The Cefla MyRay Hyperion is intended for use in producing panoramic-ray images of the maxillofacial region. It is used for the examination of teeth, the jaw, and oral structures.
The MyRay Hyperion is a panoramic dental X-ray system which consists of a telescopic column, an overhead frame with a horizontal arm where an X-ray source and collimator and an X-ray image detector are mounted, and a console with a keyboard and display. The device includes a patient positioning system that consists of two handles which the patient grasps during exposures, a bite block, a frame for holding the head in the proper position and alignment with laser guide lights. The x-ray source and collimator generate a fan shaped x-ray beam which is projected through the patient's skull by the rotation of the imaging unit. The x-ray image detector allows reconstruction of the diagnostic image, storage of the image in the buffer memory, and transfer of the image to an external PC (not provided by Cefla).
Here's an analysis of the provided text regarding the Cefla MyRay Hyperion, focusing on acceptance criteria and study details.
Important Note: The provided document is a 510(k) summary for the Cefla MyRay Hyperion, a dental panoramic X-ray system. This type of device is an imaging modality. The typical "acceptance criteria" and "studies" you're asking about (e.g., performance metrics like sensitivity/specificity, comparison to ground truth, reader studies) are primarily relevant for AI/CAD devices that provide diagnostic interpretations or assistance.
For a standard X-ray imaging system like the Cefla MyRay Hyperion, the "acceptance criteria" are generally related to its ability to produce clear, diagnostically acceptable images and its functional characteristics meeting established safety and performance standards for medical devices. The "study" for such a device is typically a demonstration of substantial equivalence to existing predicate devices, focusing on technical specifications, image quality, and safety rather than a clinical efficacy trial with human readers.
Therefore, many of your requested points will not be directly applicable or explicitly stated in this type of submission.
Acceptance Criteria and Device Performance for Cefla MyRay Hyperion
Based on the provided 510(k) summary, the device's "acceptance criteria" for regulatory clearance are primarily demonstrating substantial equivalence to predicate devices in terms of intended use, operational characteristics, and technological characteristics, as well as meeting general safety and performance standards. The "study" proving this is the 510(k) submission itself, which compares the new device to established predicate devices.

2. Sample Size Used for the Test Set and Data Provenance
- Test Set Description: This 510(k) pertains to a medical imaging device itself, not an AI or diagnostic software. Therefore, there isn't a "test set" in the sense of a dataset of images used to evaluate diagnostic performance. The "test" for this device involved comparing its technical specifications and image acquisition capabilities to legally marketed predicate devices.
- Provenance: Not applicable in the context of diagnostic performance data. The device was manufactured in Italy.
3. Number of Experts Used to Establish Ground Truth and Qualifications
- Not Applicable (N/A): For a panoramic X-ray machine itself, "ground truth" as it applies to diagnostic accuracy of an AI algorithm is not relevant. The device's "ground truth" is its ability to produce images that are physically accurate representations of the maxillofacial anatomy, which is assessed through engineering testing and comparison to functional specifications, not expert consensus on diagnostic findings.
4. Adjudication Method for the Test Set
- N/A: No "adjudication method" for diagnostic interpretation of a test set was performed as this is an imaging device, not a diagnostic AI.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- No: An MRMC comparative effectiveness study was not done. These studies are typically conducted for AI/CAD systems to demonstrate improvement in human reader performance with aid. This submission is for an imaging acquisition device.
6. Standalone Performance (Algorithm Only without Human-in-the-Loop Performance)
- N/A: This is an imaging device, not a standalone diagnostic algorithm. Its "performance" is its ability to acquire images, not to interpret them without human intervention.
7. Type of Ground Truth Used
- Physical and Technical Specifications: The "ground truth" for this device's evaluation is primarily its adherence to established engineering, safety, and performance specifications for dental panoramic X-ray systems, as well as its ability to produce images comparable in quality to predicate devices. This includes measurements of factors like focal spot size, kVp output, detector characteristics, and image resolution.
8. Sample Size for the Training Set
- N/A: The concept of a "training set" is relevant for machine learning algorithms. This is a medical device for image acquisition, not an AI algorithm, so no training set was used.
9. How the Ground Truth for the Training Set Was Established
- N/A: As there's no training set, this question is not applicable.

{1}------------------------------------------------
imaging unit. The x-ray image detector allows reconstruction of the diagnostic image, storage of the image in the buffer memory, and transfer of the image to an external PC (not provided by Cefla). A detailed description of the components is provided below.
Telescopic Column
The telescopic column supports the patient arm at which the patient stands during X-ray exposures. It also includes the patient handles which the patient holds during imaging and a plate which contains the mid-sagittal laser beam, the bite block and chin rest. The telescopic column allows adjustment of the patient arm to the patient's height.
Overhead Assembly
The overhead assembly supports the main horizontal and rotating arm. The rotating arm holds the x-ray generator and the collimator in a fixed position opposite to the x-ray image detector.
Console
The console allows the user to select the projection mode and the exposure factors, view the machine status information, control the height of the telescopic column, adjust the reset of the Y-axis, and turn on the laser guide lights. A system emergency stop button is included on the console so the user can immediately stop the procedure.
Control Panel
The control panel serves as the user interface with the electronic control system. The layout of the controls has been designed to split the panel into 2 sections. The "Procedure programming" area is found on the left side from which the user selects the type of procedure to be performed and technical settings. The "Assisted positioning" area is found on the right side of the panel which contains the controls to move the unit to position the patient. In addition, a port for an SD card (Secure Digital Memory Card) is provided at the bottom of the control panel. If this card is inserted, the images can be saved without having to connect the unit to a computer.
Control System
The electronic components which control the system operation consist of the following:
- · Main unit- providing real-time system control as well as motor drive;
- · Power unit- connecting to the mains power supply and providing the 400 VDC bus for the system;
- · Converter unit- controlling the power to the x-ray generator;
