Comprehensive Features & Specifications

PacsGreen Server is a DICOM compliant PACS (Picture Archive and Communication System) application that combines the following components in one server or one box:

  • A DICOM server.
  • A PACS server which uses open source MySQL database.
  • A Web server which uses open source Apache 2.0 HTTP server and PHP (recursive acronym for "PHP: Hypertext Preprocessor") scripting engine for web user interface.

The benefits of PacsGreen versus the traditional PACS servers are:

  • It is low-cost since it uses open source MySQL database and Apache web servers.
  • It is less complicated. It makes the life of a PACS administrator a lot easier since there is only ONE instead of multiple servers or boxes to maintain.
  • Choose your favorite hardware platform, whether it is a PC, workstation, fully-fledged server with RAID disk arrays, blade server or even a laptop, to install and run PacsGreen server software.
  • Choose your favorite software operating system, whether it is Linux, Mac OS X, Windows NT, Windows 2000, Windows XP, Vista, Windows 2003/2008/2012 Server, or Windows 7/8.
  • IT infrastructure integration. Archiving of the PACS database is just as simple as backing up files on a regular server, which makes PacsGreen fit seamlessly into the rest of IT infrastructure of the entire organization. A PACS administrator has the freedom to choose their favorite backup solutions, software and/or archive media.

PacsGreen Server offers the following features:

  • Super-User/Administrator 'root' has all of the above privileges.
  • All patients/studies stored in PacsGreen database are Private when they're received. Only users with 'Modify' privilege can change a patient/study from Private to Public, or vice versa.
  • Public patients/studies can be viewed by any user, but Private patients/studies can only be viewed by users with 'View' privilege.
  • Changing a patient from Private to Public will implicitly change all studies of the patient to Public, regardless of their previous settings.
  • Changing a patient from Public to Private will implicitly change all studies of the patient to Private, regardless of their previous settings.
  • Changing a study from Private to Public does not affect the privacy setting of the patient who this study belongs to, except when this study is the only study of the patient. The patient will also be changed from Private to Public if and only if the study being changed is the only study of that patient.
  • Changing a study from Public to Private does not affect the privacy setting of the patient who this study belongs to, except when this study is the only study of the patient. The patient will also be changed from Public to Private if and only if the study being changed is the only study of that patient.
  • Public patients/studies can be viewed by all users.
  • For Private patients/studies, if the current logged-in User does not have the 'View' privilege enabled, then the Lastname and Firstname stored in the current user profile will be checked to see if they match with either the Referring Physician Name or the Reading Physician Name. The Private patient/study is accessible if the lastname and firstname of the current user match with either the Referring Physician Name or the Reading Physician Name, or if the User belongs to a User Group that can access the private patient/study (see below).
  • For Private patients/studies, if the current logged-in Group User does not have the 'View' privilege enabled, then the Group Description stored in the current Group User's profile will be checked to see if they match with the Institution Name of the private patient/study. The Private patient/study is accessible only if the Group Description of the current Group User match with the Institution Name of the patient/study.
  • System Administration privilege is required in order to review, modify or delete system-level configuration information, e.g., the System Configuration, Email Server, System Journal, System-level Job Status pages, etc.
New Web User Interface Page(s) There's a new User Administration page added and it can be access from the User Administration link when logged in as super-user/administrator 'root'. From this page, the super-user/administrator 'root' can create new users, delete existing users, or modify privileges for existing users. This page cannot be accessed by any other user.
Based on the User Administration Rules listed above, there are three (3) categories of users for PacsGreen Server :

