7. Functional Description
The system is supplied with power via the
power unit transformer (2) (green LED (12)
lights). The 2.5 m long cable from the CCD-
Sensor (11) is now connected to the CCU
control unit (1). The CCU Controller is
connected to the USB-Converter (3) using the
transmission cable (6). The USB-Converter is,
in turn, connected by the USB adapter cable
(4) to a free USB-port on the PC (5).
The CCD-Sensor is equipped with a
disposable protective cover and placed in the
mouth of the patient. Finally, VistaRay must be
activated via the X-ray software so that it is
ready for imaging. This is shown by the yellow
LED (13).
6. Functional Diagram
During X-ray imaging, the X-rays are
converted into light rays by the presence of
the scintillator (light substance) which is
present on the CCD-Sensor. After recognition
by the CCD-Sensor that exposure has taken
place, these are then recorded as an image.
The image data is then digitalized, stored to
memory in the CCU Controller and finally
transmitted to the PC. If an error in block
sequencing occurs during transmission then
the image information can be sent again.
During data transmission it is not possible to
carry out further imaging.
