High Resolution Image Acquisition - Dentsply Sirona Schick 33 User Manual

5.2. High Resolution Image Acquisition

Schick 33 Sensors have a theoretical resolution (Nyquist Limiting
Frequency) of 33.3 lp/mm (33.3 line pairs per millimeter). The Sensor is
capable of acquiring images in either high resolution mode or standard
mode. High-resolution mode, which is unique to Schick 33 Sensors,
captures a level of detail measured at 28 lp/mm.
The above image shows a line pair measurement phantom captured with a size 2
Schick 33 Sensor. The phantom measures up to 28 lp/mm, which the Schick
Sensor is able to demonstrate in the enlarged section highlighted in red.
The increase in image information in high-resolution mode means also
that the transfer from acquisition-to-display time may be higher. On
newer PCs with multiple processors this difference is negligible. High-
resolution images are also physically larger in terms of their file sizes:
approximately 8 MB / image with a size 2 Sensor.
5.2.1. Selecting High Resolution Acquisition
Taking high-resolution images with Schick 33 Sensors is enabled by
default (High Resolution menu option selected). If High Resolution has been
de-selected and you wish to re-enable it, open X-ray acquisition
options and select High from the Resolution menu.
(In CDR DICOM, browse to the System menu, select X-ray Settings, click on the
Image tab, and select High from the Resolution drop-down menu. Click Apply,
and click OK to close the page for X-ray acquisition options.)
