概念
DICOM identifiers
Very importantly, the DICOM standard specifies DICOM tags that allow to index each single DICOM resource:
PatientID (0x0010, 0x0020) StudyInstanceUID (0x0020, 0x000d) SeriesInstanceUID (0x0020, 0x000e) SOPInstanceUID (0x0008, 0x0018)
The DICOM standard orders StudyInstanceUID , SeriesInstanceUID and SOPInstanceUID to be globally unique . In other words, it is mandatory for two different imaging devices to never generate the same identifiers, even if they are manufactured by different vendors. Orthanc exploits this rule to derive its own unique identifiers .
Importantly, even if the PatientID must be unique inside a given hospital, it is not guaranteed to be globally unique. This means that different patients imaged in different hospitals might share the same PatientID . For this reason, you should always browse from the study level (and not from the patient level) as soon as you deal with an application that handles patients from different hospitals.
Configuration of Orthanc
Configuring Orthanc simply consists in copying and adapting the default configuration file . This file is in the JSON file format. You can generate a sample configuration file with the following call:
$ Orthanc --config=Configuration.json
Then, start Orthanc by giving it the path to the modified Configuration.json path as a command-line argument:
$ Orthanc ./Configuration.json
The default configuration file would:
ORTHANC OrthancStorage
Remark: When specifying paths under Microsoft Windows, backslashes (i.e. \
) should be either escaped by doubling them (as in \\
), or replaced by forward slashes (as in /
).
To obtain more diagnostic, you can use the --verbose
or the --trace
options:
$ Orthanc ./Configuration.json --verbose $ Orthanc ./Configuration.json --trace
Starting with Orthanc 0.9.1, you can also start Orthanc with the path to a directory. In such a case, Orthanc will load all the files with a .json
extension in this directory, and merge them to construct the configuration file. This allows to split the global configuration into several files.

安装orthanc-server
依赖环境
yum install unzip make automake gcc gcc-c++ python cmake curl-devel \ libpng-devel sqlite-devel libuuid-devel openssl-devel \ lua-devel mercurial patch tar
编译安装
解压Orthanc-1.4.2.tar.gz到 /opt/context/Orthanc-1.4.2,进入目录执行:
cmake -DALLOW_DOWNLOADS=ON \ -DUSE_SYSTEM_JSONCPP=OFF \ -DUSE_SYSTEM_MONGOOSE=OFF \ -DUSE_SYSTEM_PUGIXML=OFF \ -DUSE_SYSTEM_SQLITE=OFF \ -DUSE_SYSTEM_BOOST=OFF \ -DUSE_SYSTEM_DCMTK=OFF \ -DUSE_SYSTEM_GOOGLE_TEST=OFF \ -DUSE_SYSTEM_LIBJPEG=OFF \ -DCMAKE_BUILD_TYPE=Release \ /opt/context/Orthanc-1.4.2 cmake -DALLOW_DOWNLOADS=ON \ -DUSE_SYSTEM_JSONCPP=OFF \ -DUSE_SYSTEM_CIVETWEB=OFF \ -DUSE_SYSTEM_PUGIXML=OFF \ -DUSE_SYSTEM_SQLITE=OFF \ -DUSE_SYSTEM_BOOST=OFF \ -DUSE_SYSTEM_DCMTK=OFF \ -DUSE_SYSTEM_GOOGLE_TEST=OFF \ -DUSE_SYSTEM_LIBJPEG=OFF \ -DCMAKE_BUILD_TYPE=Release \ /opt/context/Orthanc-1.5.6 make
see:https://bitbucket.org/sjodogne/orthanc/src/default/LinuxCompilation.txt?fileviewer=file-view-default
其中/opt/context/Orthanc-1.4.2是解压到的目录,根据实际情况酌情修改。
如果Downloading http://www.orthanc-server.com/downloads/third-party/boost_1_67_0_bcpdigest-1.4.0.tar.gz下载不稳定,将出现file DOWNLOAD HASH mismatch错误,将残缺的文件从/opt/context/Orthanc-1.4.2/ThirdPartyDownloads/目录下删除,手动使用迅雷下载再上传到该目录下即可。
如果遇到文件不存在的问题,则手动解压ThirdPartyDownloads目录下对应的压缩包到Orthanc-1.4.2目录下。
如果遇到各种奇怪的错误,那么使用迅雷手动下载全部文件,然后上传即可。
编译OrthancDicomWeb插件
将OrthancDicomWeb-0.5.tar.gz解压到/opt/context/Orthanc-1.4.2-plugins/OrthancDicomWeb-0.5目录
进入/opt/context/Orthanc-1.4.2-plugins/OrthancDicomWeb-0.5执行:
cmake -DSTATIC_BUILD=ON -DCMAKE_BUILD_TYPE=Release make
最终生成libOrthancDicomWeb.so.0.5插件文件
编译MySQL plugins插件
