What is wrong with this code?
显示 更早的评论
Code:
Function dcm = dcm2vol(din)
%%import dicom volume
ls = dir(fullfile(din,'*.dcm'));
s = size(ls);
tmp = dicomread([din,'\',ls(1).name]);
si = size(tmp);
Yr = NaN(si(1),si(2),s(1));
Yr(:,:,1) = tmp;
for i = 2:s(1)
Yr(:,:,i) = dicomread([din,'\',ls(i).name]);
end
dcm = Yr;
end
din refers to directory. However when i use this as the directory i get error.
>> dcm = dcm2vol(C:\Users\ying0018\Documents\MATLAB)
dcm = dcm2vol(C:\Users\ying0018\Documents\MATLAB)
↑
Error: Unexpected MATLAB operator.

Replace
dcm = dcm2vol(C:\Users\ying0018\Documents\MATLAB)
by
dcm = dcm2vol('C:\Users\ying0018\Documents\MATLAB')

Here are some other comments about the code to help with readability, etc:
Function dcm = dcm2vol(din) %<-- "function" must be lowercase
%%import dicom volume
ls = dir(fullfile(din,'*.dcm')); %Don't use "ls" as a variable since "ls" a function
s = size(LS);
tmp = dicomread([din,'\',LS(1).name]); %Use "fullfile" like you did above, or "filesep" instead of '\' to be platform independent.
%I see you want to preallocate but don't know the size yet. Your method
%works, but for readability, see the other method too.
si = size(tmp);
Yr = NaN(si(1),si(2),s(1)); %Will there be any NaN values after dicomread?
Yr(:,:,1) = tmp;
for i = 2:s(1)
Yr(:,:,i) = dicomread([din,'\',LS(i).name]);
end
dcm = Yr; %<-- No need to use temp variable Yr when it's same as dcm
Here's a rewritten version of your code:
function dcm = dcm2vol(din)
%%import dicom volume
LS = dir(fullfile(din,'*.dcm'));
s = size(LS);
Yr = cell(s(1), 1);
for i = 1:s(1)
Yr{i} = dicomread(fullfile(din,LS(i).name));
end
dcm = cat(3, Yr{:});
To run dcm2vol, see @per isakson's comment above (which is the answer to your original error)