Category

Description

Administrator This is the pre-defined Administrator account 'root'. There is only one such account and it is required for all user administration tasks.
System Administrators These are the user accounts with the System Administration privilege Enabled by the Administrator. These users can access system-level configuration information such as the Email Server, System Configuration, Journal, or System-level Job Status pages, etc.
Power Users These accounts usually have the 'Modify' and 'View' privileges enabled by the Administrator. These users can access all patients/studies stored in the PacsGreen Server database, they can also modify or delete existing database records.
Regular Users These accounts do not have the 'Modify' or 'View' privileges and they are usually created for the referring physicians or reading physicians. These users can only read existing database records but cannot modify them, they can access only those Private patients/studies with matching Referring Physician Name or Reading Physician Name.
More Transfer Syntaxes Supported In addition to the default Implicit Little Endian transfer syntax, PacsGreen Server  also supports the following transfer syntaxes:

Query/Retrieve By Date/Time PacsGreen Server supports the additional Range Matching by Date/Time method for the Query/Retrieve SOP classes.
Query/Retrieve Remote SCP Pages In addition to the currently supported feature of Querying All Patients in remote Query/Retrieve SCP applications, a new Search Remote SCP page has been added to offer the same search capabilities as searching the local PacsGreen Server database:

  • Search by Patient ID, Patient Name
  • Search by Study ID, Study Date, Study Time, Accession Number
  • Search by Series Date, Series Time, Modality
  • Wild-card characters '*' and '?' can be used and the search results depend on whether the remote Query/Retrieve SCP supports the wild-card character matching method or not.
Automatic Image Routing PacsGreen Server  supports a User-Defined Automatic Image Routing Table, which consists of either a source application entity (AE) title or a routing key attribute, a destination AE title, a fixed 24-hour schedule or a [From, To] window, and the option to automatically purge received images after they have been routed successfully to the destination AE(s).

  • Route By Source AE Title: 
    When an image is received from a source AE, if the Source AE Title matches with one or more entries defined in the automatic routing table, then the received image will be forwarded automatically to one or more destination AE(s) defined for the matching source AE title, based on the specified schedule, which can be either as soon as received (Immediately), between a [From, To] window, or a 24-hour clock interval, e.g., 7:00 P.M.
  • Route By Key Attributes: 
    Users can also define a Matching Pattern String with wild-card characters like '*' and '?' for routing by key attribute tags such as Patient ID (0010,0020), Referring Physician's Name (0008,0090), Institution Name (0008,0080), or Protocol Name (0018,1030). When an image is received from a remote AE, if the key attribute tag matches with the routing key pattern defined in the automatic routing table, then the received image will be forwarded automatically to one or more destination AE(s) specified for the matching key atribute, based on the specified schedule, which can be either as soon as received (Immediately), between a [From, To] window, or a 24-hour clock interval, e.g., 7:00 P.M.
  • Automatically Purge Received Images After Routing: 
    After the images have been successfully routed to the destination AE(s), users can choose whether or not to delete the received images by enabling or disabling the Auto Purgevariable of the specified route entry. By default, Auto Purge is Disabled so that received images will not be purged automatically after they have been routed.

If the auto-routing did not succeed after the first try, PacsGreen Server will retry for a maximum of 3 (default) attempts to deliver the failed images to the destination AE.

