Intended Use
Digital image scanner of dental is intended to be used for scanning and processing digital images exposed on IP Imaging Plate in dental applications.
Device Description
Digital image scanner of dental 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 the screen 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 S0, S1, S2 and S3. The intraoral plates are put into the mouth of the patient, exposed to X-rays and then are read out with the device. The read-out-process is carried out with 630-645 nm laser. The laser beam is moved across the surface of the plate by an oscillating mirror. The laser beam stimulates the top coating of the plates, which consists of X-rays 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. This signal is digitalized and is the data for the digital X-ray image. 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 screen, the picture can be viewed, and the IP is erased and ready to use for the next acquisition.
More Information

None

No
The description focuses on the hardware and basic image processing steps (scanning, digitalization, display, storage, erasure). There is no mention of AI/ML algorithms for image analysis, interpretation, or enhancement beyond standard digital processing. The performance studies also do not mention any AI/ML-specific validation.

No.
The device is an image scanner used to digitize dental X-ray images from imaging plates for display and storage. It does not provide any direct therapeutic benefit to the patient.

No.

This device is an image scanner that processes digital images exposed on IP Imaging Plates, essentially digitizing X-ray films. It does not analyze or interpret these images to provide a medical diagnosis; its function is solely to produce the image for a clinician to then interpret.

No

The device description clearly outlines hardware components such as a laser, oscillating mirror, optical sensor (PMT), LED-PCB, and plate inserts, which are integral to the device's function of scanning and processing images from IP Imaging plates. While it includes software for image processing and control, it is not solely software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health. This testing is done outside the body (in vitro).
  • Device Function: The described device is a digital image scanner that reads X-ray images captured on imaging plates placed in the patient's mouth. It processes these images for display and storage.
  • No Specimen Analysis: The device does not analyze any biological specimens taken from the patient. It processes images generated by an external energy source (X-rays) interacting with the patient's anatomy.

Therefore, the device's function falls under the category of medical imaging equipment, not In Vitro Diagnostics.

Differences between New device and Predicate Device:

Note 1:

The weight, dimensions and appearance of the proposed device differ slightly from the predicate device,depending on the design and sales requirements of these differences are insignificant in terms of safety or effectiveness.

Note 2:

The operating principle of scanning the image plates with a laser of approximately the same wavelength,both the proposal device and the predicate device scans the plates with a line-by-line pattern. The scans collect the same data and process this for visual imaging. They support the same indications for use; the differences in the mechanical design does not raise issues of safety and effectiveness.

Note 3:

The subject device displays theoretical resolutions of 17-Line Pairs per mm, whereas the predicate shows theoretical resolutions of 10- or 33-Line Pairs per mm. And the image resolution of the proposed device is between the image resolution of the predicate device. 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 4:

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.

Note 5:

According to the latest requirements, IEC 6220-1 is not applicable to digital X-ray imaging equipment for dental radiography. IEC 61010-1 is the test for laboratory equipment, we have done the test for ANSI AAMI ES60601-1, the standard is more stringent than IEC 61010-1.Other tests are the same as the predicate equipment, so it does not cause safety problems.
