relative_dose_1d#

Python package to read 1-dimensional dose profile from a text file to perform subtraction and gamma analysis.

image_gui

Features#

For gamma analysis#

  • Interpolation between points

  • Profile positions does not require to be equal

Note

  • The gamma analysis algorithm is limited to absolute normalization relative to the maximum dose.

For data import#

  • PTW (R) and Varian (R) data formats suported.

Format specifications#

Data should be in M ​​rows by 2 columns, corresponding to positions and dose values, respectively.

The package has been tested with the following examples:

  • File in w2CAD format (used by the TPS Eclipse 16.1, Varian(R) company).

    In the algorithm, the start of the data is identified by the words: ‘STOM’ or ‘STOD’ Physical unit assumed to be in mm.

  • File in mcc format (Verisoft 7.1.0.199 software, from PTW(R) company).

    In the algorithm, the beginning of the data is identified by the word: ‘BEGIN_DATA’ Physical unit assumed to be in mm.

  • File in txt format. The data must be distributed in M ​​rows by 2 columns and separated for a blank space. The script ask for a word to identify the beginning of the data in the text file, a number to add to the positions, and a factor for distance dimension conversion.
