MATLAB: Using multiselect uigetfile with dicomread

dicomreadmultiselectuigetfile

I have been using uigetfile to select dicom images which I then want to read with the dicomread command (I am using the image processing toolbox and Matlab version R2012b). If I select a single file then my code works fine:
    [name, pathname] = uigetfile('*.dcm', 'Select a reference DICOM file...', 'MultiSelect', 'on') ;
    for count = 1 : numel(name)
      imageref{count} = dicomread(name(count));  
   end
but for multiple files I get the error:
Error using dicomread>newDicomread (line 164)
The first input argument must be a filename or DICOM info struct.
Error in dicomread (line 80)
[X, map, alpha, overlays] = newDicomread(msgname, frames);
Error in register_CT (line 13)
    imageref{count} = dicomread(name(count));
I know that for multiple selections on uigetfile the filenames are cell strings, but if I convert them to character strings using the following code:
imageref{count} = dicomread(char(name(count))) ;
Then I get the error:
Error using dicomread>getFileDetails (line 1378)
File "IM-0001-0001.dcm" not found.
Error in dicomread>newDicomread (line 173)
fileDetails = getFileDetails(filename);
Error in dicomread (line 80)
[X, map, alpha, overlays] = newDicomread(msgname, frames);
Error in register_CT (line 13)
    imageref{count} = dicomread(char(name(count))) ;
Where am I going wrong?!

You probably need to pass in the full path to your DICOM file to dicomread(). Try this:
for count = 1:numel(name)
  imageref{count} = dicomread( fullfile(pathname, name{count}) );
end
