You will need the Image Processing Toolbox. Here is a reference: http://www.mathworks.nl/help/images/ref/dicomread.html
On this page there is an example:
info = dicominfo('CT-MONO2-16-ankle.dcm');
Y = dicomread(info);
figure, imshow(Y);
imcontrast;
Please note that the image you use can be yours.
I would do something like
a = dir('*.dcm')
for i=1:length(a)
info = dicominfo(a(i).name);
Y = dicomread(info);
figure, imshow(Y);
%%or do some other procesing.
imcontrast;
end
