I would like to know the use of Pixel Intensity Relationship & how it
is used in displaying the image
Thanks in advance

You say you develop your own viewer... Are you sure you are using
correctly the supplied image information? Mind that the stored bits per
pixel are 8, not 16 or 24.
I haven't done much Java (I'm a C/C++ guy) but I've experienced strange
image displays when missing the byte alignment on bitmaps, for instance
when using an array of shor ints to store 8 bit grayscale images and
then pass that array as a bitmap to the renderer.
Is it possible you have a similar problem?

May be the transfer syntax is the problem, you check if is little
endian or big endian, there in the UID is: 0002,0010,Transfer Syntax
UID=1.2.840.10008.1.2.1. and check the bits stored and bits asigned ?
