'horzcat' error when using dicomread() within a for-loop

1 visualizzazione (ultimi 30 giorni)
Hi
I have a set of 460 DICOM files that I would like to read in one-by-one, subtract 1000 from each pixel, and write them out as DICOM files. I have tried the following code, but continue to get an errror saying "CAT arguments dimensions are not consistent":
I=zeros(512,512);
for i=0:459
I=dicomread(['IMG (' int2str(i) ').dcm']);
I=im2double(I);
I=I-(1000*ones(size(I)));
I=int16(I);
dicomwrite([I,'IMG (' int2str(i) '.dcm'])
end;
I assume this problem comes from a line in dicomwrite(), but I can't work out how to change this.
Any suggestions would be much appreciated.
Thanks,
Roman

In the call to dicomwrite you have tried to concatenate the matrix of pixel data (I) with the name of the file - basically, you put the "I," in the wrong place. Also, I noticed that you've removed a ")" in the output filename that you probably meant to keep? Try this to write back to the same file:
dicomwrite(I, ['IMG (' int2str(i) ').dcm'])

Thank you for your answer.
I don't know why I didn't spot that earlier.
