Hi Elmar,
the DICOM standard is not directly supported by imaq read file function. The file format can be a standard format (BMP, TIFF, JPEG, PNG, and AIPD) or a nonstandard format known to the user. You could try to read the raw format directly or you can do an extra conversion. Files can be compressed using lossy or lossless variants of the JPEG format, as well as a lossless Run-Length Encoding format (which is identical to the packed-bits compression found in some TIFF format images).
