Voice RecognitionWhat it should
And can doFor radiology
Introducing Myself
• Malcolm Grant
• GHG Software Developments Ltd
• Working with VR in radiology > 5 years
• Installed a number of NHS VR Systems
What it Should Do
• Save time and money?
• Shorten turnaround times?
• Improve reporting quality?
• If possible deliver all 3 together!!!
What it Can Do
• Save time and money
• Shorten turnaround times
• Improve reporting quality
• So why is it not in more universal use? ….

Voice Recognition
Cultural Change?
• Authors need RIS and VR knowledge– not just PACS – therefore learning curve
• Authors take full responsibility for Report– Second language speakers, mumblers– Full proof reading burden
• Appropriate workflows– Scanned request cards, barcodes, worklists
Reputation?
• “I tied voice recognition bee 4 and it did not walk”
• This is not a demo day, but …
• The technology is proven to deliver
• What is needed to succeed?
What is Needed
• High accuracy and fast editing
• Tight integration with RIS and PACS
• Network solution
• Good ergonomics
• 1:1 training
What is NeededHigh accuracy and fast editing
• UK Radiology Vocabulary essential
• Speech Engine dependency is high– Near monopoly
• Voice friendly report box– Not evident in most RIS systems
• Can all be checked in a short demo
What is NeededTight integration with RIS and PACS
• Authoring must be time-neutral– Benefits are not directly for the Author– RIS designed for typists, not authors– Measurement is for report + verification
• RIS overheads must be minimised– E.g. “No bony injury seen”, “Heart and lungs
are clear, no abnormalities of note”
• Drive must be easy to use– Simple accurate commands, fast drive
What is NeededNetwork solution
• Speech engines designed for single users
• Radiologists need to move around
• Shortcuts need to be shared and individual
• Voice files need to be network managed
• Back-end recognition also required– E.g. Breast clinic
What is NeededGood ergonomics
• Choice of Microphone– Accuracy, portability, durability, comfort
• Foot-pedal controls (mike control)– Needed to remove mike control issues
• Focus controls– Dictation, PACS RIS (mouse free)
• True hands-free use– Keyboard to be an option only
What is Needed1:1 Training
• Trainer - Expert in VR– Every speaker is different– Broad experience needed
• Trainer – Conversant with RIS and PACS– Able to advise on best practice– Good experience in radiology
Successful implementation
• Choose an experienced specialist vendor• Check recognition accuracy, speed, editing and
shortcut capabilities at the demo stage• Sign-off an integration specification
– Detail RIS and PACS issues– Test in a pilot (e.g. 4 users)
• Roll-out in stages with full training– 2 1:1 sessions with each author (approx 6 hrs/author)– Review management issues at each stage

Users - Stated Benefits
• Faster turnaround
• Immediate verification
• Workflow improvements
• 24-7 working
• Encouragement to standardisation
• Improved user satisfaction
My stated benefits
• Verification time saved (10%)
• Large savings in typing costs
Users - Stated downsides
• Up to 50% slower reporting initially
• Users take up to 3 monthsto get up to speed
• Proof reading of long reports can be weak
• Minority of users do not succeed
