Performing 5-Point Bright Calibration
Follow the procedure below to perform CEPH sensor bright calibration.
5) Run the C:\VCaptureSW\Acquisition\CEPH \WideCEPH \Norm(Fast)\VACAP.exe file.
6) Send Normal :[SPM_FREQ_0160], Fast : [SPM_FREQ_0313] to the command window to set
the CEPH sensor and the collimator. If you wish to acquire Normal(Fast) Cal, please send each
command by sequence as in the table below:
Commands Description
[SPM_CEPH] CEPH mode
[SPM_HSON] CEPH sensor power on
[SPM_FREQ_0160]
[SPM_FREQ_0310]
HR mode: sensor frequency setting
GR mode: sensor frequency setting
[SPM_FOVO] Colimator open
[SPM_COLM_0005] AL filter open
For fast folder, enter [SPM_FREQ_0313] Instead of [SPM_FREQ_0160].
Acquisition Conditions 5 Point
exposure condition
kVp0 680
mA0 650
kVp1 900
mA1 1400
7) When the final value does not fall into the range on the table in 1.3 CEPH Sensor Bright
Calibration, please do the following:
 When CALPoint 1 is below 50 or above 80: adjust the value of kVp0 by 10 points
until the final value falls within the range between 50 and 80.
 When CALpoint 5 is below 400: adjust the value of kVp1 by 10 points until the final
value reaches 400 or above.
8) Click the “Bright” button, when you see that CALpoint 5 satisfied the standard (400 ~) to obtain
the 5-points bright Calibration data.
9) Bright cal data is stored in C:\VCaptureSW\Acquisition\CEPH \WideCEPH \Norm(Fast)\CAL
file.
10) When the normal bright cal acquisition is completed, click the check button to create an auto
bad pixel map.
