I have a liver CT dataset where all images is in .nii file format. Each image file has mulitple slices (say 512*512*500). Using niftiread command i read the image file and now I am visualizing each of the 500 slices one by one using imshow command.
Now my image 'i' is class int16 and has values from 0 to 2328. I think these values are Hounsfield units (HU). My image 'i' is like below, where i couldnt see any fine details from the image.
When i referred a paper they said as, 'the Hounsfield unit is applied in window range [100, 400] and then after some pre-processing steps the image is visualized.
how can i do that to bring my image 'i' like a normal CT image?
