Users Guide V8.0:Radiotherapy Exercises
This section proposes some exercises ( with the GATE software allowing for radiotherapy and dosimetry simulations. Simulations are organized in a folder, with the following subfolders : data, mac and output. Macros files are stored in mac. Gate must be run in the initial simulation folder, such as : Gate mac/main.mac (don't forget the mac/). The macros that make use of data must refer to the data/ subfolder. The general idea it to try to understand every commands in the macro files to be able to analyze the results.
Simulations macros may be found in this.
Examples located in the GATE examples directory
These examples are located in the folder : Gate/examples/example_Radiotherapy/.
Example 4 : Beam optics simulation in vacuum for a pencil beam + depth-dose profile in water. A root macro is provided to analysis the produced phase space files (PhS-Analysis.C).
Example 5 : Treatment plan simulation of proton active scanning beam delivery (TPSPencilBeam source). A root macro is provided to analysis the produced phase space files (PhS-Analysis.C).
Example 6 : Example of proton pencil beam in heterogeneous phantom (water, bones, Lung) with Pencil Beam Scanning source: comparison between dose to water and dose to dose to medium.
Carbon ion therapy
Example 1 : Example of Carbon beam in water tank or in patient CT image. Output is a 3D dose distribution map (with associated statistical uncertainty) and map of produced C11.
Example 2 : Example of photon beam in patient CT image. Output is a 3D dose distribution map (with associated uncertainty). Two different navigators are tested NestedParameterized and Regionalized, with two number of materials).
Example 3 : Example of photon beam in patient CT image with IMRT irradiation. 100 slices with different MLC positions.
Example 7 : Example to use repeater/mover and both at the same time.
Example 8 : Photon beam from a Linac into a box with water/alu/lung. See Figure4 from [Jan et al PMB 2011].
Example 9 : Electron beam from a Linac into a box with water/alu/lung. See Figure5 from [Jan et al PMB 2011].
Example 10 : Radiography of a thorax phantom. Outputs are 3D dose distribution maps computed with the classical method and the accelerated (TLE) method.
