1. Introduction

1.1. Purpose of this Document

This document is the DICOM Conformance Statement for the Immedia Archive and the Image

Manager Server products. The purpose of this document is to describe how these Merge eMed

servers interact with other DICOM devices on the network. In the ensuing discussion, the term

“Immedia Archive” will be used to address both devices.

1.2. Sources for this Document

NEMA) Digital Imaging and Communications v2.0, 1988.

• ACR-NEMA Digital Imaging and Communications in Medicine (DICOM) v3.0, 1993-2004.

1.4. Connectivity Advisory

The use of this Conformance Statement by itself does not guarantee successful inter-operability

of Immedia Archive with equipment from other vendors. The user or integrator should keep the

following issues in mind:

1. Successful inter-operability of Immedia Archive with other devices may require functions that

are not specified within the scope of DICOM.

2. Merge eMed offers products and services to analyze and validate DICOM connections,

including connectivity and data accuracy.

2. Implementation Model

A-DICOM V3.0 4 of 22 Archive/IM Server DICOM Conformance Statement


The Immedia Archive is a Sun based application that runs under the Solaris operating system. It

is designed to receive images from different devices, optionally compress the images using

wavelet compression techniques, then route these images to remote devices connected via LAN

or WAN.

The Immedia Archive uses DICOM services to:

• receive and transmit images

• provide remote access to the content of the server

The Immedia Archive DICOM AE behaves as a single Application Entity according to DICOM

standard. Figure 1 shows the available interfaces.

The Immedia Archive DICOM AE supports the C-Store service class as a Service Class Provider

for the purpose of storing images. Based on configuration settings, the images shall be stored in

their entirety, either unchanged, in a wavelet-compressed format, or in a JPEG 2000 compressed

format.

2.2.2. Transmit Images

The Immedia Archive DICOM AE supports the C-Store service class as a Service Class User for

the purpose of transmitting images to remote devices.

2.2.3. Query/Retrieve Server

The Immedia Archive DICOM AE supports the Query/Retrieve service class as a Service Class

Provider to allow remote devices to query and retrieve data from the local storage.

2.3. Sequencing of Real World Activities

Not applicable.

Merge eMed DICOM AE can transmit uncompressed, compressed and decompressed images.

The following elements are added/changed when the image has undergone Wavelet

compression. All elements not listed take on the original value.

A-DICOM V3.0 11 of 22 Archive/IM Server DICOM Conformance Statement


Table 6 DICOM elements modified for compressed images

DICOM Element DICOM Tag Possible Values

Image Type (0008,0008) Appends either one of the

strings below:

“Compressed :1”

“Decompressed :1”

Note: This is optional and can

be disabled.

Derivation Description (0008,2111) “Compressed :1” or

“Decompressed :1”

Lossy Image Compression (0028,2110) 01

Pixel Data (7FE0,0010) Compressed or

decompressed pixel data

Historically, the Wavelet compression techniques used by the Immedia Archive could only be

used on images containing unsigned pixel values. For modalities that contain negative pixel

values (in particular, CT images), a "pixel correction" algorithm could be applied. This algorithm

adds a constant value to all pixel values, compensating for the shift by adjusting the Rescale

Intercept (0028,1052) by the same value.

For JPEG 2000 compression, the Immedia Archive conforms to the changes required by the

DICOM standard.

3.3.2.3. SOP Specific Conformance - Storage

Merge eMed DICOM AE conforms to the DICOM Storage Service Class at Level 2 (Full) for

uncompressed images. Certain elements are coerced by Merge eMed DICOM AE for

compressed images. These elements are listed in section 3.2.2.3. Merge eMed DICOM AE

requires the Patient ID (0010,0020) to be unique. In the event of a successful C-STORE

operation, the image has been written to internal storage. Merge eMed DICOM AE returns one

of the following status codes:

defined in Part 8 of the DICOM Standard.

A-DICOM V3.0 20 of 22 Archive/IM Server DICOM Conformance Statement


4.1. TCP/IP Stack

Merge eMed DICOM AE inherits its TCP/IP stack from the computer system upon which it

executes. The Compression Server DICOM SCP services listen for DICOM connections on port

104, but this can be changed by editing the system configuration.

4.1.1. Physical Media Support

Merge eMed DICOM AE is indifferent to the physical medium over which TCP/IP executes; it

inherits the medium from the computer system upon which it executes.

5. Extensions/Specializations/Privatizations

Merge eMed SCU/SCP may implement specialized image decompression for support of certain

Teleradiology applications. See section 3.2.2.3 for details.

6. Configuration

Merge eMed DICOM AE obtains configuration information from the following sources:

• Mapping from Application Entity Title to Presentation Address is provided by the database.

• Configuration table stores Application Entity Title, default PDU size, and preferred byte

orders for the SOP classes that Merge eMed DICOM AE supports.

7. Support for Extended Character Sets

Merge eMed DICOM AE supports the following character sets:

• ISO-IR 6 (default) Basic G0 Set

• ISO-IR 100 Latin Alphabet No. 1
