topasgraphsim 27.0.1

GUI to analyze the results of a Monte-Carlo radiation simulation

TopasGraphSim

A GUI to simplify and streamline the plotting and analysis of medical physics simulations

This GUI can visualize and analyze percentage depth dose (pdd) and dose profiles (dp) simulations from TOPAS. Depth dose measurements are assumed to be in the z-direction, dose profiles in the x- or y-directions. Data read-in is handled by topas2numpy.

Installation

Install using pip:

$ pip install topasgraphsim     

Then, start the GUI by running:

$ python -m topasgraphsim

Or, if your Python is added to $PATH, simply run:

$ topasgraphsim

Open compatible files from the command line:

$ topasgraphsim "path_to_your_file"

Since all my testing in done on Windows 11, I cannot guarantee ToapsGrapSim will work on any other plattform. I'm open to suggestions or PRs making the software work better cross-plattfrom!

Parameters

Depending on the imported measurement, the following parameters can be calculated:

Measurement type	Parameters
Depth dose	Q-Factor	zmax
Dose profile	FWHM	CAXdev	FLATKrieger	FLATstddev	Penumbra (L&R)	Integral (L&R)

• Q-Factor : Radiation Quality Factor

• z_max : Depth at Maximum

• FWHM : Full-Width at Half-Maximum

• CAX_dev : Centre Axis Deviation

• FLAT_Krieger : Flatness of Dose Plateau (Definition by Krieger)

• FLAT_stddev : Flatness of Dose Plateau (Standard Deviation)

• Penumbra (L&R) : Width of Left and Right Penumbra

• Integral (L&R) : Integral below Left and Right Penumbra

Dependencies

The UI is based on the customtkinter library.

Requires python3, numpy, scipy, matplotlib, Pillow, python-opencv, pynput, requests, topas2numpy, and python-tkdnd.