将OrthancMySQL-1.1.tar.gz解压到/opt/context/Orthanc-1.4.2-plugins/OrthancMySQL-1.1目录
进入/opt/context/Orthanc-1.4.2-plugins/OrthancMySQL-1.1/MySQL执行:
cmake -DSTATIC_BUILD=ON -DCMAKE_BUILD_TYPE=Release make
The compilation will produce 2 shared libraries, each containing one plugin for Orthanc:
libOrthancMySQLIndex.so.1.1 libOrthancMySQLStorage.so.1.1
使用OrthancMySQL插件将dicom元数据存储到 MySQL 中,不仅仅只是为了更好的性能和可靠性,更重要的是为实现Orthanc负载均衡打基础,非常重要!!!如果您不需要长远考虑,那么可以跳过此步骤,直接使用默认内置的本地 SQLite 数据库。
配置
配置文件在/opt/context/Orthanc-1.4.2/Resources目录下Configuration.json。
只需要关注以下几项即可:
//服务名称 "Name" : "JuniperOrthanc" //dicom文件存储路径 "StorageDirectory" : "/data/orthanc", //索引数据库存储路径 "IndexDirectory" : "/data/orthanc", //插件配置 "Plugins" : [ "/opt/context/Orthanc-1.4.2-plugins/OrthancDicomWeb-0.5/libOrthancDicomWeb.so.0.5", "/opt/context/Orthanc-1.4.2-plugins/OrthancMySQL-1.1/MySQL/libOrthancMySQLIndex.so.1.1", "/opt/context/Orthanc-1.4.2-plugins/OrthancMySQL-1.1/MySQL/libOrthancMySQLStorage.so.1.1" ], //OrthancDicomWeb插件配置 "DicomWeb" : { "Enable" : true, // Whether DICOMweb support is enabled "Root" : "/dicom-web/", // Root URI of the DICOMweb API (for QIDO-RS, STOW-RS and WADO-RS) "EnableWado" : true, // Whether WADO-URI (previously known as WADO) support is enabled "WadoRoot" : "/wado", // Root URI of the WADO-URI (aka. WADO) API "Host" : "localhost", // Hard-codes the name of the host for subsequent WADO-RS requests "Ssl" : false, // Whether HTTPS should be used for subsequent WADO-RS requests "StowMaxInstances" : 10, // For STOW-RS client, the maximum number of instances in one single HTTP query (0 = no limit) "StowMaxSize" : 10, // For STOW-RS client, the maximum size of the body in one single HTTP query (in MB, 0 = no limit) "QidoCaseSensitive" : true // For QIDO-RS server, whether search is case sensitive (since release 0.5) }, //Mysql插件配置 "MySQL" : { "EnableIndex" : true, //使用mysql存储文件索引 "EnableStorage" : false, //使用mysql存储dicom文件 "Host" : "node3", // For TCP connections (notably Windows) "Port" : 3306, // For TCP connections (notably Windows) "UnixSocket" : "", // For UNIX on localhost, Linux set to blank "Database" : "orthanc", "Username" : "root", "Password" : "123", "Lock" : false // 单个orthanc server独占数据库,如果使用多个orthanc server共享mysql数据库,必须关闭 }, //http服务端口 "HttpPort" : 7101, //允许远程访问 "RemoteAccessAllowed" : true,
生产环境的配置文件请在测试环境配置文件的基础上做修改,因为做了许多优化
mkdir -p /data/orthanc
mysql数据库初始化
开启Mysql超长索引字段
show variables like 'innodb_large_prefix';
set global innodb_large_prefix=1;
show variables like 'innodb_file_format';
SET GLOBAL innodb_file_format = BARRACUDA;
set global innodb_file_format_max=BARRACUDA;
在配置的mysql服务中创建orthanc数据库,字符集utf8mb4 -- UTF-8 Unicode,排序规则utf8mb4_unicode_ci
然后在orthanc数据库中执行OrthancMySQL-1.1.sql即可。
启动关闭
#进入/opt/context/Orthanc-1.4.2目录,编译完成之后这里有可执行文件 #启动 ./Orthanc /opt/context/Orthanc-1.4.2/Resources/Configuration.json > /data/logs/orthanc/orthanc.log 2>&1 & #关闭 ./Orthanc stop kill pid
/data/logs/orthanc/orthanc.log为日志文件路径

安装OHIF DICOM Viewer
将Viewers-master.zip解压到/opt/context/ohif-dicom-viewer目录
进入/opt/context/ohif-dicom-viewer/OHIFViewer目录,利用Meteor安装OHIF DICOM Viewer依赖:
METEOR_PACKAGE_DIRS="../Packages" meteor npm install
配置
编辑/opt/context/ohif-dicom-viewer/config/orthancDICOMWeb.json
关注以下几点:
"name": "JuniperOrthanc", "wadoUriRoot": "http://localhost:7101/wado", "qidoRoot": "http://localhost:7101/dicom-web", "wadoRoot": "http://localhost:7101/dicom-web",
启动
进入/opt/context/ohif-dicom-viewer/OHIFViewer目录,利用Meteor启动OHIF DICOM Viewer:
METEOR_PACKAGE_DIRS="../Packages" nohup meteor --settings ../config/orthancDICOMWeb.json --allow-superuser > /data/logs/orthanc/ohif-viewer.log 2>&1 &
关闭
kill -9 `ps ax | grep meteor | awk '{print $1}'`
一定要用exit命令退出shell,否则meteor会自动停止
