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.

AI/ML Overview

The FDA 510(k) summary for the PreXion3D Expedition describes the device and its claimed substantial equivalence to predicate devices, but it does not contain the detailed information necessary to answer the questions about acceptance criteria and the study that proves the device meets them. This document is a regulatory filing, primarily focused on demonstrating substantial equivalence based on technical characteristics and intended use, rather than providing a detailed performance study with specific acceptance criteria and outcome metrics for AI/ML components.

Specifically, the document states: "No clinical testing was performed and that the non-clinical testing provided in this submission supports the substantial equivalence of the device." This confirms that there was no performance study of the kind typically used to evaluate AI model performance (e.g., assessing diagnostic accuracy against ground truth).

Therefore, I cannot extract the requested information from the provided text. The tables and sections related to "Technological Characteristics and Performance" are comparing device specifications (e.g., X-ray generation, detector types, physical dimensions) to predicate devices, not reporting on the performance of an AI component against specific diagnostic acceptance criteria.

To answer your questions, one would typically need access to a detailed clinical validation study report for an AI-powered diagnostic device, which is not present in this 510(k) summary.

7. 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.

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.

Image /page/5/Picture/1 description: The image shows the logo for PreXion. The logo features the company name in a light gray, elegant font, with the tagline "make IT visible" underneath in a smaller font. Above and to the right of the name is a stylized, curved graphic in blue and gray, adding a modern touch to the overall design.

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 chanqe 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).

Cephalometric Exposure ।

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.

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 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 imaqe 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.

Above and behind the name is a stylized graphic of two curved lines, one in blue and one in gray, creating a sense of movement or technology.

For CT and Panoramic scan, the detected data is reconstructed using filtered-back-projection method. In the case of Cephalometric scan, the acquired 2D data is output as it is.

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.
