Introduction to the Integrated DICOM/Network (ID/Net v3.0)

Conformance Statement

Direction: 2118780

0.4 SCOPE AND FIELD OF APPLICATION

It is the intent of this document, in conjunction with the Introduction to the Integrated DICOM/Network (ID/Net v3.0) Conformance Statement, Direction: 2118780, to provide an unambiguous specification for GEMS implementations. This specification, called a Conformance Statement, includes a DICOM Conformance Statement and is necessary to ensure proper processing and interpretation of GEMS medical data exchanged using

DICOM.

 

The

GEMS Conformance

Statements

are

available to

the

public.

 

 

The

reader of

this

DICOM

Conformance

Statement

should

be

aware that

different

GEMS

devices

are capable of using different Information Object

Definitions.

For

example,

a GEMS

CT

Scanner

may

send

images

using

the

CT

 

Information

Object, MR

Information Object, Secondary Capture Object, etc.

 

 

 

 

 

 

 

 

 

Included

in this DICOM

Conformance

Statement

are

the

Module

Definitions

which

define

all

data

elements

used

by this

GEMS

implementation.

If

the

user

encounters

unspecified private data elements while parsing a GEMS

Data

Set,

the user

is

well

advised to ignore those data

elements

(per

the

DICOM

standard).

Unspecified

private

data

element

information

is

subject

to

change

without notice.

If,

however,

the

device is

acting as a "full fidelity storage device", it should retain and re-transmit all of the private data elements which are sent by GEMS devices.

IMPORTANT

REMARKS

 

 

 

 

 

 

 

 

 

The

use

of

these

DICOM

Conformance

Statements,

in

conjunction

with

the DICOM

Standards,

is

intended

to facilitate

communication

with

GE

imaging

equipment.

However,

by

itself, it

is

not

sufficient

to

ensure

that

inter-operation will be

successful.

 

The

user

(or

user's

agent)

needs

to

proceed

with caution

and address

at least four

issues:

 

 

 

 

 

 

 

 

 

 

 

 

©Integration - The integration of any device into an overall system of

 

interconnected

 

devices

goes

beyond

 

the

 

scope

of

standards

 

(DICOM),

and

of

this

introduction

 

and

associated

DICOM

 

Conformance

 

Statements

when_

interoperability

 

with

non-GE

 

equipment is desired. The responsibility

 

to

analyze

the

applications

 

requirements and to design a solution

that

integrates

 

GE

imaging

 

equipment

with

non-GE systems is

the

user's

responsibility

and

 

should

not

be

underestimated.

The

user

is

strongly

advised

to

 

ensure

that

such an

integration analysis

is

correctly performed.

the

range

of

interactions

 

between

any

 

GE

device

for

 

their

connection

with

GE

 

devices.

This

 

includes

the

accuracy

of

the image data once it

has

 

crossed

the

interface

between

the GE

imaging

equipment

and

the

 

non-GE device and non-GE devices,

 

before

the

connection

is

 

declared operational, should not be overlooked. Therefore,

the user

 

should

ensure

that

any

 

non—GE

provider

accepts

full

responsibility

for

 

all validation and the stability of the image

 

data

for

 

the

intended

 

applications.

Future

Evolution

-

GE

understands

 

that

the

DICOM

Standard

will

 

 

 

 

 

 

 

evolve

to

meet

the user's growing requirements. GE is actively

 

 

 

 

 

 

 

involved

in

the

development

of

 

the

 

DICOM Standard.

DICOM

will

 

 

 

 

 

 

 

incorporate

new

features and technologies and GE may follow the

 

 

 

 

 

 

 

evolution

of

the

Standard.

The

GEMS

 

protocol

is

based

on

DICOM

 

 

 

 

 

 

 

as

specified

 

in

each

DICOM

Conformance

Statement.

Evolution

of

 

 

 

 

 

 

 

the

Standard

 

may require changes to devices,

 

 

which

have

 

 

 

 

 

 

 

implemented

 

DICOM.

In addition, GE reserves the

right

to

 

 

 

 

 

 

 

discontinue or make changes to the support of communications

 

 

 

 

 

 

 

features

(on

 

its products) reflected on by these DICOM

 

 

 

 

 

 

 

Conformance

Statements.

The

 

user

 

should

ensure

 

that any

non—

 

 

 

 

 

 

 

GE

provider,

 

which

 

connects with

GE

devices,

also

plans

for

the

 

 

 

 

 

 

 

future

evolution

of

the

DICOM

Standard.

Failure

to

do

so

will

likely

 

 

 

 

 

 

 

result in the loss of function

and/or

 

connectivity

the

DICOM

is the Application data flow

diagram for the implementation model.

This

 

diagram represents the Application Entities present

in

this

implementation

and

 

 

 

graphically

 

depicts

the

relationship

of

the AE’s to real world

 

activities.

 

 

 

 

 

 

When

the

user has selected a single image or a sequence

 

of images (CINE loop) for

 

storage,

the

storage

AE

initiates

an

association with

the

storage

device.

After

verifying

the

device

is on-line, the AE

will

send

the

image

or

CINE

loop

selected

to the

device.

 

The association is then closed.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

When

the

user

selects Query RIS, the

Query

AE

opens

an

 

association

with

a

specified

server

and

 

issues a C-FIND

Request.

The

request

contains

keys

which

may

be

set

by

the

user.

 

The C-FIND responses received are displayed by

patient name.

The

user

 

may

then

select

one

of

the

patients

to

be entered

into

the

Patient

Information

screen

of

the x-ray device.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

When

the

user

 

has

selected

one

or

more

single

images

to

print,

the

Printer

AE

initiates

an association with the printing device.

After

verifying

that

the

device

is

on-line

and

 

ready to

print,

the

AE

will send the appropriate

number

 

of

images to the device for

 

printing

 

until

all

 

of

the

selected images

are

printed.

The

association

will

then

be

closed.
