MATLAB: Hi,how to change the resolution of DICOM image

dicom image-medical image processingImage Processing Toolbox

i have a series of dicom image that has a 512*512 matrix.i want to decrease the resolution of this image to the 128*128 matrix.

thanks in advance to your answers and help me

Try imresize():

image128 = imresize(image512, [128, 128]);

I don't know a lot about DICOM images, but a possibility is to use

 dicomread
 imresize
 dicomwrite

in that order.

Try imshowpair() or imfuse(). If they're not in your 3 year old version then upgrade to the newest version or else stitch them together with , or ;.

wideImage = [image1,image2];
tallImage = [image1;image2];
