DICOM Services
The DICOM protocol consists of many different services, most of which involve transmission of data over a network. The program supports the store, query/retrieve and echo services (C-STORE/C-FIND/C-MOVE/C-ECHO SCU).

Store Service (C-STORE)
The DICOM Store service is used to send images or other persistent objects to a PACS or workstation.

Query/Retrieve Service (C-FIND/C-MOVE)
This service enables a workstation to find lists of images or other objects and then retrieve them from a PACS system.

Echo Service (C-ECHO)
This sevice enables a workstation to verify the connection and the communication with another workstation or a PACS system.

DICOM communication protocol
The communication protocol is an application protocol that uses TCP/IP to communicate between systems. DICOM files can be exchanged between two entities that are capable of receiving image and patient data in DICOM format.

Communication between DICOM nodes
Two DICOM nodes (workstations, PACS systems) can communate if they know each other. That means, each system must know the AE Title, the IP address or hostname and the IP port of the other system. 

AE Title
AE Title or AET is an abbreviation for Application Entity Title. An AE Title is used by an Application Entity (AE) to identify itself. AE Titles need to be locally unique and are typically managed by a system administrator. They are case-sensitive and 16 bytes long. They are to be configured prior to initializing a DICOM connection.

IP Address
An Internet Protocol (IP) address is a numerical identification (logical address) that is assigned to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes. Although IP addresses are stored as binary numbers, they are often displayed in more human-readable notations, such as 192.168.100.1 . Usually can be translated into a hostname via the local hosts file, or the Domain Name System (DNS) resolver, and can be used instead of the hostname.

Hostname
A hostname is a domain name assigned to a host computer, and is translated into an IP Address via the local hosts file, or the Domain Name System (DNS) resolver. It can be used instead of an IP Address.

Port
TCP/IP protocol uses the notion of port numbers to identify sending and receiving application end-points on a host. Each side of a TCP connection has an associated 16-bit unsigned port number (1-65535) reserved by the sending or receiving application. Arriving TCP data packets are identified as belonging to a specific TCP connection by its sockets, that is, the combination of source host address, source port, destination host address, and destination port. Ports need to be locally unique and are typically managed by a system administrator. The numbers 104 and 11112 are usually used as IP Ports in DICOM networking, but any number between 1 and 65535 can be used, but it must be unique for the host (node/PC), and it must not be used from any other application.

Firewall
A firewall is a dedicated software, which inspects network traffic passing through it, and denies or permits passage based on a set of rules. If there is a firewall in your computer you have to unblock the application.

Configuration

Configure the Sante DICOM application
Select the menu command "OptionsNetwork Setup".
A dialog box appears and allows you to insert the AE Title and the IP Port of Sante DICOM application. Also, it allows you to insert the AE Title, IP address and port of your PACS systems.
The program supports up to 8 PACS servers.




Insert/Edit a PACS system
Press the "Insert" or "Edit" buttons of the above dialog box. A new dialog box appears and allows you to insert the information of your PACS system.




Configure your PACS server
The Sante DICOM application is compatible with the most DICOM PACS providers. Please advise your PACS software help file about AE configuration of your PACS server. Below are examples of the configuration of two of the most used free PACS servers, the ConQuest and the dcm4chee. All PACS servers have similar configuration with these ones.


The ConQuest configuration
Select the "Known DICOM providers" tab and insert the AE Title, IP Address and IP Port of Sante DICOM Application.
Press the "Save this list" button.




The dcm4chee configuration
Select the "AE Managment" tab, press the "+ new AET" button and insert the AE Title, IP Address and IP Port of Sante DICOM Application.

Send files/series to a PACS server (C-STORE service)

Use the menu command "FileSend Send To C-STORE SCP" to send the active DICOM file or DICOM series to a C-STORE SCP server. This command is active when you have opened one or more DICOM files and/or series, and you have configured the DICOM neworking.



AE Title combo box
Selects a C-STORE SCP server.

Echo button
Tests the connection with the selected C-STORE SCP server.

OK button
Sends the selected entries to the selected C-STORE SCP server and closes the dialog box.

Cancel button
Interrupts the procedure and closes the dialog box.

Network log
The user can view the log of a specific network job by selecting the desired row in the Network Status pane.



A dialog box appears and displays the details of the job.

Query and retreive (C-FIND/C-MOVE services)

Use the menu command "FileQuery C-STORE SCP" to query and retreive DICOM series and studies from a PACS server. This command is active when you have configured the DICOM neworking.
The transferred series and studes are stored in the local database.
