hi all,
i have image dicom 16 bit. my problem is, 16 bit image can stored pixel value till 32767 only. now i want change it to 32 bit or 64 bit so that the pixel value can stored more than that, and corresponding how much activity radionuclides i used to diagnosed patient.
Anyone knows how to convert that using matlab? or anyway to solve it?

I use the following code for my DICOM dose files to be read by MIM Maestro:
MaxUnsignedInteger = 65535; % cf. https://en.wikipedia.org/wiki/65,535#In_computing
blurreddose = MaxUnsignedInteger / max(max(max(blurreddose))) * blurreddose;
blurreddose = uint16(reshape(blurreddose,...
                 [size(blurreddose,1) size(blurreddose,2) 1 size(blurreddose,3)]));
Have you read the documentation for uint16, uint32, uint64 ? These articles may answer or lead you to the answer you need.
