Hi , I have a mat file including 320 slices of CT image and I am trying to convert them to dicom file using the codes below:
load Reconimg.mat;
size(img) % e.g. if size dimensions = 125x125x320
for image_num = 1:320
dicomwrite(img(1:512,1:512,image_num));
sprintf('Reconimg%s.dcm',num2str(image_num));
end
but I get the following error
Error using dicomwrite (line 178)
At least two input arguments required.
could u please advise
Thanks

for image_num = 1:320
dicomwrite(img(1:512,1:512,image_num),FILENAME);
sprintf('Reconimg%s.dcm',num2str(image_num));
end
you forgot to put the filename argument.
use
help dicomwrite
for more information

sorry I didn't write it well it's
filename=strcat('reconimg',num2str(image_num),'.dcm');
dicomwrite(img(1:512,1:512,image_num),filename);
the whole code should be
for image_num = 1:320
filename=strcat('reconimg',num2str(image_num),'.dcm');
dicomwrite(img(1:512,1:512,image_num),filename);
sprintf('Reconimg%s.dcm',num2str(image_num)); %you can delete this if you want
end

Thanks , so turned out the mat file should be the int16 in order for the dicomwrite to work , so here is how it works:
for image_num = 1:320 filename=strcat('Reconimg',num2str(image_num),'.dcm'); B=int16(Reconimg(:,:,image_num)); %dicomwrite(Reconimg(1:512,1:512,image_num),filename); dicomwrite(B,filename); sprintf('Reconimg%s.dcm',num2str(image_num)); %you can delete this if you want end

Hi Hany, where do you define the variable Reconimg? Because I am having trouble with these sentence: B=int16(Reconimg(:,:,image_num)); Undefined function or variable 'Reconimg'.
