1. Introduction
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.

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.

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.
39
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
