Active CCD Sensor
The intraoral sensor consists of a large-area silicon chip (CCD/CMOS) with an X-Ray transducer screen placed in small,
ruggedized enclosure.

Sensor Formats:
Sensors are available in the same sizes as film: #0, #1, #2. The image area is specified below:

Sensor Package Form Factor:
a. The approximate sensor thickness is only 3.2 mm, the thinnest available.
b. The packaged sensor head has a maximum active area. This allows easy and comfortable placement of sensors in
the mouth.

Sensor Encapsulation:
The sensor is encapsulated into a two component, form-fitting metal enclosure that is sealed together to comprise a
durable encapsulation.

Sensor Cable:
The intraoral cable is UL-rated flexible polyurethane with a 9 foot (3 m) length with 0.140" diameter.

Usable Intraoral X-ray Sources:
The sensor can be used with ordinary intraoral X-Ray sources with a maximum rating of 70 kV.

X-Ray Imaging Properties:

1. Resolution: The pixel resolution of the high resolution (HiRes) sensors exceeds 22 lp/mm. The standard resolution
of an X-Ray image, as measured by the modulation transfer function (MTF) exceeds 12 lp/mm. This is measured by
using a standard 60 kV intraoral X-ray source.

2. Dose Efficiency: The sensor will produce a high quality image with an X-Ray dose that is only a fraction of the
standard dose required by Dental X-Ray film.

3. Diagnostic Efficacy: The system will produce a superior image quality of images obtained when using standard
dental X-Ray film. This allows the dentist to diagnose standard intraoral pathologies encountered during screening
procedures.

4. Wide dynamic range: The sensor pixel well capacity is very high, allowing a higher accommodation of greyscale
(bone density) dynamic range.

Disinfection Properties:
The sensor can easily be chemically disinfected. The sensor may be disinfected by wiping with CidexT.

Sensor Material Biocompatibility Specifications:
The sensor's body material and cable material are biocompatible. The sensors and all component materials have been
tested to comply with ISO standards, and specifically, the sensor complies with EN30993-1 (Biological Testing of Dental
and Medical Devices).

Sensor Storage Requirements:
The sensor must be stored and operated in at a temperature range between 10ºC and 40ºC.
