I am IT student and new to the medical field. I am currently working on Image Processing/Classification Tasks and working with Slicer. I still think I have some understanding issues regarding the Coordinate System used and was hoping you guys could maybe help me.
I currently have data in .nrrd files I work with. From the Header Information I can extract:
‘space’: ‘left-posterior-superior’ → So I can assume my Data is in LPS
[ 5.98936111e-01, 6.15821439e-05, -5.15675320e-03]
[-1.20481869e-08, 5.98915625e-01, 7.15087395e-03]
[ 4.13286886e-02, -5.73043156e-02, 4.79947636e+00]
[-115.52378082, -56.22384262, -92.38769531]
So I assume my data is using this system? As Slicer uses RAS it transforms this data from LPS to RAS when viewing it in Slicer?
I would like to rescale all my images to 1 in x, y direction to make them more comparable.
To do that I just have to apply a corresponding transformation matrix to my data if my understanding is correct?
Overall I am still confused as to what corresponds to what data in which coordinate system.
