1. System Overview
The EzRay Air Wall (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,

exposure control, and the adjustable mechanical arm allows for easy positioning. The
system can be used with an imaging system.
1.1 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.

frees electrons from cathode. They hit anode to produce X-rays. The equipment
acquires images by emitting X-rays continuously on human tooth.
