Hi everybody,
I have some problems while reading DICOM files: if I issue the command
>> info = dicominfo(filename);
the field NumberOfFrames in the structure info contains the correct number of frames (it's a movie file). However, if I try to read the file by using the command
>> data = dicomread(filename);
all I get is the first frame in the movie. As a consequence, data is a 3-dimensional matrix, while it should be 4-dimensional (I am able to read the DICOM files with external software and I would like to be able to do the same in Matlab to perform some post-processing). If it may help, I am able to read grayscale frames, but have trouble when the frames are RGB images. I am using Matlab R2008b.

Any help would be greatly appreciated.

Would it be possible for you to send me one of the files that has this problem?  I'd be happy to take a look at it and try to get you a solution.
