Thank you Daniel for your explanation.
Sure I’m aware of the normalization field embodied in FLAIR, however the normalization factor differs for both 1D and 2D projections.
Generally, the reason I use a MATLAB is that I’m scoring other quantities such as dose weighted LET and RBE using USRBIN thus I need matlab code that loads and converts the 2D projection plot.dat in to 2D array to visualize the spatial distribution of both dose averaged LET and RBE. The purpose is examine some clinical dose prescriptions and their relative effectiveness.
What I usually do and please correct me if I do it wrongly,
ZX_voxel dose = the third column converted to 2D matrix.
from there I normalize the dose by scale the number of proton time conversion factor:
Dose = ZX_voxel dose * 2.9e10 proton * 1.6021766208e-7
Also using the same conversion factor, when I plot the dose as a function in depth along central axis in matlab is not the same as 1D projection in flair.
Thank you.
Abdul.
