The description focuses on the hardware and physical process of scanning and digitizing X-ray images. There is no mention of AI or ML algorithms being used for image processing, analysis, or any other function. The "Mentions AI, DNN, or ML" field is also "Not Found".
No
The device is an imaging plate scanner used for scanning and processing digital X-ray images in dental applications. It does not provide any therapeutic intervention.
Yes
Explanation: The device is designed to scan and process digital images from dental X-rays for display and storage, which are steps in the diagnostic process of visualizing and interpreting patient conditions. The "Intended Use" explicitly states it's for "scanning and processing digital images exposed on IP Imaging Plate in dental applications," which directly aids in dental diagnosis.
No
The device description clearly details hardware components such as a laser, MEMS mirror, optical sensor (PMT), LED-PCB, and plate inserts, which are integral to the device's function of scanning and processing imaging plates. While it transmits data to a computer for display and storage (software functions), the core image acquisition and processing relies on dedicated hardware.
Based on the provided information, the i-Scan Imaging Plate Scanner is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is for "scanning and processing digital images exposed on IP Imaging Plate in dental applications." This describes a process of capturing and displaying images from a physical medium (the imaging plate) that has been exposed to X-rays in vivo (within the patient's mouth).
- Device Description: The description clearly outlines a process of reading out an imaging plate that has been placed in the patient's mouth and exposed to X-rays. The device then converts the latent image on the plate into a digital image.
- Nature of IVDs: IVD devices are used to examine specimens derived from the human body (such as blood, urine, tissue) in vitro (outside the body) to provide information for diagnostic purposes. The i-Scan device does not analyze biological specimens. It processes an image created by an external energy source (X-rays) interacting with a physical medium (the imaging plate) that was temporarily placed in the body.
The i-Scan Imaging Plate Scanner is a medical device used for diagnostic imaging in dentistry, but it falls under the category of radiological imaging devices rather than IVDs.

Device Description
i-Scan Imaging Plate Scanner is a dental device that scans IP imaging plates that have been exposed in place of dental X-ray film and allows the resulting images to be displayed on a personal computer and stored for later recovery. It will be used by licensed clinicians and authorized technicians for this purpose. The device is an intraoral Plate Scanner, which is designed to read out intraoral Plates of the size 0, 1, 2 and 3. Intraoral plate scanners are state of the art since 2002 and are available in various designs from many companies around the world. The intraoral plates are put into the mouth of the patient, exposed to Xrays and then are read out with the device. The read-out-process is carried out with 651-665 nm laser. The laser beam is moved across the plate by an oscillating MEMS mirror. The laser beam stimulates the top coating of the plates, which consists of Xray sensitive material. Depending on the exposed dose, the coating emits different levels of light. These light particles are then requisitioned by an optical sensor (Photo Multiplier Tube/ PMT) and transferred into an electrical output signal is digitalized and is the data for the digital X-ray image. The data is transmitted via WIFI to a computer. Before the plate is discharged, the remaining data is erased by a LED-PCB. The user chooses which size of plate he must use and prepares the device by inserting the appropriate plate insert into the device. He then exposes the plate and then puts the plate directly into the insert by pushing it out of the light protection envelope. The user closes the light protection over and starts the read-out process. After the read out process the picture is transmitted to the connected computer, the picture can be viewed, and the IP is erased and ready to use for the next acquisition.

Discussion:
Note 1
The operating principle of scanning the image plates with a laser of approximately the same wavelength. The difference lies in scanning methodology. The subject device scans the plates with a line-by-line pattern and the predicate uses two orthogonal directional scans. The scans collect the same data and process this for visual imaging.
They support the same intended use; the differences in the mechanical design does not raise issues of safety and effectiveness.
Note 2
The subject device shows different constructive solutions for the performance itself, without influencing the intended use or safety. The operating principle is still the same. The image plates are scanned by means of that the image plate is transported in the scan position. After the scanning procedure the image plate is ejected from the device.
Note 3
The subject device offers four selections of phosphor plates whereas the predicate device is available in five sizes. This does not affect the effectiveness and the plate sizes that are offered by the subject device are the same size as the predicate device.
Note 4
The subject device displays theoretical resolutions of 10- or 33-Line Pairs per mm, whereas the predicate shows greater designation of Line Pairs per mm. The differences do not affect the operating principle and the Image Quality distinctness is such that it does not affect the effectiveness of the device.
Note 5
When the spatial frequency is lower than 3lp/mm, the MTF value is greater than 45%, and the DQE value is greater than 29%. The resolution and the quantum efficiency are both very high. Therefore, it can be considered that there is no aliasing, which is equivalent to the predicate device. When the spatial frequency is higher than 7lp/mm, the MTF value is only 5.1%, and the resolution is very low. It can be considered that there is a sign of aliasing. Coupled with the influence of quantum noise, the DQE value is less than 1%, so it does not have the ability of resolution. The difference in detective quantum efficiency was tested based on IEC62220-1 and there were minor deviations due
8
to the dental application of the radiography device. This difference did not adversely affect the image quality as demonstrated by the solid-state device testing.
Note 6
The size and weight of the subject and predicate device differ, but this has no bearing on the safety or effectiveness of the image plate scanning operations.
Note 7
The software is not the same between the subject device and the predicate, but both the subject and predicate have followed the FDA Guidance for the Content of Premarket for Submissions for Software Contained in Medical Devices. Also, both the subject and predicate have passed performance testing, demonstrating the software functions to convert the digital data to acceptable images.
