RSNA 2013 - ICIA24 - using IHE profiles to plan for medical imaging

Top five forces to medical imaging are defined to be:

1. Cost reduction

2. Daunting PACS migration

3. Silos of imaging sources

4. Complexity of effective image sharing

5. Leverage health IT best practices

The road to effective image sharing by implementing Vendor Neutral Archive (VNA) taking care of access consolidation. Access consolidation requirements are:

1. Integrated clinical systems

2. Portability

3. Scalable

4. Extensible

5. Content accessible

IHE profiles are there to break the vendor neutral consolidation barriers.

IHE XDS provides the profiles to allow content (vendor) neutral archive. Several profiles are defined to describe the required capabilities within an XDS affinity domain such as PIX (patient identity cross referencing) , BPPC (basic patient privacy and concent) and XUA (cross enterprise user authentication).

The XDS environment can be setup as a federated, centralized or hybrid environment.

RSNA 2012 - ISP: Informatics (Image Sharing, Management and Display)

ISP: Informatics (Image Sharing, Management and Display)

Informatics Keynote Speaker: Image Sharing

Network based sharing, probably using cloud services, is mainly the replacement of the sneaker net (CD transfer) and comes with the same challenges. One has to be careful not to use tools that are used daily like Dropbox for patient related data sharing. Standards like XDR and XDM should be used to ensure safe transfer of patient data. Cloud services have to be standards based (IHE XDS.i) as implemented in the RSNA image sharing project. The exchange is based in a money transfer system where the patient gets an eight digit code and password. With these codes the patient can access the data and grant access to healthcare providers.

The RSNA’s Image Sharing Project: Initial Challenges from the Patients’ Perspective
Yousaf Awan et al

Traditionally patients are not involved in data sharing. The push to patient centered healthcare lead to the implementation of the RSNA image sharing project where the patient has control over his/her own data. Inability to access their images was the biggest issue with the current system looking at the helpdesk calls. In general, not many problems occurred.

Outcomes of an Automated System of Importation of Outside Imaging Studies into the Radiology Information System
Jonelle Marie Petscavage et al 

Patient data from CDs is uploaded decentrally and recorded in RIS and PACS. Sending AE title is set to 'OUTSIDE CD'. The error rate was less than 1%. interesting report, check our publications by van Ooijen et al in the Journal of Digital Imaging where we demonstrated something similar quite some years ago (free fulltext available)

Introducing Intuitive Simplicity in a New Type of Browser-based Dicom-Viewer for Non-Radiologists' Daily Clinical Routine
Sebastian Bickelhaupt et al

Many users are presented with non intuitive viewers that either have too much or too little functionality. The new viewer presented by this group is based on the body regions on an anatomic picture of a human. A model of human anatomy is given with colored dots on the model where the color indicates the modality and the datasets are shown next to it. After selecting the dataset of interest the DICOM data is shown and direclt connected to a 3D anatomical atlas. They showed that the new prototype speeds up and simplifies DICOM image viewing.

Influence of Medical Display System on Productivity and Eye-strain of Radiologists
Mony Weschler et al

This group compared setups with two 3MP screens to one 6MP screen both from Barco. Factors like eyestrain are evaluated using a questionnaire. It is show by this study that 6MP provides significantly less eyestrain and higher reading speeds. Although this is only based on manual registration of findings by the radiologists on a questionnaire.

Is the end of the CD era approaching?

The distribution of patient imaging data on CDs and DVDs is commonplace in almost every hospital in developed countries. However, with the increasing demand on imaging and the increase in the amount of data generated at each acquisition, the number of CDs and DVDs is increasing dramatically and the flood of portable media is almost impossible to handle. Network based sharing over the internet using secure protocols and profiles such as XDS(i) could solve the problem. Read the story from the HIMSS by Healthcare Technology Management for more information. HIMSS: Is the end of the CD era approaching?
