Adjustment of the equipment specific dimensions
Program 24film-object-distance
The film-object-distance can be adjusted depending on the used Bucky from 5,0 cm until
10,0 cm. The basic set-up of 7,0 cm has to be amended during installation. Measure the
distance from the table top to the cassette tray. Then deduct 1,1 cm from the determined
measure because of position of film in cassette. Adjust the result figure on control panel
and save.
Program 25film-focus-distance
The desired vertical SID can be put in from range 100 cm until 115 cm respectively 38 inch
until 45 inch. After installation of tube and collimator (center of gravity) as well as Bucky the
SID-switch in the column has to be adjusted to this value and glue the included tomo bench
mark.
Basic set-up 115 cm (standard) respectively 40 inch (USA-version).
Program 26table top-rotation-distance
can be adjusted from 85,0 cm until 112,0 (rotation = rotation axis of supporting arm)
Adjustment: 106,0 cm standard respectively 92,6 cm (USA version) has to be measured
during installation corresponding to correct adjustment of SID and to be corrected.
Remark: The correct adjustment of the SID on the equipment and the exact input of
the values in Program 24 and 26 determines the exactness of the fulcrum height during tomo exposure!
Control system and tomography-exposure time
Program 23Exposure control
Choose between angle controlled (radiation release switched-off during tomo exposure
with the tomo control) and time controlled (radiation release switched-off with generator).
two exposure times of each Tomographic angle can be chosen in steps of 0,1 s within the
marked range:
8°0,4 s to 1,2 s
20°0,6 s to 3,0 s
30°1,0 s to 4,0 s
40°1,5 s to 4,0 s
Basic set-up (biggest and smallest time of each angle) has to be amended during installation to generator.
The adjusted values shall be recorded in the file „customers setting“ of the parameter
index (see enclosure). This index is included to the mounting instructions and supplied to the customer.
* The zero positions of the axis are adjusted so that:
- the tube stand is positioned to table center
- the zentralray of the tube is vertical
- the Bucky middle to the tube is centred
NOTE:
The indicated and saved analog valve on the control panel varies depending on the mechanical basic set-up. This will not influence the exact centring of the axis. It is decisive that
the mechanical axis position corresponds with the index of the incremental transmitter.
Attention!
If the zero positions (programme 4 and 5) will be amended more than 5mm afterwards for
example during installation, the software end positions (programme 7 to 10) have been
amended too.
