Abstract
Since
the publication of DICOM standard part 10 about file format, DICOM leaves
untouched 128 bytes in the beginning of each file for extra metadata
accessed directly. This space can be used to declare the file as being a
TIFF file, additionally to being a DICOM one. This article demonstrates how
to create such hybrid file. TIFF allows for pixel depth of 16
bits-per-channel and may integrate an input ICC color management profile in
order to represent the image correctly. We explain how to use this feature
so that the TIFF representation automatically conforms to the result which
would be expected if the picture data would pass through a DICOM graphical
pipeline. Opening hybrid DICOM-TIFF16-ICC fastens the reopening of huge sets
of files thanks to highly optimized TIFF and ICC libraries already embedded
in the newest operating systems. It is also a very promising option for the
transmission of medical image outside of DICOM networks (embedded within PDF
documents, burnt on CD, sent by http wado to a web
browser).
