QA BEAMCHECKER™ PLUS 63
14 Appendix C: Explanation of Saved File Export
When exporting data or deleting a room from the QA BeamChecker Plus Communication
Software database, a .csv file, (comma separated value) file is created that can be directly
opened with any spreadsheet application. Each mode has a different exported format, and the
resulting files will have data labels as described below.
14.1 Static 5 Channel Mode
When exporting from the Static 5 Channel Mode, an individual file is created for each energy.
The format of each file is broken down into multiple sections using the following pattern:
Baseline1; Measurements for Baseline1; Baseline2; Measurements for Baseline2; etc
Baseline Data
A unique identifier for the baseline energy that incorporates date and
time of measurement
Collimator size, as entered in the Baseline Setup screen
Source to Surface Distance, as entered in the Baseline Setup screen
Linear accelerator dose rate, as entered in the Baseline Setup screen
Linear accelerator dose, as entered in the Baseline Setup screen
Gantry angle, as entered in the Baseline Setup screen
Internal temperature when baseline measurement was taken, in °C
Pressure when baseline measurement was taken, in mmHg
A unique identifier for the baseline energy as determined by several
ionization chambers and a proprietary algorithm
Axial symmetry of baseline energy, calculated from the ionization
chamber readings
Transverse symmetry of baseline energy, calculated from the
ionization chamber readings
Flatness of baseline energy, calculated from the ionization chamber
readings
Data collected from the center ionization chamber during the
baseline measurement
Data collected from the left (photon side) or right (electron side)
ionization chamber during the baseline measurement
Data collected from the top ionization chamber during the baseline
measurement
Data collected from the right (photon side) or left (electron side)
ionization chamber during the baseline measurement
