QA BEAMCHECKER™ PLUS 64
BOTTOM_RAW
Data collected from the bottom ionization chamber during the
baseline measurement
ONE_MM_ALUM_RAW
Data collected from energy channel 1 during the baseline
measurement, primarily used for electrons
SIX_MM_ALUM_RAW
Data collected from energy channel 2 during the baseline
measurement, primarily used for electrons
SIX_MM_LEAD_RAW
Data collected from energy channel 3 during the baseline
measurement, primarily used for photons
NUM_SAMPLES
Number of samples collected by the analog-to-digital converter
during the baseline measurement
EXPECTED_OUTPUT
Expected Output, as entered in the Baseline Setup screen. This
number is shown in up to four digits, e.g. 100.0% shows as 1000
Measurement data
Data Label
Description
BASELINE_ID
Identifies which baseline energy values were chosen for comparison
to measurement data
DATE
Date when measurement was taken, in the format mmddyyyy
TIME
Time when measurement was taken, in the format hhmmss

CONSTANCY
Constancy of measured energy, calculated from the center ionization
chamber compared to baseline center ionization chamber value
TEMPERATURE
Internal temperature when measurement was taken, in °C
PRESSURE
Pressure when measurement was taken, in mmHg
ENERGYLEVEL
A unique identifier for the energy as determined by several ionization
chambers and a proprietary algorithm. This is then compared to the
set of ENERGYLEVEL values from baselines above
AXSYM
Axial symmetry of measured energy, calculated from ionization
chamber readings
AXSYM_%DELTA
Axial symmetry percentage difference from baseline
TRSYM
Transverse symmetry of measured energy, calculated from ionization
chamber readings
TRSYM_%DELTA
Transverse symmetry percentage difference from baseline
FLATNESS
Flatness of measured energy, calculated from ionization chamber
readings
FLATNESS_%DELTA
Flatness percentage difference from baseline
CENTER_RAW
Data collected from the center ionization chamber during
measurement
LTP_RTE_RAW
Data collected from the left (photon side) or right (electron side)
ionization chamber during measurement
TOP_RAW
Data collected from the top ionization chamber during measurement
