### Registration Devices

#### RGDV 1...8 Data Set A

Room: Room 1...3 for room door contact and radiation warning lamp wiring
seedoc INSTALLATION, WG unit required if more than 1 room

to switch over - room door contacts (where available)

- radiation warning lamps

indication for PDO (patient data organizer) option prints

Tube: None RGDV not available, ‘None’ can be used to disable a RGDV selection
without erasing the tube data in mA_control and RGDV setting in CU

Tube 1...3 a tube must be programmed to enable the RGDV selection

#### Release circuit number: Circuit 1 ... 4

- one out of four release circuits of a 'Release circuit adaptation unit' 1WA, 2WA, 1WB, (2WB not yet available)
  (e.g. Adapter for 4 aux. units WA: 1 = EWAX1 2 = EWAX2 3 = EWAX3 4 = EWAX4)
- ignore in case of a 'Bucky Ctrl. 1/Dig. Diag.' or 'Thoravision'
- ignore, if 'none' is programmed for a 'Release circuit adaptation unit' (e.g. free cassette RGDV without cassette present interlock)

RGDV number and 'Release circuit number' do not have to be the same, if required all 8 RGDV's can be programmed to one release circuit only.

#### Enable handswitch at generator desk:

yes = release with the desk hand-switch and via release decade of WA or WB possible
'yes' must be programmed for systems assigned to
'Mounted radiographical controller's ‘Bucky Ctrl. 1/Dig. Diag’ or ‘Thoravision’

no = release via the programmed decade of WA or WB only ('Release circuit number')
'no' must not be programmed in combination with ‘Bucky Ctrl. 1/Dig. Diag.’ or ‘Thoravision’

#### Syncmaster present (e.g. grid contact):

yes = has to be programmed in case of

· ‘Release circuit adaptation unit’s (WA/WB):

· grid synchronization (20-21) decades X1...X4 pins 1-2

· ditto tomo release (exposure request of layer angle), dec. X1...X4 pins 1-2

· if cassette present interlock (free cassette) does not use a ready circuit but this sync contact,
decades X1...X4 pins 1-2

· BuckyTH, BuckyTH2, Bucky unit of easyD,
Digital Diagnost systems via CAN for grid sync,
tomo release synchronization and free cassette,
release via signalbus EZX23 CTRL_X/ (FCO: BuckyTH 00 231 007,
easyD 00 263 009)

· Thoravision RGDV1 (drum) via signalbus EZX23 CTRL_X/

no = in case of free cassette RGDV's,

· no release decade required
then no link has to be inserted to any of the 4 release decades pins 1-2 (20-21) of the adaptation units WA/WB,
the free decade can be used for another auxilary

· must not be programmed for BuckyTH, BuckyTH2, Bucky unit of easyD,
Digital Diagnost and Thoravision systems via CAN

· must be no for adaptation at BuckyTH2, Bucky unit at easyDiagnost with BuCo firmware >= 5.x,
Digital Diagnost, complete setting see 'Adaptation'

#### Exposure switch type:

double step = individual PREPARATION and EXPOSURE request with the desk hand-switch or via the release decades of WA/WB

· must be programmed if ‘Exposure series / Tomo movement’ = ‘yes’

· must be programmed for BuckyTH, BuckyTH2, Bucky unit of easyD, Thoravision and Digital Diagnost systems via CAN

single step = instant EXPOSURE request with PREPARATION only, released from

· the desk hand-switch or

· a release decade at WA/WB or

· the PREP switch S2 of a 'Release circuit adaptation unit' WA/WB

Does not work without 'Release circuit adaptation unit' WA/WB.

· must not be programmed if ‘Exposure series / Tomo movement’ = ‘yes’

· must not be programmed for BuckyTH, BuckyTH2, Bucky unit of easyD, Thoravision and Digital Diagnost systems via CAN

If 'intermediate boost' mode has been 'enable'd to activate double boost mode, it will automatically be off if 'single step' is programmed.

