no = no tomo functions active
yes =- must be set if any 'Mounted tomo extension' is programmed at 'RGDV Data Set A' (tomo time input active only in combination with
option Automatic input of tomo times 9890 000 0222x)
- must be programmed in connection with a
Bucky TH, TH2, Digital Diagnost with TOMO, which gives access to the 16 tomo
times (11 only Digital Diagnost) in the System (tomo time input only in
combination with option Automatic input of tomo times 9890 000 0222x)
- if 'yes'
is set exposure time +/- corrections are not possible at the control desk
no = no fluoro possible
yes =- only possible in combination with ‘Release decade adaptation unit’ WB and if programmed in generator
function key EZ139 D38, generator base must be R/F
- if fluoro is set to ‘yes’ the menu/APR field at
the control desk line 1 column 2 is reserved to display fluoro parameters (kV,
mA, time) and cannot be used for menu or APR names anymore
for therapy simulator purpose, allows run times >= 16 seconds in continuous fluoroscopy mode, function not applicable
no = default, exposure time +/- selection
possible at the desk if no tomo RGDV
yes = disables
exposure time +/- corrections at the desk
if
a RDGV is 'Used for tomo' = yes the
time +/- corrections are automatically disabled

The density correction displayed at the desk only shows
e.g. All RGDV's (and all systems in the same hospital) should
have the same correction factor to get the same result when used. More
explanation in 'Change APR Data Set'. |

- For individual stand or other registration
device related corrections
No
correction should be programmed before the site specific film-screen combination densities in the ‘Dose Rate Control’
part have been adjusted. |
yes The
incorrect exposure indicator is blinking at the control desk to indicate that
an exposure has not been terminated by the generator (FU_mA controls all non-AEC techniques kV-mAs, kV-mA-ms,
kV-mAs-ms),
e.g. if
- the hand-switch has been released prior
to the set exposure time
- the sweep time switched by the tomo
table is shorter than the programmed exposure time
- the exposure switch is bouncing.
Preferred
setting for CAN connected tomo systems BuckyTH, TH2, Digital Diagnost, Bucky
units attached to Easy Diagnost systems to get the underexposure display on in case
of system problems or if customers let go the exposure position of the
handswitch too early
no ‘no’
must be programmed for all non-CAN
controlled tomo systems:
Times switched by a tomo stand might be shorter than the programmed APRT time,
ready disappears and the stand will stop.
