The Panoura X-ERA PF/NF/MF dental panoramic and cephalometric device is intended for dental radiographic examinations of teeth, jaw and TMJ areas by producing conventional 2D X-ray images as well as X-ray projection images of examined volume for the reconstruction of 3D view. The device must only be operated and used by dentists and other legally qualified professionals.
Panoura X-ERA PF/NF/MF consists of a scanner, which is used for generating X-ray and detecting image data, and a Console, which is used for operating the scanner and managing the data. The scan data acquired by the scanner will be transferred to the Console. The Console is new software and classified as moderate level concern. 3D Viewer will then perform the image analysis or image edition such as creating cross-section diagram.
3D sensor is not installed for Panoura X-ERA PF. Medium FOV sensor is installed for Panoura X-ERA NF. Large FOV sensor is installed for Panoura X-ERA MF.
The provided text is a 510(k) summary for the Panoura X-ERA PF/NF/MF dental panoramic and cephalometric device. It focuses on demonstrating substantial equivalence to a predicate device (IMAGEWORKS PANOURA, K122806).
Crucially, this document does not contain information about acceptance criteria for an AI-powered device, nor does it describe a study specifically proving an AI device meets such criteria.
The "Panoura X-ERA PF/NF/MF" is an extraoral source x-ray system, a hardware device for capturing dental images. While it "consists of a scanner... and a Console, which is used for operating the scanner and managing the data. The Console is new software and classified as moderate level concern. 3D Viewer will then perform the image analysis or image edition such as creating cross-section diagram," this software appears to be purely for imaging acquisition, management, and basic viewing/editing, not for AI-driven diagnostic or analytical capabilities. The key changes mentioned are software and the addition of a 3D sensor.
The "studies" mentioned are "Bench Testing" which compared test pattern images and confirmed conformity with various IEC standards (electrical safety, radiation safety, laser safety). Software validation was done according to "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices," which is a general guideline for medical device software, not specific to AI performance.
Therefore, I cannot fulfill your request to describe the acceptance criteria and the study that proves an AI device meets the acceptance criteria, as this document describes a traditional imaging hardware device with associated operational software, not an AI product.
If you have a document specific to an AI medical device, I would be happy to analyze it for the requested information.

PREXION3D ECLIPSE is intended to produce two-dimensional digital panoramic and cephalometric images, and three-dimensional digital X-ray images of the dento-maxillo-facial region at the direction of healthcare professionals as diagnostic support.
The PREXION3D ECLIPSE consists of scanner and two software including Console software, and Viewer software used for the Image Analysis System and Data processing. A qualified computer named Console computer is distributed with the PREXION3D ECLIPSE.
The PREXION3D ECLIPSE uses the Image Analysis System and the processed data acquired by the scanner to analyze 2D and 3D images, perform image edition, such as creating cross-section views, and output results to a printer or other output device.
During scanning, X-rays are generated from the X-ray tube head mounted in the arm of the scanner and the X-rays passing through a patient are then detected by the flat panel detector of the scanner under the control of the firmware and the Console software installed on the qualified computer. The detected X-ray absorption data is processed by the Console software and viewer software on each computer to reconstruct images. Scanning is performed using X-ray penetration signals of a patient taken from multiple directions to produce two-dimensional and three-dimensional digital X-ray images of the dento-maxillo-facial region for the diagnosis of hard tissue
The PREXION3D ECLIPSE performs three types of scanning including CT scan generating two (2) or three (3) dimensional images, Panoramic scan generating two (2) dimensional images and Cephalometric radiography generating a plain radiographic image.

