changes dicom2 is a free command-line driven program which allows you to convert medical images and DICOM files to various other formats, while optionally performing some rudimentary image processing tasks... reads
DICOM file, or raw data-sets (ACR/NEMA). converts
non-encapsulated (native) syntax to PNG, BMP, TARGA, raw, DICOM (any syntax).
lists
DICOM tags in a human-readable form. allows
batch conversion. extracts
multiple-frame files. renames
destination files using user-defined pattern based on DICOM tags. accumulates
set of files into one image (to generate masks). provides
some image processing functions: mask, crop, halve, flip, window. is smallavailable for:

| dicom2 was not designed to handle all DICOM tricks, but I tried to extend its capabilities in some ways. It is (and will remain) freeware, but I would like to keep track of its users: feel free to send me any suggestions, advises or desires, as well as DICOM samples... | ||||||||

 Major
enhancements in the way the options will be processed.
 New
parameter ib added to the -d
and --syntax options, allowing
use of Implicit Big Endian syntax. Extended
the tolerance regarding very strange (and old) ACR/NEMA 2.0 files. |

Version 1.9n, 19 February 2007:
 This release fixes a minor bug that would occur when reading a few specific instances of Siemens NM files.Version 1.9m, 12 February 2007: This release fixes a few bugs people reported recently. Thank you for your feedback. Binaries are also about 13% smaller (not that they were really big, mind you).Version 1.9l, 7 March 2005: Wow, no update in a long time. This new release just fixes some bug people reported in the last few years (fortunately not too many). thank you guys. The only major change is that, at last, the DICOM dictionary file (dicom.din) is not needed anymore, it is bundled within the binary: no need to install it in awkward locations anymore, you can safely remove your old dictionary.Version 1.9h, 14 Jul. 2000: I
wish I had some time to document the changes and update this site :( Maybe
later in 2001. I'm still maintaining this software from time to time, removing
bugs and adding some functions.Version 1.8, 21 Jan. 1998: PNG
format supported (new -p option).
New
DICOM2 environment variable to set
default options. New
--compression option to control
the compression method used by some destination formats. New
--resample option to control
the resampling process (to 8 or 16 bits). New
--get=[max][:min][:mean] option to
get maximum/minimum/mean pixel values in frame. New
--timer option to time each call
to dicom2 (returns elapsed time).  I/Os
have been optimized. Expect 30% to 100% speed-up in some cases. Check performance
tests. New
parameters [=il|el|eb] added to -d,
allowing DICOM conversion to new syntax. New
parameter [=n] added to --halve,
allowing to halve many times in a single call. New
parameters [=center:width] added to --win,
allowing user-specified windowing arguments. New
optional [y|n] parameters added to --name,
--rank, --reverse,
--sort. Option
--nowarn has been replaced by option --warn[=y|n],
but remains for backward compatibility. The
resampling process has been slightly
modified when dealing with monochrome images (no min). Win
95/NT users: the Borland Redistributable Run Time DLL is no more needed :)
(see Download page)
Fixed
some very nice bugs and potential memory leaks (and introduced new one :).
Version 1.7, 18 Dec. 1997: Independent
version number added to the DICOM dictionary (displayed at start-up). Update
it. Windows
NT support (tested and updated to check dictionary in winnt/ directories).
New
accumulating mode --acc=min.
New
NT and Linux performance tests using a Pentium
II @ 300 mhz, 96 meg RAM.
A
minor bug corrupting MONOCHROME1conversion to TARGA
has been fixed. Small
changes in the DICOM dictionary. Update
it. Version 1.5, 1 Oct. 1997: Files
have been moved to a new location ! Planar
configuration 1 (color-by-plane) is now supported. Conversion
to true DICOM format is now supported. See -d.
New
"How to..." section describing how to
extract frames from multiple-frame files. Converting
a single frame from a multiple-frame file to DICOM is now supported.
New
renaming pattern fields: cur_fr
and cur_fr0, related to the current frame number. A
new --step=n option allows the user
to process every n-th file only.
Conversion
from RGB (color-by-pixel) is now supported, as well as samples/pixel > 1.
Access
to a particular frame in a multiple frames file is now allowed. See --frame.
Images
stored as a stream of bytes (VR = OB) are now handled correctly.
Sequences
Item (VR = SQ) are now stored correctly. BMP
format is now better supported (an alignment bug has been fixed).
TEXT
conversion is now performed before any image processing functions.
A
VR =DA and VR=TM bug has been fixed. dicom2
performs a bit faster. |