Importing External Patients/Studies PacsGreen Server supports importing/reading external patients/studies stored in DICOM Media Stoarage Formatted (with or without DICOMDIR directory record) CD/DVD/Dual-Layer DVD media, such as CD/DVD-ROM, CD-R/RW, DVD-R/RW/RAM or DVD+R/RW, into PacsGreen Server database.
Exporting Patients/Studies PacsGreen Server  supports exporting/writing patients/studies stored in PacsGreen Server database to a local directory using DICOM Media Storage Service Formats (with DICOMDIR directory record), which can then be archived to CD-R/RW, DVD-R/RW/RAM or DVD+R/RW long-term storage media using a CD/DVD/Dual-Layer DVD burner. Users can optionally compress exported volumes into ZIP files which can be downloaded after the export is completed. User can also optionally include external viewer program files when exporting patients, studies, series to CD/DVD/Dual-Layer DVD media, so that the images exported can be viewed from the included viewer application on the CD/DVD.
Printing Color and Grayscale Images From Anywhere With A Browser PacsGreen Server  supports Dicom Basic Grayscale and Color Print Management SOP classes as a SCU, so users can select a list of patients, studies, series or images from a browser after logging into PacsGreen, and print them out to any Dicom-compliant printer from anywhere in the world.
Study and Image Notes PacsGreen Server supports Bulletin-Board Style Online Discussions about a subject study or image. Users with the Upload privielege can also upload text files, Word/PDF documents, ZIP files, or even audio/video clips as attachments to any study note or image note.
Periodic Statistics Report PacsGreen Server supports statistics reports for studies received on a daily, weekly, monthly basis or a user-defined time period. A daily/weekly/monthly statistics report email will be automatically sent to the Administrator if the Administrator's email address and a SMTP server are configured.
System Journal Log PacsGreen Server supports HIPAA Auditing requirements by logging user activities to a System Journal Log. A monthly System Journal Log will be emailed automatically to the Administrator if the Administrator's email address and a SMTP server are configured.
Automatic Logout Browser Sessions PacsGreen Server supports the enhanced security feature to automatically logout browser sessions if they have been idle for certain period of time (default is 10 minutes).
Automatic Password Expiration PacsGreen Server supports the enhanced security feature to automatically expire user passwords after a fixed period (default is 60 days), and force the users to select a new password before they can login again.
Automatically Purging Aged Archive Directories Users of PacsGreen Server can optionally enable this Automatic Archive Directory Purging feature by defining a Low-Water Mark and High-Water Mark in terms of disk usage percentages. Once the disk usage percentage of the archive directories drops below the user-defined low-water mark, PacsGreen Server will start purging older studies stored in the archive directories based on the date the studies were received. PacsGreen Server will complete purging older studies after the disk usage percentage has risen above the user-defined high-water mark.
Synchronization with Remote Studies Users of PacsGreen Server can optionally enable this Remote Study Synchronization feature by selecting up to 24 hourly schedules, when they define a remote AE that supports Dicom Query/Retrieve functions as a SCP. Users can select whether to synchronize all studies or only those recent studies received within the last N days.
Upload Dicom Images from Web Browsers Users of PacsGreen Server can upload Dicom Part-10 formatted raw images from any web browsers (e.g., MSIE, FireFox, etc.) into the PacsGreen Server database.
Automatic-Scan for Importing Dicom Images PacsGreen Server can automatically scan a pre-defined local source directory periodically, and import any Dicom Part-10 formatted raw images (*.dcm) into the PacsGreen Server database.
Multiple Server Instances of PacsGreen Server PacsGreen Server supports multiple server instances running simultaneously on different TCP port numbers. To set up more than one instance of PacsGreen Server, just run the 'Setup.exe' in the PacsGreen Server installation directory and specify a new AE title and TCP port number. The log files for all PacsGreen Server instances are kept under the 'log' sub-directory of where PacsGreen Server was installed, with one sub-directory for each AE title of PacsGreen Server instance.
Server Instance Monitoring PacsGreen Server supports monitoring of server instances or processes. If any server instance/process exits abnormally for any reason whatsoever, a new server instance will automatically be started to eliminate service downtime.
Performance and Scalability Starting with version 3.1.1, PacsGreen Server has implemented significant database optimizations which improve the overall performance by an order of magnitude. These optimizations have enabled PacsGreen Server  database to reach the 100 million plus (100,000,000+) images mark while still maintaining good query response time for both the web and Dicom client applications, on a single server with one (1) Pentium 4 CPU at 3.0 GHz and 1 GB of RAM. With an open-source database such as MySQL as the backend, you can be rest-assured that the benchmarks will only grow much higher as MySQL and PacsGreen Server improve over time.

We also offer custom installation services by phone or remote desktop, other technical support services, as well as custom integration/feature developments that may be purchased on-demand. For detailed pricing information about these optional services, please contact us.
