EzRay Air W
The EzRay Air W (Model: VEX-S300W) is an intra-oral dental X-ray system (extra-oral X-ray source system) intended for use by a trained and qualified dentist or dental technician for both adult and pediatric subjects for producing diagnostic dental radiographs for treatment of diseases of the teeth, jaw, and other oral structures using intra-oral image receptors.
The EzRay Air W (Model: VEX-S300W) is an intra-oral dental X-ray system intended for intra-oral imaging, It consists of X-ray generator, X-ray controller, beam limiting device, operation panel and mechanical arm. The Xray controller allows for accurate exposure control, and the adjustable mechanical arm allows for easy positioning. The system can be used with an imaging system.
The provided text describes a 510(k) premarket notification for the EzRay Air W (Model: VEX-S300W) intra-oral dental X-ray system. This document is focused on demonstrating substantial equivalence to a legally marketed predicate device rather than undergoing extensive clinical trials or performance studies that would typically involve acceptance criteria for an AI-powered device.
Therefore, the information requested, particularly regarding acceptance criteria for an AI device, sample sizes for test and training sets, expert ground truth establishment, MRMC studies, and standalone performance, is not applicable to this submission. This is a submission for an X-ray imaging device itself, not an AI or software device that processes images.
However, I can extract the available performance information related to the device's technical specifications and how its performance was compared to the predicate device.
