The resultGUI struct

The optimization output is declared as resultGUI and contains at least two fields. The first field w contains the optimized weights and the second field specified as physicalDose holds the physical dose cube in ct dimensions N_x × N_y × N_z (N_{x, y and z} = number of voxels in x-, y- and z-direction). Each field in the resultGUI struct can be easily accessed via MATLAB's dot-operator. For instance, resultGUI.w outputs the fluence weight vector.

In case of performing a biological optimization using carbon ions, the resultGUI struct holds several additional cubes as fields:

• resultGUI.effect - represents the biological effect cube
• resultGUI.RBExDose - contains the biological effective dose = RBE x physical dose
• resultGUI.RBE - holds the relative biological effectiveness cube
• resultGUI.alpha - represents the radiosensitivity parameter α_Particle cube stemming from the linear quadratic model
• resultGUI.beta - represents the radiosensitivity parameter β_Particle cube stemming from the linear quadratic model

Executing matRadGUI in MATLAB's command window will start the GUI and will display all available data of resultGUI.
