More Information

Not Found

No
The summary does not mention AI, ML, or any related terms, and the description focuses on standard digital imaging technology and performance metrics.

No
The device is used for radiographic examination to assist in diagnosing diseases, which is an imaging and diagnostic purpose, not a therapeutic intervention.

Yes
The "Intended Use / Indications for Use" states that the device is used "to assist in the diagnosing of diseases of the teeth, jaw and oral structures."

No

The device description explicitly states that the WeSensor comprises three components, including an intraoral digital X-ray sensor and a sensor holder, which are hardware components.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • WeSensor Function: The WeSensor is an intraoral digital x-ray sensor. It captures radiographic images of teeth, jaw, and oral structures. This is an in vivo (within the living body) imaging process, not an in vitro test on a sample.
  • Intended Use: The intended use is for a radiographic examination to assist in diagnosing diseases based on the visual information from the X-ray images.

The device is a medical imaging device used for diagnostic purposes, but it does not fit the definition of an In Vitro Diagnostic.

Device Description

The WeSensor is an intraoral digital x-ray sensor. It comprises three components: (1) an intraoral digital X-ray sensor which connects to a PC via a USB port; (2) WeSensor Software package; and (3) a sensor holder as an accessory.

The sensor part of WeSensor comes in four distinct models according to active area size and scintillator type: G350A, F350A, G150A, and F150A. Both 'G' models (G350A and G150A) use a scintillator made from Gadolinium Oxysulfide (Gd2O2S:Tb), and there is no filter layer in these models. Both 'F' models (F350A and F150A) use a different type of scintillator made from Thallium-doped Cesium Iodide (Csl:Tl) and Sodium Iodide (NaI:T1). These models also include an extra filter layer in the sensor. This unique structure of the scintillator and filter layer further enhances image quality. And model 350 having a larger active area than model 150.

There is no electrical or physical connection between the x-ray generator. Images are automatically acquired when x-rays are present in a dose which is perceptible to the sensor. An X-ray image sensor is positioned in the patient's mouth just like Intra-oral film. Digital x-ray images are quickly displayed on the screen. Images can be optimized for viewing via imaging software, stored as image files.

PICOPACK offers technical support for this device to ensure proper operation and to answer any questions regarding the function of the device. The type of x-ray systems that integrate with the G350A/F350A/G150A/F150A are wall-mounted x-ray 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, all will control the exposure time.

This 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. G350A/F350A/G150A/F150A must be connected to a PC through the standard USB 2.0 port.

The WeSensor Viewer is a software component designed to be operated within Windows Desktop environment for medical device acquisition, storage, transmission along with simple editing functions. Using Picopack's provided SDK in local settings allows users to connect this software directly to an oral sensor for X-ray image acquisition and patient image viewing. This software has moderate level of concern and this software has not been previously FDA-cleared with other similar detectors.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Sensor performance testing and software function test have been undergone for the WeSensor intraoral digital x-ray detector. The successful test results including max.image resolution, DQE, and MTF indicate that the subject device performance is comparable to or exceed those of the predicate devices. Also, clinical images were examined by Dr.Park, a qualified dentist in the state of Nevada. The results demonstrated no significant difference in diagnosing dental diseases between the subject device and the predicate device.

Performance Data

Sensor performance testing and software function test have been undergone for the WeSensor intraoral digital x-ray detector. The successful test results including max.image resolution, DQE, and MTF indicate that the subject device performance is comparable to or exceed those of the predicate devices. Also, clinical images were examined by Dr.Park, a qualified dentist in the state of Nevada. The results demonstrated no significant difference in diagnosing dental diseases between the subject device and the predicate device.

Electrical Safety and EMC

Non-clinical test was performed in accordance with the following international standards,

  • IEC 60601-1:2012 ed.3.1 -
  • IEC 60601-1-6 Edition 3.1 2013-10 Medical Electrical Equipment Part 1-6: General -Requirements for Basic Safety and Essential Performance - Collateral Standard: Usability
  • IEC 60601-1-2 Edition 4.0 2014-02 Medical Electrical Equipment Part 1-2: General -Requirements for Basic Safety and Essential Performance - Collateral Standard: Electromagnetic Disturbances - Requirements and Tests
  • ANSI AAMI IEC 62304:2006+AMD1:2015 Medical Device Software Software Life -Cycle Processes
  • EN ISO 14971:2012 Medical devices Applications of risk management to medical devices
  • ANSI AAMI IEC IEC 62366:2007 Medical devices Part 1: Application of usability engineering to medical devices

Conclusion

The subject device is substantially equivalent with the predicate device in the areas of indications for use, intended use, general functions & features, principle of operation, and technological characteristics. The new device does not introduce fundamentally new scientific technology. Therefore, we conclude that the subject device described in this submission is substantially equivalent to the predicate device.
