The summary describes a 3D reconstruction algorithm based on tomosynthesis, which is a standard image processing technique, not explicitly AI/ML. There is no mention of AI, ML, or related terms like deep learning or neural networks in the document.
No.
Explanation: The device is described as an X-ray system for producing diagnostic dental radiographs for diagnostic purposes, not for treating conditions.
Yes
The "Intended Use / Indications for Use" section explicitly states that the system is "for producing diagnostic dental radiographs" and "provides 3D imaging for diagnostic purposes."
No
The device description explicitly states it includes an extraoral X-ray source, a custom digital sensor, and a server, all of which are hardware components.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information about a person's health.
- Lumos 3DX System Function: The Lumos 3DX System is an imaging device that uses X-rays to create images of the teeth, jaw, and other oral structures within the patient's body. It does not analyze samples taken from the body.
The description clearly states that the system is an "extraoral X-ray source (intraoral X-ray detection) dental X-ray system for producing diagnostic dental radiographs". This is a form of medical imaging, not in vitro diagnostics.

Device Description
The Lumos 3DX system is a 3D dental chairside X-ray system on a mobile stand that uses tomosynthesis (limited-angle tomography) to generate 3D images of the teeth and surrounding structures. A custom digital sensor is placed in the patient's mouth and multiple images are acquired around an arc of rotation and then fed into a 3D reconstruction algorithm.
The digital sensor provided with the system is specifically for use with the Lumos 3DX device. The sensor has a higher frame rate that enables the Lumos 3DX system to capture 30 images in a short period of time.
A server is provided as part of the Lumos 3DX system and wirelessly connects to one or more Lumos 3DX systems. After capturing images, the Lumos 3DX wirelessly transfers them to the server for reconstruction. This server can then be connected to the local network for access of the reconstructed data.

Description of the test set, sample size, data source, and annotation protocol
The effect of patient motion was evaluated to verify that typical movements induced by a patient during imaging do not significantly affect the system or the resulting 3D volume. The results of the patient motion studies justify the use of dental phantoms and cadaver subjects for the analysis of clinical image quality.
In addition to the image quality bench studies, system verification and validation testing including hazard mitigation has been performed to demonstrate the Lumos 3DX meets design input and user needs.
The Lumos 3DX has been tested to show compliance with the applicable IEC series of x-ray performance standards, including IEC60601-2-65. It also meets all applicable 21CFR Subchapter J performance standards including those for radiation safety, such as dosimetry, leakage, and stray radiation.
The clinical utility of the Lumos 3DX was demonstrated by performing a Clinical Imaging Evaluation with dental professionals. Dental phantoms with human teeth and simulated bone as well as Cadaver subjects were selected to represent typical use cases for the Lumos 3DX. A number of 3D images were obtained for analysis and review.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Bench and Radiation Safety Testing Summary: An Image Quality Performance test was completed using image quality phantoms for spatial resolution, contrast, and noise. The 3D volume voxel size was also verified.
Clinical Image Quality Testing Summary: The clinical utility of the Lumos 3DX was demonstrated by performing a Clinical Imaging Evaluation with dental professionals. Dental phantoms with human teeth and simulated bone as well as Cadaver subjects were selected to represent typical use cases for the Lumos 3DX. A number of 3D images were obtained for analysis and review.
Based on the evaluations made by the dental professionals, the images obtained with the Lumos 3DX were of diagnostic quality for clinical use.

| Leakage
Radiation | The Lumos 3DX and predicate device both allow for viewing slices, but the thickness is much smaller in the Lumos 3DX system which allows for a more detailed viewing process for the dental professional. In addition, because the Lumos 3DX takes images around a circle rather than along a single plane it provides more spatial information for reconstruction. The Portray System is a wall-mounted system while the Lumos 3DX system is on a stand, but both have articulating arms. In both systems, an alignment aid is used to hold the detector in the correct position relative to the x-ray source and that alignment aid is magnetically attached to the front of the nose cone.
In dental imaging Panoramic and Cone Beam CT systems are used to obtain 3D images of patient's oral structures. This is possible because the x-ray source and detector are external and rotate around the patient's head. These systems are large and expose the patient to a significant amount of radiation. The Lumos 3DX system is a smaller system that can take images of a more focused area using less radiation. Its portability also allows it to be used for unconscious patients while they lay in the chair rather than needing to move them to the x-ray device.

Dental phantoms with human teeth and simulated bone as well as Cadaver subjects were selected to represent typical use cases for the Lumos 3DX. A number of 3D images were obtained for analysis and review.
Based on the evaluations made by the dental professionals, the images obtained with the Lumos 3DX were of diagnostic quality for clinical use.
- Based on successful verification and validation testing, conformance to recognized Conclusion: performance standards and FDA guidance, and development under the 3Dio Quality Management System, we conclude that the Lumos 3DX Imaging System is substantially equivalent to the predicate device Surround Medical, Portray System (K211014) and is safe and effective for its intended use.
