Symptoms

Bucky unit misalignment in vertical position radiation

Cross-hairs migrate more than ±1.5 mm from vertical line of bucky unit when ceiling suspension is moved 1 m longitudinally

Ranked causes

1. Ceiling suspension position incorrect (common)
2. Column not rectangular to beam axis (common)

First check

Measure cross-hair migration from vertical line

Test point: bucky unit front plate
Expected: +/-1.5mm, +/-1.5mm
Tools: mirror, field illuminator

Calibration: Delay time check by test exposures radiation

Adjustment of exposure delay time for anti-scatter grid motion after exposure release. Two test exposures made on film to measure grid position shift.

Ranked causes

1. Exposure delay time requires calibration (unknown)
2. Delay time adjustment needed (unknown)

First check

Lay lead plate 1 on anti-scatter grid 2

Test point: Grid surface
Expected: Lead plate secured with adhesive tape

Height sensor not functioning or incorrect current range

Height sensing function for ceiling suspension bucky tracking not operating; current value outside 5-18 mA range or unable to be read

Ranked causes

1. Zero current reading (I = 0 mA) (common)
2. Maximum current reading (I = 20 mA) (occasional)

First check

Measure current at VN1 height unit output

Test point: SZ1 X5 connector
Expected: 5 mA to 18 mA depending on table position, +5 to +13 mA (range)
Tools: Digital multimeter, service PC with VT100 monitoring

System programming required after installation

Generator and bucky controller configuration must be set up via PC connection using XRG-Scope software before system operation

Ranked causes

1. Initial system configuration not programmed (common)
2. Bucky controller configuration not programmed (occasional)

First check

Verify PC connection to generator

Test point: EZ139 X5 front side of generator
Expected: PC connected via COM 1 port

Anti-scatter grid replacement radiation

Worn or damaged anti-scatter grid requires removal and installation of replacement unit

Ranked causes

1. Anti-scatter grid wear or damage (unknown)

First check

Open top cover

Test point: cover button
Expected: cover opens

Bucky unit floor distance mismatch in 90° position patient safety

Bucky unit 1 not adjusted to same floor distance as bucky unit in table 2 when in 90° position

Ranked causes

1. Floor distance adjustment screws not set correctly (common)

First check

Tilt bucky unit to 90° position

Test point: bucky unit 1
Expected: positioned at 90° angle

Calibration: Exposure delay time radiation

Verify anti-scatter grid motion timing relative to X-ray exposure using test film measurements

Ranked causes

1. Exposure delay time requires verification or adjustment (common)

First check

Measure grid displacement on test film

Test point: Anti-scatter grid position marker on exposed film
Expected: Distance between spot and bar: 8–10 mm, 8–10 mm
Tools: Ruler or caliper, X-ray film

Change handedness from left-hand to right-hand version

Modify bucky DIAGNOST VE2/VT2 from left-hand to right-hand configuration.

Ranked causes

1. Handedness configuration change (unknown)

Compatibility requirements not met

System requires specific MS DOS version and XRG-Scope release for programming

Ranked causes

1. Incompatible DOS or XRG-Scope version installed (rare)

First check

Confirm DOS version on programming PC

Test point: DOS command prompt version check
Expected: MS DOS 3.3

Reposition bucky from longitudinal to transverse orientation caution

Change the ceiling suspension catches to switch the bucky DIAGNOST VE2/VT2 from longitudinal sensing to transverse sensing configuration.

Ranked causes

1. Configuration change required (unknown)

First check

Inspect catch connections

Test point: Catch 1 at UZ X8 and Catch 2 at UB AX1
Expected: Catches disconnected and ready for swap
