I use the dicomread to read a series of files and create a 3D matrix in Matlab. Then, I display the image in the coronal and sagittal directions. However it shows that there are some unknow stripes in the image:

I am sure that the data is correct because I can use other dicom viewers downloaded from the internet and there is no Stripes in the dicom viewers made from others. And here is the code which I use to read the files: PET.dir=get(handles.PET_Input,'string'); files=dir(fullfile(PET.dir,'*.dcm')); PET.fileNames={files.name}; PET.info=dicominfo(fullfile(PET.dir,PET.fileNames{1})); PET.voxel_size=[PET.info.PixelSpacing; PET.info.SliceThickness]';

        numImages=length(PET.fileNames); 
        hWaitBar=waitbar(0,'Reading PET DICOM files');
        PET.Matrix=zeros(PET.info.Rows, PET.info.Columns, numImages);
        for ii=1:length(PET.fileNames)
            fname=fullfile(PET.dir,PET.fileNames{ii});
            PET.Matrix(:,:,ii)=(dicomread(fname)); 
            waitbar((length(PET.fileNames)-ii+1)/length(PET.fileNames))
        end
        delete(hWaitBar);

It is more clearly from this figure!!! Is it possible that in the dicom file there is an parameter to normalize each slice? Besides, when I load some other files in other folders, I find that some have that stripes while others do not!!!!!!
