using the old IPE on the same x-ray systems.

Note: The dose reduction claim is based on non-clinical (phantom) testing and on clinical testing conducted at one medical site with a specific x-ray imaging system and specific technique factors. In practice, the values of dose reduction may vary accordingly. The clinical site is responsible for determining whether the particular radiographic imaging needs are not impacted by such x-ray dose reduction. The pediatric subgroup, neonate under 1 month old, was not studied.

NoDifferencesExplanation
(1)Up to 47.5% dose reduction for abdominal radiographs of adultThe claim for dose reduction of abdominal radiographs of adult is added to the proposed devices. The proposed devices with the new IPE employing and advanced noise reduction algorithm are able to reduce x-ray dose up to 47.5% for abdominal radiographs of average adult, compared with radiation doses needed to obtain similar image quality using the old IPE on the same x-ray systems.
(2)Up to 45% dose reduction for pediatric abdomen, 15.5% for pediatric chest, and up to 27% for pediatric skull examsThe claims for dose reduction of pediatric population are added to the proposed devices. The proposed devices with the new IPE employing and advanced noise reduction algorithm are able to reduce x-ray dose up to 45% for pediatric abdomen, 15.5% for pediatric chest, and up to 27% for pediatric skull exams, compared with radiation doses needed to obtain similar image quality using the old IPE on the same x-ray systems.

B. Safety and EMC

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.

C. Non-clinical data

The quantitative assessment of image quality was conducted with the images of TOR CDR radiography phantom taken at a various exposure condition using GM85. Contrast to Noise Ratio (CNR), Detail Compacted Contrast (DCC) and Modulation Transfer Functions (MTF) of the images were measured and compared. As a result of comparison, CNR was measured highly under the condition of the new IPE in comparison with the old IPE and the other image quality metrics such as DCC and MTF of the new IPE were equivalent to those of the old IPE. The non-clinical data shows that images using the new IPE make it easy to distinguish between background and the object, and is clearer than images using the old IPE. Ant it says that the performance of the new IPE is robustness with regard to the variation of X-ray exposure factors such as kVp values and 0.1 mm Cu filter on/off.

GC85A as a representative device of the proposed devices was validated with anthropomorphic phantom images and clinical images by three and two professional radiologists respectively. Anthropomorphic phantom images captured at different radiation exposures were scored by the 5-point grading scale in consideration of anatomical regions and physical parameters. Clinical images captured at two different radiation exposures were also scored by the 5-point grading scale for the assessment of overall image quality such as sharpness and visualization for the anatomical regions.

The anthropomorphic phantom image study shows that the new IPE with an advanced noise reduction algorithm retained the quality of images captured at 47.5% reduced exposure in comparison with the old IPE. In detail, we performed a paired t-test comparison between each lower dose image and the reference image; the old IPE maintained the image quality at as low as 0.4 mGy, while the new IPE maintained the image quality at as low as 0.21 mGy. We derived the dose reduction 47.5% by calculating (0.4-0.21)/0.4*100. We confirmed that it was possible to reduce the dose in clinical images as well.

Based on the evaluation of anthropomorphic phantom images, the new IPE enables to reduce the dose of 47.5%.

ii. Pediatric population

GC85A as a representative device of the proposed devices were evaluated using a validated noise simulation tool in pursue of dose optimization with the new IPE relative to the old IPE for chest, abdomen and skull of pediatric populations.

Dose reduction performance was calculated by a statistical method based on a clinical trial. Three experienced pediatric radiologists assessed the series of dose-simulated images to decide the optimal dose for each patient. The optimal dose means the lowest dose at which image quality is still appropriate for diagnosis. On the whole, image processed by new IPE could achieve lower optimal dose than the old IPE. We analyzed the difference between the optimal doses for old IPE and new IPE images.

Based on the evaluation, the performance of the new IPE shows that the images using the new IPE taken at up to 45% reduction for pediatric abdomen. 15.5% for pediatric chest, and up to 27% pediatric skull in radiation dose are substantially equivalent of those using the old IPE without sacrificing diagnostic confidence, although dose reduction rate is various in accordance with protocols such as chest, abdomen and skull and pediatric sub-population.

E. Conclusions

There is no difference between the proposed devices and the predicate devices in technical and physical characteristics.

Differences in the devices do not alter the intended use/indications. The non-clinical and clinical data demonstrate that the proposed devices are as safe, as effective, and performs as well as the legally marketed predicate devices.
