3. System Overview
The
EzRay Air Wall (VEX-S300W)
is an intra-oral dental X-ray system intended for
intra-oral imaging. It consists of an X-ray generator, an X-ray controller, a beam limiting
device, an operation panel, and a mechanical arm. The X-ray controller allows for
accurate exposure control, and the adjustable mechanical arm allows for easy
positioning. The system can be used with an imaging system.
3.1 Indications for Use
The EzRay Air Wall (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.
3.2 Principles of Operation
X-rays are emitted when a high voltage is supplied to the X-ray tube assembly, which
frees electrons from the cathode. They hit the anode to produce X-rays. The
equipment acquires images by emitting X-rays continuously on the human tooth.