#### Bucky format density correction (6% steps)

range = - 8 ... + 8 steps see Steps

· input at WAX11/12 pins 1-2 or WBX11 pins 1-2,
side-fields active when contact closed (>24x24cm), center field only when open

· density correction during collimation with GALILEO collimator Bucky TH, TH2, Thoravision or Digital Diagnost

Cone density correction (6% steps)

range = - 8 ... + 8 steps see Steps

· correction when cone in use, input at WB X13 pins 4-5, active when closed, Optimus R/F only

#### Dose measurement input

none = no AEC / AECF / TDC function available.

EZX61 in use for dose rate inputs, in this case the exposure on signal X_ACT/ has to be connected to the central part via signal bus

EZX21 | = | chamber 1 | \ |  |  |  |  | to be used for Amplimat and/or R/F photo sensor input (R/F (e.g.DSI) EZX41 preferred) |
EZX22 | = | chamber 2 |  | \ |  |  |  |
EZX31 | = | chamber 3 |  |  | ---- | backpanel input plugs |
EZX32 | = | chamber 4 |  | / |  |  |  |
EZX41 | = | chamber 5 | / |  |  |  |  |
| AEC | = | A utomatic Exposure Control (option) | = | Amplimat (DSI) falling load
| AECF | = | AEC Fixed current (if AEC option present) | = | Amplimat (DSI) kV - mA
| TDC | = | T omo Density Control (option) | = | Amplimat (DSI) kV - mA controlled

#### Dose measurement sensor type

Bucky amplimat input via EZX21 / 22 / 31 / 32 / 41
measuring field selectionon control desk possible

Scopo amplimat input via EZX21 / 22 / 31 / 32 / 41
only center field displayed at the control desk

‘Scopo amplimat’ must be programmed in case of a Junior Diagnost or Extremities measuring chamber to prevent the side-field selection and display.

Photo sensor input via EZX61, if ‘none’ has been programmed at ‘Dose measurement input’, the exposure on signal X_ACT/ to the central part has to be connected via signal bus EZX23

Photo sensor/ampl. inp. photo sensor input only via EZX41 to get the REL signal (as EXON signal) for AEC and all free techniques, e.g. kV-mAs

#### Exposure series / Tomo movement

no = instant brake after exposure end
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

yes = more than one exposure possible with one PREP
- no underexposure display in exposure series / tomo if ‘no’ is programmed at ‘RGDVx Data Set B’
‘Underexposure display (non automatic techniques)’
- has to be 'yes' for
- any tomo in combination with a 'Release decade adaptation unit' 1WA/2WA
(reason: preparation must be active until the tomo stand is back to the start position = „dead-man’s“ principle)
- DSI or multiple exposures with SCOPO

# Note

(makes no sense if ‘single step’ ‘Exposure switch type’ selected)

### Release delay (automatic techniques)

enable Must be set for AEC / AECF / TDC / PHOTO TIMER techniques to switch on kV not before the dose integrator has been reset and the offset of the chamber signal line has been measured by Dose Rate Control.
Must also be enabled for mobile Amplimat stands without grid sync connected.
- Automatically ‘disable’d if any non-AEC technique is selected.

disable Instant start of kV with EXPOSURE command, should never be programmed.
Must not be programmed using AEC, AECF, TDC technique.

RGDV 1...4 Digital Diagnost via system CAN
RGDV 5...8 Bucky unit at easyDiagnost via system CAN

Bucky Controller 2 = not used, ignore

Thoravision = RGDV 1 only at Thoravision,
interface EWD200 via system CAN

# Note

If an exposure end beeper is required in the examination room (even for free cassette) the RGDV must be assigned to the ‘Release circuit adaptation unit’ to activate the EXON optocoupler at WA X13/14. R/F systems provide the beeper driven from WBX13.

### Mounted tomo extension

only, if at least one 'Release circuit adaptation unit' 1WA and/or 2WA option is present

none = no tomo auxilary

!! none !! must be selected if any 'Mounted radiographical controller' is programmed
