        The DICOM format is based on the ACR-NEMA specification, but adds a file
        header and a number of new tags.  ExifTool will extract information from
        either type of file.  The Tag ID's in the following table are the tag group
        and element numbers in hexadecimal, as given in the DICOM specification.

=head1 NAME

Image::ExifTool::DICOM - Read DICOM and ACR-NEMA medical images

=head1 SYNOPSIS

This module is used by Image::ExifTool

=head1 DESCRIPTION

This module contains routines required by Image::ExifTool to extract meta
information from DICOM (Digital Imaging and Communications in Medicine) DCM
and ACR-NEMA (American College of Radiology - National Electrical
Manufacturer's Association) ACR medical images.

=head1 NOTES

Values of retired elements in implicit VR format files are intepreted as
strings, hence they may not be displayed properly.  This is because the
specification no longer lists these VR's, but simply lists 'RET' for these
elements.  (Doh. Who's idea was that? :P)

Images compressed using the DICOM deflated transfer syntax will be decoded
if Compress::Zlib is installed.

No translation of special characters sets is done.
