Orthanc+OHIF DICOM Viewer最佳Dicom解析、在线浏览实践指南（解决方案）
概念

DICOM identifiers

Very importantly, the DICOM standard specifies DICOM tags that allow to index each single DICOM resource:
- Patients are indexed with PatientID (0x0010, 0x0020) (part of the patient module).
- Studies are indexed with StudyInstanceUID (0x0020, 0x000d) (part of the study module).
- Series are indexed with SeriesInstanceUID (0x0020, 0x000e) (part of the series module).
- Instances are indexed with SOPInstanceUID (0x0008, 0x0018) (part of the SOP module).
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:
- Create a DICOM server with the DICOM AET (Application Entity Title) ORTHANC that listens on the port 4242.
- Create a HTTP server for the REST API that listens on the port 8042.
- Store the Orthanc database in a folder called 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.

搭建

关闭防火墙
```
systemctl stop firewalld
```
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 replaces the default SQLite index of Orthanc by MySQL.
- libOrthancMySQLStorage.so.1.1 makes Orthanc store the DICOM files it receives into MySQL.
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",

  "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

访问Orthanc Explorer

http://node1:7101/app/explorer.html

orthanc-server http 接口

添加instances
```
curl -X POST http://localhost:7101/instances --data-binary @IM0
```
获取instances的studyid

```
安装OHIF DICOM Viewer

安装Meteor

将meteor-bootstrap-os.linux.x86_64.tar.gz文件和install.meteor.sh上传到/opt/soft目录下。

执行install.meteor.sh即可完成安装。
```
sh install.meteor.sh
```
Meteor环境需要git客户端依赖：
```
yum install -y git
```
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
