  • SOP for GE Entegra

    According to the GE Genie dicom conformance statement there is a private storage sop so you could add the following line to dgatesop.lst


    Code
    GENIEPrivateStorage             1.2.840.113619.4.27             sop


    Make sure you only use spaces, not tabs between elements.

  • Deleting studies by modalities using command line

    Here is a solution you may wish to use. It is a perl program that generates a list of study or series UIDs based on modaliity and then feeds each one to --deletestudy or --deleteseries.


    If you don't already have perl you can get a free package from Activestate http://www.activestate.com/Products/activeperl/.


    Copy the following program and call it delete_by_modality.pl

    Code
    ## Create a list of study or series UIDs that match the given modality# and optionally delete them.# eg. delete_by_modality.pl --modality CT --series # Author: Mark Pearson markp@nucmed.crg.cs.nsw.gov.au#use Getopt::Long;sub rtrim;sub getStudyList;sub getSeriesList;my $dgateHome = 'C:\Conquest';my $dgate = "dgate.exe";my $modality = '';my $matchSeries = 0;my $matchStudy = 0;my $verbose = 0;my $delete = 0;my $help = 0;my $print = 0;my $test = 0;my $found = 0;my $deleted = 0;my $limit = 0;my @uids = ();$ret =  &GetOptions(	"modality=s" 	=> \$modality,	"limit=i"		=> \$limit,	"study" 		=> \$matchStudy,	"series" 		=> \$matchSeries,	"delete" 		=> \$delete,	"print"			=> \$print,	"verbose" 		=> \$verbose,	"noaction" 		=> \$test,	"help" 			=> \$help	);if (! $ret || $help) {	my $useage = "USAGE: delete_by_modality --options\n";	$usage .= "Options:\n";	$usage .= "\t--modality=XX\t\tfind all uids matching the modality XXX (manditory)\n";	$usage .= "\t--study or --series\tfind study or series UIDs (manditory)\n";	$usage .= "\t--delete\t\tdelete UIDs found.\n";	$usage .= "\t--noaction\t\tdo all actions except delete. Best with --verbose\n";	$usage .= "\t--print\t\tPrint a list of the UIDs found\n";	$usage .= "\t--limit=NN\t\tFind at most NN matches\n";	$usage .= "\t--verbose\t\tShow more detail of actions\n";	die $usage;}if (length($modality) == 0) {	die "ERROR: No modality specified. Use --modality=XXX\n";}if ($matchSeries && $matchStudy) {	die "ERROR: Specify --study or --series, not both\n";}chdir $dgateHome or die "ERROR: could not cd to $dgateHome\n";;if ($matchStudy) {	print "StudyUIDs that match modality $modality\n" if ($verbose);	@uids = getStudyList($modality, $limit);	foreach $uid (@uids) {		print "$uid\n" if ($print);		$found++;	}}if ($matchSeries) {	print "SeriesUIDs that match modality $modality\n" if ($verbose);	@uids = getSeriesList($modality, $limit);	foreach $uid (@uids) {		print "$uid\n" if ($print);		$found++;	}}print "$found UIDs found\n";if ($delete && $found == 0) {	die "WARNING: No UIDs found to delete\n";}if ($delete && $matchStudy) {	foreach $uid (@uids) {		$cmd = $dgate." --deletestudy:\"".$uid."\"";		if ($verbose) {			print "Call $cmd\n";		}		if (! $test) {			my $resp = `$cmd`;			$deleted++;		}	}}if ($delete && $matchSeries) {	foreach $uid (@uids) {		$cmd = $dgate." --deleteseries:\"".$uid."\"";		if ($verbose) {			print "Call $cmd\n";		}		if (! $test) {			my $resp = `$cmd`;			$deleted++;		}	}}print "$deleted UIDs deleted\n";if ($regen) {	$cmd = $dgate." --initializetables:";	if ($verbose) {		print "Call $cmd\n";	}	my $resp = `$cmd`;	$cmd = $dgate." --regen:";	if ($verbose) {		print "Call $cmd\n";	}	my $resp = `$cmd`;}exit;sub getStudyList($) {	my ($mod, $lim) = @_;	if ($lim) {		$cmd = $dgate." --query2:\"DICOMStudies|StudyInsta|StudyModal = '".$mod."'|%s|$lim\"";	} else {		$cmd = $dgate." --query:\"DICOMStudies|StudyInsta|StudyModal = '".$mod."'|%s\"";	}	if ($verbose) {		print "Call $cmd\n";	}	my $resp = `$cmd`;	my @suids = split("\n", rtrim($resp));	return @suids;}sub getSeriesList($) {	my ($mod, $lim) = @_;	if ($lim) {		$cmd = $dgate." --query2:\"DICOMSeries|SeriesInst|Modality = '".$mod."'|%s|$lim\"";	} else {		$cmd = $dgate." --query:\"DICOMSeries|SeriesInst|Modality = '".$mod."'|%s\"";	}	if ($verbose) {		print "Call $cmd\n";	}	my $resp = `$cmd`;	my @suids = split("\n", rtrim($resp));	return @suids;}# Right trim function to remove trailing whitespacesub rtrim {	my ($string) = @_;	$string =~ s/\0//g;	$string =~ s/\s+$//;	return $string;}


