Why is DICOMREAD unable to read my JPEG-2000 encoded image using the Image Processing Toolbox 6.4 (R2009b)?

When I try using DICOMREAD to read in my JPEG-2000 encoded image, I get the following error:

 j2convert

 ??? Error using ==> dicomread>newDicomread at 223

 Unsupported data encoding.

 Error in ==> dicomread at 78

     [X, map, alpha, overlays] = newDicomread(msgname, frames);

 Error in ==> j2convert at 4

 a=dicomread('K:\matlabexj2000\comp\DICOM\IMA00000034');

This enhancement has been incorporated in Release 2010b (R2010b). For previous product releases, read below for any possible workarounds:

JPEG-2000 encoded images are not supported in the Image Processing Toolbox 6.4 (R2009b). To work around the issue, use another program to convert the image to a supported format before reading it in using MATLAB.
