Hi all I am working with multidimensional array of CT images in mat format. Now I need to save them as *.dicom files. By using dicomwrite, the intensity (pixel) values fall within smallest value=0 to max= 65535(default). Thus all my finer details of my image is lost (image is almost blank & most of the part is white). I want to retain the same details after conversion to dcm files. Could anyone please help me with this.
Thanks

How do you normally display the image? Are you using imagesc() With some particular colormap ?

when it is in mat file, I use imagesc() with colormap gray. when it is dcm file, I use imshow().

mindata = min(YourData(:));
maxdata = max(Yourdata(:));
mappeddata = uint16( (YourData - mindata) ./ (maxdata - mindata) * 65535 );
Now write mappeddata
