Hi,
i'm truying to get roi pixel values from many slices in the same folder,
dicomlist = dir(fullfile('D:\master\LUNGIX\LUNGIX\PET PETCT_WB_apc (Adult)\PET WB - 102\','*.dcm'))
for cnt = 1: size(dicomlist,1)
Slice(:,:,cnt) =double (dicomread(fullfile('D:\master\LUNGIX\LUNGIX\PET PETCT_WB_apc (Adult)\PET WB - 102\',dicomlist(cnt).name)));
for i=1:size(o,1)
roi(i)=double(I(a(i),b(i)));
res(:,:,cnt)=double (roi(i));
end
end
this gives the same pixel values for each slice
thanks in advance
