The description focuses on the hardware (CMOS sensor, sizes, scintillator) and basic image acquisition and transfer via USB. It mentions image processing via separate software (not part of the submission) but does not describe any AI/ML capabilities within the submitted device itself. The "Mentions AI, DNN, or ML" field is also "Not Found".
No.
The device is used for acquiring X-Ray images, which is a diagnostic function, not a therapeutic one. It receives X-rays but does not generate or apply any treatment.
Yes
The device is described as an "Acquisition of intraoral X-Ray image of the human dental arch" device. Acquiring images to inform a diagnosis falls under the definition of a diagnostic device.
No
The device description clearly states that the device is a "digital intraoral sensor based on CMOS technology" and describes physical components like "active area 20 x 30 mm" and "USB connection." This indicates it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is the "Acquisition of intraoral X-Ray image of the human dental arch." This is a medical imaging device used to capture images of anatomical structures.
- Device Description: The device is a digital intraoral sensor based on CMOS technology for acquiring X-ray images. It's a receiver of X-rays, not a device that analyzes biological samples or performs tests on them.
- No mention of biological samples or analysis: The description focuses entirely on the acquisition of X-ray images of the dental arch. There is no mention of analyzing blood, urine, tissue, or any other biological sample.
- Input Imaging Modality: The input is X-Ray, which is a physical imaging modality, not a method for analyzing biological samples.
- Anatomical Site: The anatomical site is the "human dental arch," which is a physical structure, not a biological sample being tested.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device's function is to capture images for visual interpretation by a healthcare professional, not to perform in vitro analysis of biological samples.

Intended Use / Indications for Use
Acquisition of intraoral X-Ray image of the human dental arch. In particular:
• The STARX-1/ STARX PRO-1 sensors (active area 20 x 30 mm) allow to acquire the majority of intraoral images both vertically and horizontally.
· The STARX-2/ STARX PRO-2 sensors (active area 26 x 34 mm) allow to acquire horizontal bitewing images.

Device Description
The StarX-1, StarX-2, StarX PRO-1 and the StarX PRO-2 are digital intraoral sensors based on CMOS technology for intraoral X-Ray image acquisition of the human dental arch. The sensors are available in two sizes; in particular:
- . StarX-1 / StarX PRO-1 sensors: active area 20 x 30 mm
- . StarX-2 / StarX PRO-2 sensors: active area 26 x 34 mm
The differences between the sensors are the sizes and the different kind of scintillator (Cesium lodide - Csl and Gadolinium Oxysulfide - GOS).
StarX-1, StarX-2, StarX PRO-1 and StarX PRO-2 are directly connected to the acquisition PC through the USB connection. Up to three sensors can be connected to one PC at time.
The type of X-ray systems that integrate with the sensors are wall-mounted Xray intraoral generators (both AC and DC) with a tube current between 1 and 15 mA inclusive, and with a tube voltage between 50 and 100 kV inclusive, with in-built controls to set exposure parameters. Generators allow variable mA/kV to be selected, which will control the exposure time.
The sensor is supplied with an acquisition (TWAIN) module to acquire images from the sensor via the USB. The user can further process these images via a patient management software to process, filter and modify images using a software such as the Oris Win DG software which is not part of this submission.
The device cannot act as an x-ray generator controller. All control of x-ray generation is done by controls built into the generator itself. There is no connection between the subject device and the x-ray generator. The subject device does not control the generator, it is a receiver only.

Substantial Equivalence:
The subject device and predicate device are identical in firmware/hardware and supplied by the same company, Hamamatsu. The firmware in the FONA devices has already been cleared in the Predicate Device.
The sensor technology and principle of operation remain the same. The FONA StarX-1 and StarX-2 utilise the GOS scintillator which work on similar principles as the CSi scintillator found in the StarX PRO and the predicate devices. Clinical as well as the Non-Clinical testing performed on these FONA devices do not raise any concern of safety or effectiveness as compared to the predicate device.
The predicate device comes with Xray Vision (OTS package from Apteryx, USA) which performs image acquisition, archiving, image enhancements, electronic transmission and diagnostic review system.
The FONA sensor is supplied only with an acquisition (TWAIN) module to acquire images from the sensor via the USB. The user can further process these images via a patient management software to process, filter and modify images using a software such as the Oris Win DG software which is not part of this submission.
A comparison of the FONA sensors to the predicate device is tabulated below:

The comparison table reveals there are no new technical issues of safety or effectiveness raised by the substitution of the scintillator. Professional evaluation of imaging samples were found to be of good quality, high resolution, clinically acceptable and substantially equivalent to the predicate device.
Summary of Non Clinical Testing: IEC standards have been employed for Electrical Safety, Electromagnetic Compatibility, performance and usability. The panel power supply is UL Listed. The CMOS area image sensor manufacturer conducted performance testing according to the FDA quidance document for solid state digital X-ray panels. Risk Analysis and System operation verification tests were conducted in accordance with FDA guidance documents. Labelling was developed to comply with the FDA solid state panel guidance document.
Summary of Clinical Testing: Sample clinical images from the FONA device were evaluated as per the FDA guidance document for solid state digital X-ray panels and found to be clinically adequate.
Conclusion: After analysing non-clinical data, electrical safety as well as clinical evaluation, it can be concluded that the FONA devices are as safe and effective as the predicate device, has few technological differences, and has no new intended use, thus rendering it substantially equivalent to the predicate device.
