Special remark for Optimus C with DuoDiagnost systems:

·         Only 2 chambers

 

chamber 1 = EZX21 = Bucky
and
chamber 2 = EZX22 = wallstand

                    are available for DuoD.

 

·         Only 5 film-screen combinations can be controlled by Cockpit.
Data sets of film-screen combinations should be programmed at both chambers.
To be available at chamber 2 the data set  must be programmed at chamber 1 even if it might be used for wallbucky only.

·         Dose settings must be adjusted for each data set at both chambers.

 

<CANCEL>       or use  <ESC>

 

Only two values of the 'Data Set's of the 'Chamber's should be changed:

'Abbreviation' and 'Dose of FSC'.

All others must not be changed (e.g. all kV dependent characteristics).

 

If digital cassettes / imaging plates (PCR/FCR/KCR) type the desired sensitivity

(e.g. PCR200) in the 'Abbreviation'  field. Digital Diagnost and Thoravision

provide special speed Sxxx or DOSE names.

 

The value 'Dose of FSC [µGy]:' = Ks must be calculated:

 

     example 

 

Abbreviation:

 

The name of the film screen combination can be changed into every 6 digit string.

An FSC can be erased by filling the name field with blanks,

but: !!

There should never be a gap in-between the FSC data sets of a chamber. If

only one FSC is used, it must be at data set 1, the second must be on 2 etc. If

e.g. 4 data sets are active and the 1st will be erased by blanks (spaces), all

FSC's disappear  and AEC is no more available for this RGDV.

If any FSC will be removed from the last position all APR linked to this FSC have

to be programmed to any other still existing FSC, otherwise no FSC will be

displayed at the desk. When these APR are changed to another FSC the

background mAs values have to be adapted to the FSC sensitivity.

 

Since Release 3 predefined APR data sets can be programmed with the FSC

name = 'Abbreviation'. If the abbreviation string and the name in the APR data

set are identical, the FSC will be associated to the APR data set.

If no name is given in the default APR data sets, APR will be assigned to the

FSC which has the closest 'Dose of FSC[µGy]:'  value to the Recommended

Dose in the default APR data sets. The value can only be seen with the help of

APRMANager if the APR data screen is open or with the print preview.

 

Dose Request Chamber [µGy/V]:                     range: 0.50...32 µGy/V

 

Sensitivity of the selected measuring chamber.

Value must not be changed !

 

Dose of FSC [µGy]:                  range: 0.45...100 µGy

 

The initial value 'Dose of FSC [µGy]:' of the ‘DRC Handling / Start Automatic

DRC Processing’ (calculated by XRGSCOPE in the service PC) is set to achieve

a density of  1.0.

It can be changed according to the customers density "taste",  e.g. 1.5:

 

 

If default APR of the installation disk are selected with AEC technique the

exposure data at the desk will display the abbreviation of the FSC and a default

zero with a triangle for the density. This zero should be the basic value for the

desired density. It will not change whatever value for the ‘[Dose of FSC]’  is

programmed.
