CBCT, panoramic x-ray imaging system with cephalostat, is an extra oral source x-ray system, which is intended for dental radiographic examination of the teeth, jaw, and oral structures, specifically for panoramic examinations and implantology and for TMJ studies and cephalometry, and it has the capability, using the CBVT technique, to generate dental maxillofacial 3D images. The device uses cone shaped x-ray beam projected on to a flat panel detector, and the examined volume image is reconstructed to be viewed in 3D viewing stations. 2D Image is obtained using the standard narrow beam technique.
RCT700 is 3D computed tomography for scanning hard tissues like bone and teeth. By rotating the c-arm which is embedded with high voltage generator all-in-one x-ray tube and a detector on each end, CBCT images of dental maxillofacial is attained by recombining data from the same level that are scanned from different angle.
Panoramic image scanning function for attaining image of whole teeth, cephalometric scanning option for attaining cephalic image, and Model Scan option for attaining dental model CBCT image are included.
The provided text describes a 510(k) premarket notification for the RCT700 dental x-ray system, which is intended for dental radiographic examinations. The submission focuses on demonstrating substantial equivalence to predicate devices, rather than proving a new device's performance against specific acceptance criteria for a novel clinical function.
Therefore, the document does not present acceptance criteria in the typical sense of a clinical trial for diagnostic performance (e.g., sensitivity, specificity, AUC) or a comparative effectiveness study with AI assistance. Instead, the "acceptance criteria" are implied by demonstrating that the new device's performance, particularly its imaging capabilities, is similar to or not worse than the predicate devices, and that it meets applicable safety and performance standards.
Here's an attempt to structure the information based on your request, acknowledging the limitations of the provided document in terms of specific acceptance criteria and detailed study designs usually associated with AI/diagnostic device performance.
1. A table of acceptance criteria and the reported device performance
The document does not specify quantitative acceptance criteria. Instead, it relies on demonstrating that the performance of the new device is "similar" to the predicate device and that all tests performed achieved "satisfactory" results. The primary performance attributes considered are related to imaging quality and safety as per relevant IEC standards.
| Acceptance Criteria Category (Implied) | Reported Device Performance | Study that Proves Device Meets Criteria |
|---|---|---|
| Imaging Quality (CBCT, Panoramic, Cephalometric) | "Similar to that of the predicate device" (for detector performance) | Bench testing according to IEC 61223-3-4 and IEC 61223-3-5. Non-clinical performance report. Clinical images were observed and verified by licensed practitioners/clinicians. |
| Safety | "Satisfactory" | Electrical, mechanical, and environmental safety testing according to IEC 60601-1, IEC 60601-1-3, IEC 60601-1-6, IEC 60601-2-63, and EMC testing according to IEC 60601-1-2. |
| Software Functionality & Safety | "Satisfactory" (Level of concern: "moderate") | Validated according to FDA guidance "Guidance for the Content d Premarket Submissions for Software Contained in Medical Devices" and "Content of Premarket Submissions for Management of Cybersecurity in Medical Devices". Risk analysis of software. |
| Patient Dosage | "Satisfies the designated tolerance" | Bench testing as part of performance testing. |
| Technical Specifications (e.g., Pixel Size, Magnification) | Comparison tables show similar or identical specifications to predicate devices. | Bench testing (implied by specification reporting). |
2. Sample size used for the test set and the data provenance
- Test Set Sample Size: The document states that "Clinical imaging samples are collected from the new detector on propose device at the 2 offices where the predicate device is installed on clinical consideration report for the clinical test images." It also mentions "random patient age, gender, and size." However, a specific number/sample size for the clinical test set is not provided.
- Data Provenance: The general statement implies the data is retrospective (collected from existing offices where the predicate device is installed) and likely from South Korea, as the manufacturer is based there and no other country is mentioned.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Number of Experts: "two licensed practitioners/clinicians"
- Qualifications: "licensed practitioners/clinicians" – specific medical specialty (e.g., dentist, radiologist) or years of experience are not specified. They observed and verified that the dental X-ray system works as intended and that "the clinical diagnosis and structures are acceptable in the region of interests."
4. Adjudication method for the test set
The document states, "As licensed practitioners or clinician diagnoses of the images, it might be proved that the clinical diagnosis and structures are acceptable in the region of interests." This suggests that the two experts independently reviewed the images and (presumably) reached a consensus or agreement that the images were clinically acceptable. However, no formal adjudication method (e.g., 2+1, 3+1) is explicitly described. It is implied that their assessment confirmed clinical acceptability.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
No, an MRMC comparative effectiveness study involving AI assistance for human readers was not performed or mentioned. The device is an x-ray imaging system, not an AI-powered diagnostic aid. This submission is about demonstrating substantial equivalence of a new imaging system incorporating new detectors, not an AI product.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
No, a standalone algorithm-only performance study was not performed or mentioned. As stated above, this is an imaging device, not an AI algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" for the clinical images appears to be expert clinical diagnosis/assessment by the "two licensed practitioners/clinicians" that "the clinical diagnosis and structures are acceptable in the region of interests" based on visual inspection of the images. No pathology or outcomes data is mentioned as ground truth.
8. The sample size for the training set
The document describes premarket notification for an imaging device, not a machine learning or AI algorithm. Therefore, no training set (in the context of AI/ML) is mentioned or applicable.
9. How the ground truth for the training set was established
As there is no training set for an AI/ML algorithm mentioned, this question is not applicable to the provided document.

