Intended Use
PreXion3D Explorer is intended to produce two-dimensional digital x-ray images including panoramic and cephalometric image, and three-dimensional digital x-ray images of the dental, oral, maxillofacial region, ENT (Ear, Nose and Throat) and neck region at the direction of healthcare professionals as diagnostic support for adult and pediatric patients. Cephalometric imaging also includes the hand and wrist to obtain carpus images for growth and maturity assessment.
Device Description
PreXion3D Explorer consists of a scanner, which is used for generating X-ray and detecting image data, and a Console, which is used for operating the scanner and managing the data. The scan data acquired by the scanner will be transferred to the Console. PreXion3D Explorer Image Analysis System will then perform the image analysis (2D/3D) or image edition (creating cross-section diagram, etc.), and output the image to a printer. X-ray image data is acquired while the rotation around the secured "patient's head" at a constant speed. X-rays, which are emitted from X-ray generator (built in one side of rotation arm), pass through a patient and are detected by the flat panel detector (built in the other side of rotation arm). The detected X-ray absorption data is used to process image reconstruction on the Console to create the 3D image (CT scan), the tomographic image (CT scan, CT-Panoramic scan) and Cephalometric Scan.

The document describes standard image processing and reconstruction techniques for CT and X-ray data. There is no mention of AI, ML, or related concepts like deep learning, training sets, or performance metrics typically associated with AI/ML algorithms.

No.
The device is used for diagnostic imaging, not for treating any condition.

Yes

The "Intended Use / Indications for Use" section explicitly states that the device is intended to produce digital x-ray images "as diagnostic support."

No

The device description explicitly states that the device consists of a scanner (hardware for generating X-ray and detecting image data) and a Console (hardware for operating the scanner and managing data). The performance studies also include testing related to hardware components like electrical safety, electromagnetic safety, and X-ray equipment testing.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. These tests are performed outside of the body (in vitro).
  • Device Function: The PreXion3D Explorer is an X-ray imaging system. It generates X-rays that pass through the patient's body to create images for diagnostic support. This process is performed inside the body (in vivo).
  • Intended Use: The intended use is to produce digital X-ray images of specific anatomical regions for diagnostic support. This involves capturing images of the patient's internal structures, not analyzing samples taken from the patient.

Therefore, the PreXion3D Explorer falls under the category of medical imaging devices, not In Vitro Diagnostics.

Device Description

PreXion3D Explorer consists of a scanner, which is used for generating X-ray and detecting image data, and a Console, which is used for operating the scanner and managing the data. The scan data acquired by the scanner will be transferred to the Console. PreXion3D Explorer Image Analysis System will then perform the image analysis (2D/3D) or image edition (creating cross-section diagram, etc.), and output the image to a printer.

X-ray image data is acquired while the rotation around the secured "patient's head" at a constant speed. X-rays, which are emitted from X-ray generator (built in one side of rotation arm), pass through a patient and are detected by the flat panel detector (built in the other side of rotation arm). The detected X-ray absorption data is used to process image reconstruction on the Console to create the 3D image (CT scan), the tomographic image (CT scan, CT-Panoramic scan) and Cephalometric Scan.

The operating principle of the device is as follows.

X-rays are generated by the conversion of electron kinetic energy.

Part of the kinetic energy which is generated when electrons moving at high speed are decelerated inside matter becomes the conversion source.

Use a high-voltage transformer to boost the commercial voltage (100 to 240 V) to direct current high voltage (several tens of kV) and apply it to the X-ray tube to accelerate the X-ray tube's thermal electrons, and then the X-ray will be generated.

The change in the voltage (tube voltage) and current) applied to the X-ray tube brings the following features.

· The higher the X-ray tube voltage is, the greater the penetration strength of X-rays is.

  • · The higher the current (tube current) is, the more the X-ray dose is.
    With the consideration of the above features, X-ray devices are designed to be able to control the X-ray dose and strength according to the intended use.

X-ray photography is acquired while the rotation arm is rotating around the secured "patient's head" at a constant speed.

X-rays, which are emitted from X-ray generator (built in one side of rotation arm), pass through a patient and are detected by the flat panel detector (built in the other side of rotation arm).

The detected X-ray absorption data is used to process image reconstruction on the Console to create the 3D image (CT scan) and the tomographic image (CT scan, Panoramic scan).

Based on cephalometric radiography, a plain radiographic image of the properly positioned "patient's head" between X-ray generator and flat panel detector with stable magnification ratio, can be acquired. Also, the image of "patient's hand" can be obtained.

9. Non-Clinical Performance Data

As part of demonstrating safety and effectiveness of PreXion3D Explorer and in showing substantial equivalence to the predicate device, PreXion Corporation completed a number of non-clinical The PreXion3D Explorer meets all the requirements for overall design, performance tests. biocompatibility, performance, and electrical safety results confirming that the design output meets the design inputs and specifications for the device.

The PreXion3D Explorer passed all the testing in accordance with internal requirements, national standards, and international standards shown below to support substantial equivalence of the subject device:

  • . Biocompatibility testing per ISO 10993-1, ISO 10993-5 and ISO 10993-10
  • Electrical safety testing per ABSI/AAMI ES 60601-1, IEC 60601-1-3 and IEC 60601-1-6
  • . Electromagnetic Safety testing per IEC 60601-1-2
  • . Dental extra-oral X-ray equipment testing per IEC 60601-2-63
  • . Acceptance testing of X-ray equipment per IEC 61223-3-4 and IEC 61223-3-5
  • Laser safety testing per IEC 60825-1
  • DICOM testing per NEMA PS 3.1 - 3.20
  • Usability testing per IEC 62366-1
  • . Software verification and validation per IEC 62304
  • . Storage and Transport Testing per ISO 4180

10. Clinical Performance Data

There was no human clinical testing required to support the medical device as the indications for use is equivalent to the predicate device. These types of devices, including the predicate devices, have been on the market for many years with proven safety and efficacy for the device. The non-clinical testing detailed in this submission supports the substantial equivalence of the device.

11. Statement of Substantial Equivalence

By definition, a device is substantially equivalent to a predicate device has the same intended use and the same technological characteristics as the previously cleared predicate device. Or the device has the same intended use and different technological characteristics that can be demonstrated that the device is substantially equivalent to the predicate device, and that the new device
