1. The development & integration of a Real- Time X-Ray image transfer system over a wireless network Progress Presentation Capt David Clarke

2. Outline Of Presentation Background to Project Research of Technology Progress to date Work left to be done

3. Background to Project The Army Ordnance Corps recently upgraded their HOBO robot Using COFDM for video link Also use a manual x-ray system Reamda investigating use of COFDM to send x-ray picture wirelessly My intention is to develop a system that can transfer an image

4. Research of Technology COFDM Multi-carrier transmission technique Uses bandwidth efficiently Very robust against channel interference Uses a Guard Interval

5. Research of Technology Non-Destructive Testing Amorphous Silicon Digital Radiography Instantaneous digital readout of x-ray image Manual Deployment Image size between 5MB and 15MB Too largefor transmitting Used in vast number of industries

6. Research of Technology

7. JPEG Standardised image compression algorithm Lossy image Trade-off of file size vs image quality Mathematical formula Source code freely available

8. Progress to Date Research undertaken Delayed start Gumstix platform LINUX Simulating of COFDM channel Use of Python?

9. Work left to be done Compressing of image in Gumstix platform [finding/writing code to implement] Send via USB firstly, then using Ethernet COFDM testing ? Channel Simulation Further Milestones 7 weeks to have viable project working

10. Thank you for your attention
