14.2 TomoTherapy Mode - Static Plans
When exporting from the TomoTherapy Mode, an individual file is created for each plan. 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
Lateral profile of baseline, calculated from the ionization chamber
readings
Output measurement of baseline, calculated from the ionization
chamber readings
Baseline energy measurement, calculated from the ionization
chamber readings
