3 1 Introduction 1.1 Overview PACSMail is a DICOM 3 compliant medical device that allows disparate users to share any DICOM data for review and reporting. PACSMail relies on the DICOM standard to acquire data from a variety of sources including, PACS, workstations, modalities, removable media (CDs etc) and any DICOM compliant software device. For the purpose of this document PACSMail refers to a group of Windows programs and services that are part of the PACSMail managed service designed and developed by Sybermedica Ltd. Note that PACSMailPro and PACSMailMobile support the same functionality as PACSMail. 1.2 Change History Version Author Reason Date 01_00DICOM Conformance Alan Grace Initial Version 21-Jan-09 Statement 01_02DICOM Conformance Andrea Harry Review 25-Jan-09 Statement 01_03DICOM Conformance Dave Harvey Review 02-Feb-09 Statement 01_04DICOM Conformance Alan Grace Revision 02-Feb-09 Statement 01_04DICOM Conformance Statement Alan Grace Final Version 03-Feb Definitions ACR AE AET ASCII DB DICOM DIMSE DIMSE-C DIMSE-N GUI HIS IOD ISO NEMA RIS OSI PACS PDU American College of Radiology Application Entity Application Entity Title American Standard Code for Information Interchange Database Digital Imaging and Communications in Medicine DICOM Message Service Element DICOM Message Service Element- Composite DICOM Message Service Element- Normative Graphical User Interface Hospital Information System Information Object Definition International Standard Organization National Electrical Manufacturers Association Radiology Information System Open Systems Interconnection Picture Archive & Communication System Protocol Data Unit 01_05DICOM CONFORMANCE STATEMENT PACSMAIL V01.DOC 2

Images can be retrieved using a DICOM Move request Functional Definition of Listen The user can set PACSMail to manually listen for incoming DICOM Images. transferred via the C-store method with PACSMail acting as a SCP. Images are Function Definition of Auto Send This is a Windows service that can be configured to auto route DICOM Images to a remote AET. This does not require user intervention. Logs are updated where applicable Functional Definition of Auto Listen This is a Windows service that can be configured to permanently listen for incoming DICOM images to a particular port.

18 4 Communication Profiles 3.1. Supported Communications Stacks (Part 8) PACSMail V2.0 provides DICOM V3.0 TCP/IP Network Communication Support as defined in PS TCP/IP Stack PACSMail V2.0 inherits its TCP/IP stack from the Windows system upon which it executes Physical Media Support Not Applicable. 5 Extensions/Specializations/Privatizations No Extensions, Specializations or Privatizations are used. 6 Configuration PACSMail client application is configured via the address book wizard. This allows the user to configure DICOM connections with the following parameters: PACSMail AE Title IP Address Port Number Remote AET AE Title IP Address Port Number PACSMail Services are configured via configuration file. 7 Support of Extended Character Sets PACSMail does not itself use any extended character sets, but stores and passes any received through unchanged.
