Profiles for Imaging Media Exchange
IHE two core profiles for Imaging media exchange
Portable Data for Imaging (PDI) Standardize CD media
Import Reconciliation Workflow Fix demographics, IDs and codes
Now include:
Portable Data for Imaging (PDI) – Extensions New media(DVD & USB), Compression & Security
IHE Basic Image Review (BIR) Profile Baseline behavior for viewer software

Portable Data for Imaging (PDI)
www.ihe.net
Compatibility requirements
Standard CD format and file system
Consistent disc organization
Use most generic DICOM media profile
Images MUST be present in DICOMo May have copies as “web content” (i.e. JPEGs)
Avoid most common mistakes (highlighted)
Portable Data for Imaging (PDI)
www.ihe.net
Additional Media:
Compression Optionally allowed
• Both Lossless and lossy specified; but lossless is recommended
On-board “Sender Software” recommended.
Encryption Optionally allowed; password-based or key-based Please consider support needs before creating
DVD
PDI –Extensions
www.ihe.net
1) Insert CD; Run Sending Software
2) “Enter Password:”
5) DICOM Association Negotiation
7) Send Images (C-STORE)
4) “Enter Destination:”3) Sending Software Decrypts CD Images
6) Sending Software decompresses & convertsImages (as needed)
PDI –Extensions

New Media type OptionsBaseline Media: CD
DICOM STD-GEN-CD Media Application Profile
New Media Options:
DVD Option • Creator Uses DICOM STD-GEN-DVD-JPEG or
• DICOM STD-GEN-DVD-J2K Media Application Profile*
USB Option • Creator UsesDICON STD-GEN-USB-JPEG or
• DICON STD-GEN-USB-J2K Media Application Profile*
Both options require support for compression
JPEG lossy and lossless
JPEG 2000 reversible and irreversible
NOTE: DVD option will allow for CD Compression
* Importer must support both Media Application Profiles
www.ihe.net
Privacy Protection Options
Privacy Protection Options
Standard Password-Based Encryption (PBE) RSA Public Key Infrastructure (PKI)
Use the secure DICOM Media Application Profiles
STD-GEN-SEC-CD for CD STD-GEN-SEC-DVD-JPEG or STD-GEN-SEC-DVD-J2K for DVD STD-GEN-SEC-USB-JPEG or STD-GEN-SEC-USB-J2K for USB
Options require encryption of all DICOM files
including the DICOMDIR, and any files with Patient identifiable information
Note: Options NOT compatible with the Web Option
Media supplied viewers or sending SW must be capable of requesting
password (PBE option) or use the RSA private key (PKI Option)
www.ihe.net
Portable Media Sender Option
Required when disk is encrypted (Privacy Protection Option)
Only required to be capable of decryption if encrypted
decrease risk of unreadable data by recipient
Transfers objects on the media
to an Image Manager and/or Report Manager
Reconciles key patient and study attributes
Decompresses instances if necessary
Decrypts instances if necessary
Required to convert multi-frame to single frame if necessary
www.ihe.net
Import Reconciliation Workflow (IRWF)
www.ihe.net
“The Images are in the PACS but are messed up” The patient ID is wrong, it doesn’t come up in a query I can’t hang the new images with the old The unknown procedure codes mess up my hanging protocols The images aren’t linking to the EMR.
Patient’s chart won’t come up
Impact: Lost time Incomplete data Drags on effectiveness
Import Reconciliation Workflow – Value Statement
www.ihe.net
During image import, details are fixed to match (or not conflict with) local values Patient IDs, Name Procedure Codes, Accession Numbers, etc.
Two ways of getting demographics DICOM Worklist Query HL7 Patient Demographics Query

“Advanced” Button = Show me what else you can do

Basic Image Review (BIR)
www.ihe.net
Basic Image Review ( BIR) - Value Statement
www.ihe.net
Facilities distribute images; Physicians review them Often a physician has own viewer but may need to rely on the media-
supplied veiwer
Rising frustration; too often the viewer: requires installation on a locked down machine does not successfully run starts up too slowly does not successfully load the images warns the images are of “non-diagnostic quality” is missing some basic critical function has Yet Another GUI where basic operations are non-obvious
Impact: delayed care, inaccessible information, repeat examination and irradiation,
and poor use of valuable clinician time.
Basic Image Review (BIR) – Value Statement

Trial Implementation Spec released
Potential applications of BIR Spec. Media Viewer (PDI Option)
o Requires a BIR Compliant viewer be placed on media Clinician’s Desktop Viewer Basic Radiology Review Station Web Portal

SOP Class Support
Notes: PDI Basic Viewer Option - requires only SOP Class support on media
non-PDI requires a partial display requirement for SOP classes not listed