    If conquest is not installed in the default location the variable $dgateHome must be adjusted.


    To run the program, open a command shell and type in

    Code
    delete_by_modality.pl --modality CT --series --print1.2.840.113704.1.111.5700.1193965940.89999.9999.7.1196035999.2501.2.840.113704.1.111.4628.1193960088.201.2.840.113704.1.111.5076.1155781949.81.2.840.113704.1.111.5076.1155781894.41.2.840.113704.1.111.2664.1156723230.111.2.840.113704.1.111.5296.1156813228.87 UIDs found0 UIDs deleteddelete_by_modality.pl --modality CT --series --delete7 UIDs found7 UIDs deleted


    To find out what actions wouild be taken without deleting anything add the options --verbose --noaction.


    If there are a very large number of UIDs the program may run out of memory. In that case use the --limit option to restrict the number UIDs found.


    While testing on linux with conquest 1412c I found that if the dabase is Mysql the files were deleted but the database did not update and a manual database re-initialization was necessary. Neither dbase or postgres had these problems.


    To use the program on linux add the location the the perl binary to the top of the program and modify $dgateHome and $dgate

    Perl
    #!/usr/bin/perl

    #

    # Create a list of study or series UIDs that match the given modality

    .....

    my $dgateHome = '/usr/local/conquest/postgres';

    my $dgate = "./dgate";

    .....

  • Linux printing issue

    I just wanted to post an update of my analysis of this problem. My theory that the cfind demographics should be returned as LittleEndianImplicit is incorrect. I tried connecting to different dicom server that gave a correct response as LittleEndianExplicit.


    If I caputre data with wireshark from the two servers using LittleEndianExplicit it is able to decode the data from the other server but not from conquest.


    If I am able to track down the source of the problem I'll post it with a new subjet title.

  • Regeneration speed with mysql 5 Database

    The data used to populate the database tables comes from the dicom header in each file and must be extracted, formatted and inserted into the database by a dicom processing program, in this case conquest.


    Mysql and other database programs only know how to process SQL (database language) commands.

  • Linux printing issue

    After trying to read and understand the DICOM standard part 5 I have a possible explanation of the LittleEndianExplicit issue. In section 7.3 dealing with byte ordering there is a note as follows: Note:

    Quote

    The Command Set structure as specified in PS 3.7 is encoded using the Little Endian Implicit VR Transfer Syntax.


    I think this means that the entire cfind exchange must use LittleEndianImplicit.


    When LittleEndianExplicit is available dcmtk cfind returns the following:

    wireshark capture:


    The point to note is that the study demographic data is sent as LittleEndianExplicit when available, so even though the data on the wire is the same the interpretation is incorrect. I think the standard says that only the pixel data should be sent as LittleEndianExplicit.


    If the flag --propose-implicit is added to the dcmtk cfind then the correct result is returned, but our Philips nuclear medicine workstations just crash.

  • Linux printing issue

    I have discovered a problem with printing under linux using conquest 1413.


    In order for the dcmtk program findscu to work correctly, LittleEndianExplicit must be commented out in dgatesop.lst. When this happens printing stops.


    The only difference in the log output is that the line Print file: .... is missing.