The PANOURA 18S dental panoramic and cephalometric device is intended for dental radiographic examinations of teeth, jaw and TMJ areas by producing conventional 2D X-ray images as well as X-ray projection images. The device must only be operated and used by dentists and other legally qualified professionals.
The PANOURA 18S dental panoramic and cephalometric device is intended for dental radiographic examinations of teeth, jaw and TMJ areas by producing conventional 2D X-ray images as well as X-ray projection images. The PANOURA 18S is equipped with an X-ray generator and a Sensor unit at Arm unit supported by Column unit and Sliding body unit. While rotating around the patient's teeth and jaw, the PANOURA 18S irradiates X-ray and detects X-ray absorbed data at the Sensor unit multiple times. Detected multiple data are transferred to an image processing unit and the data are superimposed with appropriate shift value according to the X-ray moving speed from the arm rotation to acquire image.
The Panoura 18S is an extraoral x-ray system, which is a medical device and not an AI/ML algorithm. The provided documentation does not contain information about acceptance criteria or a study proving the device meets those criteria in the context of AI/ML performance. Instead, the document focuses on demonstrating substantial equivalence to a predicate device (ORTHOPANTOMOGRAPH K093683) by comparing technical, operational, and intended use characteristics, and compliance with recognized consensus or voluntary standards for medical electrical equipment and radiation protection.
Therefore, I cannot provide the requested information regarding AI/ML acceptance criteria and performance studies. The provided text describes a traditional medical device submission, not an AI/ML-driven one.

FineCube is an x-ray device (cone beam computed tomography) that acquires a single 360 degree rotational sequence of the head and neck areas, including the ENT and dentomaxillofacial area for use in diagnostic support. The device is operated and used by physicians, dentists, and x-ray technologists.
The FineCube consists of two main elements: (1) The X-Ray generation and acquisition system and (2) the image analysis software. The X-Ray generation/acquisition system creates a cone-shaped x-ray field which is acquired on a flat panel sensor with a resolution of 608 x 616 x 200 um. FineCube is an X-ray imaging device that constructs a three dimensional model from images taken during a rotational X-ray sequence. FineCube is intended to be used whenever a dentist, oral surgeon, or other physician needs 3D information of high contrast objects
The provided 510(k) summary for the FineCube Dental CT System (K063622) does not contain detailed information about acceptance criteria and specific studies demonstrating the device meets those criteria. Instead, it focuses on establishing substantial equivalence to predicate devices based on indications for use and specification comparisons.
Here's a breakdown of the available information and what is missing based on your request:
1. Table of Acceptance Criteria and Reported Device Performance
Not available in the provided document. The 510(k) summary only provides a table comparing the specifications of the FineCube with two predicate devices. It doesn't list defined "acceptance criteria" for performance metrics like image quality, diagnostic accuracy, or specific measurements, nor does it present the FineCube's performance against such criteria. The document states "The results of bench, test laboratory and clinical testing indicates that the new device is as safe and effective as the predicate devices," but no specific performance data or statistical analysis is provided to support this claim against defined criteria.
2. Sample Size Used for the Test Set and Data Provenance
Not explicitly stated in the document. The document mentions "bench, test laboratory and clinical testing," but does not provide details on the sample sizes used for these tests or the provenance (country of origin, retrospective/prospective) of any clinical data.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Experts
Not available in the provided document. There is no information regarding the establishment of ground truth by experts for any testing conducted.
4. Adjudication Method for the Test Set
Not available in the provided document.
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
Not applicable. The FineCube is an imaging device (cone beam computed tomography) and not an AI-powered diagnostic algorithm designed to assist human readers. Therefore, an MRMC comparative effectiveness study involving AI assistance would not be relevant to this device's submission.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is not an AI algorithm. It is a medical imaging device.
7. The Type of Ground Truth Used
Not available in the provided document.
8. The Sample Size for the Training Set
Not applicable. As a medical imaging device, the concept of a "training set" in the context of machine learning algorithms is not directly relevant. The device undergoes engineering and performance validation rather than algorithmic training.
9. How the Ground Truth for the Training Set was Established
Not applicable, as there is no "training set" in the machine learning sense for this device.
Summary of what is available and what is missing:
The 510(k) summary for K063622 primarily relies on demonstrating substantial equivalence to predicate devices through a comparison of their indications for use and technical specifications. While it generally asserts that safety and effectiveness were demonstrated through "bench, test laboratory and clinical testing," it lacks the specific details requested regarding acceptance criteria, study methodologies, sample sizes, ground truth establishment, expert involvement, or any data related to AI performance metrics. This level of detail is often not included in the public 510(k) summary and would typically be found in the complete 510(k) submission that is reviewed by the FDA.
