Positioning the Imaging Sensor
To ensure image quality, the digital imaging sensor must be positioned properly (for
information about the proper placement of the imaging sensor, please refer to
'Positioning Instructions' on page 19.
Failure to position the imaging sensor properly can result in errors on the
radiograph, such as distorted teeth and roots, elongation, magnification, and
overlapping contacts.
Failure to align the imaging sensor with the exit pattern of the X-ray beam can
result in cone-cuts on the radiograph. The cone-cuts are clear areas that are
shown on the radiograph when part of the radiograph is not exposed to radiation.
Please refer to the following figure as an example of cone-cuts.
The following figure indicates how the cone-cut occurred by showing the position of the
imaging sensor and the radiation area.

The paralleling technique generally reduces the risk of such errors, but
if you position the sensor improperly, angulation errors may occur
(angulation of the sensor to the tooth itself).