    If LittleEndianExplicit is enabled again then the print files are generated.


    From the code in dgate.cpp (line 10465) it seems vr->SQObjectArray is not being populated.


    Does anyone have any possible solutions other than running multiple instances?

    For security reasons I have added a user "conquest" and the package authbind to allow access to priveleged ports.
    I added the following entries to dicom.ini:
    HomeDir = /usr/local/conquest
    StatusLog = /var/log/conquest/NMPACS.serverstatus.log
    TroubleLog = /var/log/conquest/NMPACS.PacsTrouble.log


    The file /etc/cron.weekly/conquest_rotate does weekly log rotation for me.



    This copes with multiple pacs instances on the same host. The advantage of using savelog is that old logfiles are compressed.
    It should be quite simple to edit the files to have executable or log in /opt.
    Also, don't forget to set the appropriate file permissions for the user that runs conquest.

  • 1.4.13 debuglevel bug

    There is a subtle bug in 1.4.13 (only tested on linux) with debuglevel set greater than 0. Using a command line option with a long format string will cause a segfault. Here is an example


    dgate --setdebuglevel:1
    dgate --get_amap:1,%s%s%s%s


    will cause a segfault, but dgate --get_amap:1,%s%s will not.


    I noticed that the logfile shows output like this:


    9999,0400 16 UN "get_amap:1,ðLõ(null)"


    The incorrect output is also produced in 1.4.12c, but it does not trigger the segfault.

  • Linux installation of ConQuest

    The compile line is
    g++ -I/path/to/include/file -DUNIX -DNATIVE_ENDIAN=1 -DNOINTJPEG -DPOSTGRES total.cxx -o dgate -lpthread -L/path/to/libpq -lpq
    There will be quite a few warnings, but they can be ignored.
    Don't compile on a 64 bit system as it is only 32 bit safe.


    In dicom.ini check that:
    PostGres = 1
    DoubleBackSlashToDB = 1

  • Windows GUI emulation

    Hi,


    I have a question about Query/Move in the windows version of conquest. I am tyring to emulate most of the windows GUI on linux but am stuck here. Does the GIU just call dgate with command line switches or does it use other programs/libraries for doing Query/Move?


    On linux, I have tried using --patientfinder:srv|str|fmt|file to query other dicom hosts, but it only queries the local host, and a note in the source code that the srv is ignored confirms this.


    My next option is to try using the dcmtk programs for these functions.

  • display of large files

    This is covered in the manual. Search for largefile to find it.


    There is a setting in dicom.ini: LargeFileSizeKB = 1024.


    Any image over this file size will not be displayed by default, so increase it to the size of your files.

  • Port Number Limitations

    I don't think the limit comes from Conquest. I can use port 50089 on my linux system without any problems. I don't have access to windows system at the moment to do other testing.


    I could be a privilege problem and may also depend on the version of windows you are using and the rights of the user. More details of your setup would be useful.

  • Compilation tool for linux

    As an aid for compiling conquest under linux, I have created a command file for using cmake (http://www.cmake.org/HTML/Index.html).


    cmake is an alternative to automake and uses a single configuration file called CMakeLists.txt. Installation of cmake should be simple as binary packages are available for most linux distributions including red hat and debian based systems.


    The CMakeLists.txt file plus some basic instructions are available at http://www.nmrf.org.au/conquest/conquest_cmake.html


    More instructions and tips for using conquest on linux will be added as time permits.

  • Database Editing

    If you do edit the database directly then you cannot do a re-initialize. If you re-initialize, the records are deleted (along with your changes) and new data is inserted.


    In general you should avoid manually editing the database files directly as conquest does not know about it and the changes may not accuratly reflect the contents of the dicom files.


    You should probably either
    - add a forwarding rule that makes the changes you want
    or
    - use an external program such as dcmodify from DCMTK toolkit to modify the files and then use the command line option --regenfile:file to update the database

  • I want to or How can I...

    You could use the command line options to do that --query:table|fields|where|fmt|file


    dgate --query:"DICOMPatients|PatientID,PatientNam,PatientSex,PatientBir||%s,%s,%s,%s|demographics.txt"


    Data will be written to demographics.txt. A where clause can be added to limit data.
