ENGLISH
1. System Overview
The VEX-P300, a portable dental X-ray system, operates on 22.2 V d.c. supplied by a
rechargeable Li-ion polymer battery pack. The portable X-ray system is an X-ray
generating device which is mainly designed for dental examination (teeth and jaw).
The portable X-ray system is composed of an X-ray generating part with an X-ray tube
including a device controller, a power controller, a user interface, a beam limiting part,
a backscatter shield, and an optional Remote Exposure Switch. The VEX-P300 is
designed to diagnose teeth and jaw through X-ray exposure using intra-oral image
receptors.
1.1 Indications for Use
The VEX-P300 is a portable dental X-ray 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.
1.2 Principles of Operation
X-rays are emitted when high voltage is supplied to the X-ray tube assembly which
frees electrons from cathode. They hit anode to produce X-rays. The equipment
acquires images by emitting X-rays continuously on human tooth.