CBCT, panoramic x-ray imaging system with cephalostat, is an extra oral source x-ray system, which is intended for dental radiographic examination of the teeth, jaw, and oral structures, specifically for panoramic examinations and implantology and for TMJ studies and cephalometry, and it has the capability, using the CBVT technique, to generate dental maxillofacial 3D images. The device uses cone shaped x-ray beam projected on to a flat panel detector, and the examined volume image is reconstructed to be viewed in 3D viewing stations. 2D Image is obtained using the standard narrow beam technique
"CAUTION: Federal law restricts this device to sale by or on the order of a dentist."
8. Patient population
The patient population can be the possible person who can be taken X-ray diagnostic radiation exposure.
There is no restriction for ethnic group, Gender, weight, health, or condition.
We recommend patients for x-ray diagnostic radiation exposure to be over 5 years old.
9. Operating principle
The purpose of this unit is diagnose clinical structures of a tooth and head areas mainly by using the characteristics of permeability from X-ray. The principle of formations are as following. The machine is made of X-ray generator and arms in which transfers X-ray signals to a sensor in 2D. Also, an object that has a magnification is required in a distance. Moreover, the unit has to be adjustable depending on height of a patient and PC system to reconstruct an image.
The arm parts are controlled for rotating and linear moving to synchronize between the sensor and Xray generator to get the image of interests. The purpose of this mechanism is to provide the images in Ray Co.,Ltd Page 5-3
{7}------------------------------------------------
2D or/and 3D as preferred to diagnose in a monitor. CBCT provides in 3D images as reconstructed and Panorama is to diagnose the structures in a panoramic view. Cephalometric allows for orthodontic treatment. These 3 functions could be in 1 system, Panorama with Cephalometric, or Panorama only system depending on the needs. To provide the features as mentioned above, digital transferring from permeated X-ray to absorbing to the sensor is essential and all the process are proceed in Detector. Detector transfers X-ray to light depending on the structure materials. Detector is separated into indirect method that the light is changed to digital signals on photodiode and direct method in which the light is directly transferred to digital signal. This unit is using both direct method depending on the interior structure materials.
{8}------------------------------------------------
10. Comparison with predicate device
The product is principally just the same as in the previous 510(k) #K160525.
We changed a some scan protocol from the Predicate Device(K160525). And added a CT/Pano and ceph detector to the predicate Device #K160525. But, these detectors is used predicate Device #K181452.
The compared technical features for imaging parameters, resolution, and other basic characteristics are matching very closely, and the differences are so small that they do not have any effect on performance in practice. Both devices conformance standards.

The same test protocol was used to test the performance of the subject and the predicate device for comparison. The sponsor certifies that adequate design and development controls (according to 21 CFR 820.30) were in place for manufacturing the subject device.
The differences are as follows.
- The subject device is equipped with new detectors, FXDD-0606CA, 1717SCC.
Electrical, mechanical and environmental safety testing according to standard of IEC 60601-1: 2005/AMD1:2012(3.1 Edition), IEC 60601-1-3: 2008/AMD1:2013(Second Edition), IEC 60601-1-6:2010(Third Edition) and IEC 60601-2-63: 2012(first Edition) were performed. EMC testing was conducted in accordance with the standard IEC 60601-1-2: 2014(Edition 4.0).
The software of RCT700 saves the patient and image data and offers an inquiry function, in addition, supports the image generate function intended to obtain images using the RCT700 equipment and various sensors for diagnosis. And that has been validated according to FDA "Guidance for the Content d Premarket Submissions for Software Contained in Medical Devices" and "Content of Premarket Submissions for Management of Cybersecurity in Medical Devices" to assure substantial equivalence.
The software for this device was considered as a "moderate" level of concern, since a failure or latent flaw in the software would not directly result in serious injury or death to the patient or operator.
As a result, we identified the level of concern associated with new device and provided documentation consistent with that level. Based on our risk analysis of software, the difference does not affect its safety and effectiveness.
Bench testing was conducted according to FDA Guidance "Format for Traditional and Abbreviated 510(k)s, section 18, Performance Testing - Bench"
Bench testing is used to assess whether or not the parameter measured required for describing functionalities related to imaging properties of the dental X-ray device and patient dosage satisfies the designated tolerance.
Performance (Imaging performance) testing was conducted according to standard of IEC 61223-3-4 and IEC 61223-3-5.
All test results were satisfactory.
Non-clinical considerations were conducted in accordance with FDA Guidance for the submissions of 510(k)'s for Solid State X-ray Imaging Devices".
RCT700 is equipped with FXDD-0606CA. FXDD-0606CA is a new SSXI detector, which is used to capture an image in panoramic, CBCT mode.
Based on Non-Clinical Test results of FXDD-0606CA for the subject device, is similar to that of the SiX 650HD-E for the Predicate device. And equipped with 1717SCC is a new SSXI detector, which is used to capture an image in Cephalometric. Based on Non-Clinical Test results of 1717SCC for the subject device, is similar to that of the PaxScan 4336X for the Predicate device.
{15}------------------------------------------------
All test results were satisfactory.
Clinical considerations were conducted according to FDA Guidance "Format for Traditional and Abbreviated 510(k)s, section 20".
Clinical images were provided these images were not necessary to establish substantial equivalence based on the modifications to the device but they provide further evidence in addition to the laboratory performance data to show that the complete system works as intended.
For clinical testing, two licensed practitioners/clinicians observed and verified that dental X ray system from RCT700.
The clinical imaging samples are collected from the new detector on propose device at the 2 offices where the predicate device is installed on clinical consideration report for the clinical test images. These images were gathered from the new detector installed with RCT700 on any protocols with random patient age, gender, and size. As licensed practitioners or clinician diagnoses of the images, it might be proved that the clinical diagnosis and structures are acceptable in the region of interests.
12. Conclusions
In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807 and based on the information provided in this premarket notification. RAY Co., Ltd. concludes that the newly RCT700 is safe and effective and substantially equivalent to predicate device as described herein.
