image - Transforming raw pixel using rescale slope and rescale intercept in DIcom -
i used solution in post window width , center calculation of dicom image transform raw pixel, works of images, faced problem images. images having pixel value "24", rescale slope "1.0" , rescale intercept "-1024". when applied solution mentioned above new pixel value in negative(-1000).
i can't find value new pixel value in lookup table created using window level , window width because table having positive values (0 65536). please me solve problem.
you dealing ct images. rescaleintercept tag cts set -1024. negative -1000 value obtain makes perfect sense, corresponds air in hounsfield units (as anders said). if want visualize image, have apply transfer function map hu scale rgb instance.
