Experience : the power of precedent

• Experience = I’ve seen this problem before (or one like it)

• I’ll base what I do on what I did the last time …

• That assumes I can find what I did the last time!

The solution : a new kind of search

• Search freely –unconstrained ‘Google’ like searches

• Recall effectively –visualise a previous treatment scenario and transpose it to the one in front of me

The solution : a new kind of search

• No overhead – automate the data capture from DICOM

• Platform agnostic – work with data from any source

• Ubiquitous

REPURPOSING KNOWLEDGE FROM GRID COMPUTING

Page 9: Accel-RT · Accel-RT Implementation A Ethical framework for collection of patient image data er Collect data objects, anonymise and process for research DB abase Web based database,

Grid Computing

• Astrophysics : 100Gb data per night sky

• Particle Physics and LHC : 10% of global internet bandwidth consumed during experiments

• Distribute compute and storage across the world

Changing landscape of our RT data•2008

– Paper action sheets & prescriptions

– No templates

– Limited IMRT use cases

Accel-RT | COMPRT Symposium | Cavendish Laboratory | 17th June 2015

•2014– Paperless OIS

– Extensive templating

– Extensive IMRT and IGRT

AIDA & DICOM Push

• AIDA = Anonymous Image Donation Archive

– REC approved NHS research DB

– Allows multiple usage, prospective and retrospective capture of images

• ToAida DICOM node on physics network

Object packager

• Ingest DICOM images, DICOM RT files, planning annotations

• Anonymise data and create unique study identifiers

• Compress data to single file for upload

LESSONS LEARNED FROM COLLABORATION

Page 24: Accel-RT · Accel-RT Implementation A Ethical framework for collection of patient image data er Collect data objects, anonymise and process for research DB abase Web based database,

• Great questions!

• Challenge conventional ways of thinking

• You don’t know what you don’t know

Encompassing change

• Research partnerships changed to reflect changing business and research priorities

• Opportunities to work with new industry partners (OSL UK)

• New clinical workflows

• New hardware & software technologies

What next?

• Few things to finish up!

• Ramp up data flows and use system in the workplace

• See Accel-RT used at a national level (clinical trials?)

• Accel-RT 2 – link the data warehouse to a simulation engine
