Introduction

• Overview of Testing tools
• Developmental Tools
• Open source code
• Sample Data Set
• Useful tools

3
Mesa Tools Overview

• Purpose
• Prepare systems for the connectathon
• Tools are a benefit of participation
• Tools are later released to the public
• Coverage
• Do not cover all aspects of the TF
• Do not guarantee compliance to standard
• Provide reasonable preparation to the connectathon

4
Mesa Tools Overview

• Sources available
• Serves as an example of implementation
• Benefit for the IHE community
• Feedback of users used to improve the quality of
  the tools
• However not a commercial product

5
Mesa Tools International

• Mallinckrodt Institute of Radiology
• Radiology
• IT-Infrastructure
• Cardiology (with help from Teri Sippel ACC)

• Display Consistency Tests.

6
Mesa Tools International

• NIST National Institute of Standards and
  Technology (USA)
• XDS Toolkit
• University of Quebec
• XDS-I toolkit
• INRIA
• Laboratory tools

7
Mesa Tools Concepts

• Tests are based on actor/profile
• Testing actor OP for integration profile SWF
• Peer actors simulation
• Simulation of ADT and OF actors
• Scripts for workflow testing

8
Mesa Tools Logs

• Tools output
• Produces logs used by project manager as a proof
  of successful completion of test
• Logs to be returned to project managers for
  verification

9
MIR Mesa Tools (1/2)

• Libraries MIR Dicom Toolkit
• Dicom Libraries
• HL7 messages server
• Data sets
• Sample data set
• Scripts sets
• Workflow scenario test scripts

10
MIR Mesa Tools (2/2)

• Coverage
• Radiology Profiles (except CPI)
• Cardiology Profiles
• IT-Infrastructure (except XDS)

11
Offis Softcopy test environment

• Purpose assess whether application correctly
  implements
• the grayscale transformation chain for image
  display
• the grayscale softcopy presentation state SOP
  class
• display calibration according to the display GSDF
• Contents
• a test plan document describing tests and
  expected results,
• a set of DICOM images (secondary capture),
• a set of grayscale softcopy presentation states,
• a reference implementation of a DICOM viewer,
• a spreadsheet for evaluation of GSDF calibration.
• ca. 130 test cases (ca.100 with presentation
  state)

12
Offis Hardcopy Test Hardcopy Test Environment

• Purpose assess whether a Print SCP correctly
  implements
• Presentation LUT SOP Class,
• GSDF calibration,
• the most usual of the many layout parameters
• Contents
• a test plan document describing all tests and
  expected results,
• a reference Print Client (SCU) that supports
  Presentation LUT,
• a set of print jobs that can be transmitted to a
  DICOM,
• a spreadsheet for evaluation of GSDF calibration,
• a "softcopy" print server for visual assessment
  of Print SCUs.
• 74 test cases (transmissive and reflective media)

13
NIST XDS Toolkit

• Opensource implementation
• XDS Registry and Repository
• Remote Log Analysis Tools
• Internet available server
• Ca. 50 tests for all XDS actors

14
INRIA Lab Testing Tools

• Evaluation of HL7 messages
• HL7 message validation (http//www.ihe-europe.org
  /HL7)
• Message profiles / Valid sample messages
• Work in progress
• Validation against Lab Message profiles
• Workflow scenarii Test scripts
• Webservice

15
Future

• Gazelle
• Combined effort of North America, Europe and
  Japan
• Common Framework
• Should improve
• Installation
• Maintenance
• Interactibility
