2.2. SYSTEM COMPONENTS
“x-mind ac” radiographic system (Fig. 1) consists of:
1. x-mind ac TIMER
The timer is the control panel used to manage the exposure times and to safely use the tubehead.
To make the exposure, the control button with safety key is available.
The timer can be connected to n° 2 ac tubeheads.
In case of alternate current tubeheads the technology of the timer is “self - compensating”:
depending on the line voltage uctuation, the microprocessor automatically modies the predetermined
exposure time ensuring a constant dose to the patient.
This technological expedient avoids the repetition of the exposure because of over/under exposure errors.
2. BRACKET
The horizontal bracket is available in 3 different lengths (110 cm, 80 cm, 40 cm) and represents the support for
the pantograph arm. Its shaft is xed in a dedicated section of the timer (top or bottom) and allows for 180°
movement.
3. PANTOGRAPH ARM
Thanks to the new shape and new mechanisms of the positioning arm, it can be adjusted in height and depth in
order to precisely explore any spot in its reach.
It is made of light alloy with an ABS coating.
4. x-mind ac TUBEHEAD
The intra-oral tubehead “x-mind ac” is a monoblock type and its light alloy housing contains an airtight
compartment.
The high voltage transformer, the X-ray tube and the expansion chamber are submerged in highly dielectric
insulating oil inside a light alloy container.
The expansion chamber guarantees an adequate compensation to oil expansion for the entire temperature
range.
The X-ray tube is located in the back part of the container, allowing a source-skin distance 50% higher than
traditional structures.
