Intended Use
PreXion3D Expedition 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. This device is not intended for use on patients less than approximately 21 kg (46 lb) in weight and 113 cm (44.5 in) in height; these height and weight measurements approximately correspond to that of an average 5 year old.
Device Description
PreXion3D Expedition 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 Explore Image Analysis System will then perform the image analysis (2D/3D) or image edition (creating crosssection diagram, etc.), and output the image to a printer. X-ray image data 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), the tomographic image (CT scan, Panoramic scan) and Cephalometric Scan.
More Information

No
The summary describes standard image reconstruction and analysis techniques for CT scans and other X-ray modalities, with no mention of AI or ML algorithms.

No
The device is described as producing diagnostic images and imaging data (two-dimensional and three-dimensional digital x-ray images) for diagnostic support. It does not mention any therapeutic capabilities or functions.

Yes
The "Intended Use / Indications for Use" section explicitly states that the device is for "diagnostic support".

No

The device description explicitly states it consists of a scanner (hardware for generating and detecting X-rays) and a console (hardware for operating the scanner and managing data), in addition to the software for image analysis. This indicates it is a hardware-software system, not a software-only device.

Based on the provided information, 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.
  • Device function: The PreXion3D Expedition is an X-ray imaging device that produces images of the body (dental, oral, maxillofacial, ENT, neck, hand, and wrist) using radiation. It does not analyze samples taken from the body.
  • Intended Use: The intended use is to produce digital x-ray images as diagnostic support, which is a function of medical imaging devices, not IVDs.

The device is a medical imaging device used for diagnostic purposes, but it operates by capturing images of the body directly, not by analyzing samples in a laboratory setting.

Device Description

PreXion3D Expedition 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 Explore Image Analysis System will then perform the image analysis (2D/3D) or image edition (creating crosssection diagram, etc.), and output the image to a printer.

X-ray image data 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), the tomographic image (CT scan, 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 (tube 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.

The software is unchanged from the predicates in terms of function.

  • Software Level of Concern -
    The software level of concern for the PreXion3D Expedition is Moderate. The rationale is as follows:

Even prior to mitigation of hazards, there is no risk of serious injury or death associated with this software. Excessive X-ray irradiation can be considered as a risk of serious injury, but it is limited in scope by a hardware timer. A hardware activated buzzer indicating exposure and an emergency switch are also provided. As such, there is a risk of injury associated with the software, but not serious injury.
