[ITK] An important question about intensity rescale of dicom images

[penitentepid epid]

Hi, ITK group

I have bunch of 12 bits dicom images whose intensity ranges from 0 to 4095.
(found in dicom header, bitsStoed =12, highBits = 11, pixel representation
= 0)
when i used image reader <unsigned short,2>, i got a image whose pixel
intensity are ranging from 0 to 65535. why does this happen? i mean i
understand unsigned short is in this range, but did itk internally rescale
image intensity somehow?

why not put highest of pixel intensity as it suppose to be (4095 in this
case), and leave rest bits to be zeroes..
