1. Introduction

1.1. System Description

EzSensor is a modern digital imaging solution for intraoral dental radiography. Its advanced CMOS

technology provides excellent image quality. For patient comfort, the EzSensor’s ergonomic design is

based on human intraoral anatomy.

EzSensor is a digital X-ray imaging system designed specifically for dental radiography within the oral cavity.

The system captures X-ray images and makes them available for display and storage across your network

of computers.

EzSensor is connected by a ‘USB A-A’ cable (supplied separately) to a compatible Console PC. The

Console PC runs Windows XP or Windows Vista and also provides power for the device.

Support for the EzSensor is provided by compatible software programs such as EasyDent V4. For other

custom applications, a programmer’s guide is available.

The EzSensor includes a detachable holder that can be mounted to a wall or other stable surface.

EzSensor is available in two sizes(1.5 and 1.0). Size 1.0 is suitable for children, while size 1.5 is appropriate

for adult patients.

● Excellent image quality based on advanced CMOS technology

● Optimized sensor shape for human oral structure

● Low-dose performance

● Easy-to-use USB 2.0 interface

4.1. Visual Inspection

Like all electrical systems, EzSensor requires not only correct usage, but also visual inspection prior to

operation, Along with routine checks at regular intervals. These precautions will help ensure that the system

operates accurately, safely, and efficiently.

Before using, the operator should check the system for any signs of physical damage or defect. If

something is detected, contact your local distributor of VATECH & E-WOO products for further instructions

on what to do.

4.2. Periodic Maintenance

Periodic maintenance should be performed if needed, but at least once a month. It must consist of various

checks performed by the operator or by a qualified service technician.

● Check that all cables connected to the EzSensor are undamaged

● Check for external damage to the EzSensor that could compromise its ability to operate safely.

4.3. Cleaning

To clean the EzSensor, use either of the following solutions listed below and observe the noted precautions.

● Mild soap and water

● Isopropyl alcohol (70%)

Do not soak or immerse the system and be sure to dry it completely afterwards.

Clean the surface of the system by moistening it with a soft cotton swab dipped in either of the cleaning

solutions listed above. Gently wipe the surface from end-to-end in lines without applying pressure. Make

sure that the liquid will not penetrate the system through the USB cable or the sensor cable connectors.

After cleaning the surface of the EzSensor, use a clean lint-free cloth to dry the system, as needed, until the

surface is clean.

5. Warranty

The EzSensorTMis warranted to be free from sensor defects in sensor and workmanship from the date of

installation for a period of 12 months.

In the event that the product is returned by the dealer or the end-user after the warranty has expired, we

reserve the right to collect a reasonable fee from the end user for services mutually agreed upon.

Any item returned to the factory, through an authorized dealer VATECH & E-WOO, will be repaired or

replaced at our option at no charge provided that our inspection indicates it to have been defective.

Dealer’s labor cost, shipping and handling charges are not covered by this warranty.

This warranty does not apply to damages due to shipping, misuse, or careless handling. Warranty is void if

the system is installed, repaired, or serviced by anyone other than authorized service personnel, as dictated

by VATECH & E-WOO.

Appendix

The X-ray dose required for image acquisition can vary depending on the X-

ray source and environmental circumstances. You must maintain the

exposure time and change the kVp and mA values according to the signal

level. In addition, if the X-ray source and the distance to the sensor were

changed during the initial installation, the distance (from cone to detector)

must be changed to the 80mm setting.

To reduce an initial measuring error, you should use a 4mm Al filter to

maintain a distance that is identical to the conditional circumstances of the

test.

The exposure time may vary depending on the age, gender and bone

density of the patient.

Appendix

How to optimize the exposure conditions?

Position the EzSensor and the X-ray source, as shown below. The distance between the cone and the

detector should be 80mm (8cm). Please align the X-ray source over the sensor.

1. Distance: 80mm(8cm) (from cone to detector)

2. Added filter: 4mm Al filter (or No filter )

3. Signal level: after calibration of image

Run program ‘_EzSensor150’ located in C:\EzSensor150

Appendix

Follow the steps below:

[Step 1] Click the ‘Calibration’ tab.

[Step 2] Click the ‘Get Bright’ button for the exposure time.

; Refer to ‘Table 4. Detailed Exposure Guidance Table’.

[Step 3] Check the command window.
