9. Afterlife • About 80 graduates between 2002 – 2005 • A follow-up study in 2004 (56 graduates): • About 40 % were working in medical engineering • About 10 % were unemployed • The rest were either studying further or not in medical engineering or related jobs. • Both public (e.g. hospitals) and private (mainly Oulu-area companies) sector

10. Examples of bachelor’s theses • Image archive (PACS) design works for Oulu University Hospital • Image segmentation tool for Radiology Department • ” Workflowanalyse für telemedizinische Anwendung ” (made in Germany) • Heart rate monitor-related works • Air fighter pilot acceleration studies, related to head and neck forces during high G’s • EMG measurements and analysis-related works • And many more … 

11. Foreign exchange • A few students are taking part of the international student exchange programs every year • Teacher exchange also possible

12. R&D Center for Medical Engineering • Started 2003, funding until the end of 2006 • 2 full time research positions divided between 5 part-time researchers (2 PhD, 3 MSc) • 1 full time laboratory engineer

13. Working model • Serves small to middle sized companies in the Oulu region • Different phases of product development • Up-to-date hardware and software • Centralized R&D and testing environment

14. Multidisciplinary network of consulting specialists • Saves money and time in the product development processes

15. In collaboration with • Oulu Polytechnic • Institute of Technology • Business School • School of Social and Health Care

16. Funding: Development • 1.1.2004 – 31.12.2006 • 480 k€ • Mainly personnel salaries and travel costs • ERDF (European Regional Development Fund) • Oulu Provincial Government • City of Oulu • Oulu Polytechnic • Private funding

17. Funding: Investments • 1.11.2003 – 31.12.2006 • 730k€ • Equipment • ERDF • Northern Osthrobotnia Employment and Economic Development Center • Oulu Polytechnic • City of Oulu • Companies • Innokas Medical Ltd. • Respecta Ltd.

18. Main areas of expertise • Biosignal measurements • Usability and ergonomics • Prototypes and testing

19. Equipment in biosignal measurements • Gaitrite: walking analysis • Technogym Runrace: running mat • Polar heart rate monitors and computers • Ergoline Ergoselect test ergometer

20. Equipment in usability and ergonomics • The Observer Video-Pro and mobile usability unit • Tobii 1750 Eye Tracker

21. Equipment in prototypes and testing • FDM Vantage – Rapid prototyping machine • BoundaryScan – Electrical circuit testing system

22. Medical engineering laboratory • Electrical workbench for testing and building measurement electronics • Usability unit • EM-shielded room

23. Usability unit

24. Tobii Eye Tracker • Can be used to determine what the user actually looks at when using a computer program or seeing a web page or video clip etc.

25. Rapid medical modeling • Based on Rapid Prototyping Technology. • The production process is controlled by 3D radiological images of the patient's anatomy • Photolitographic technique produces plastic model of the 3D image

26. Rapid medical models can be used • For surgical planning and simulation • For custom made implant design • For medical education and research • As a communication aid for patients and colleagues

27. Rapid prototyping • In co-operation with Oulu University Hospital, Department of Diagnostic Radiology and Oulu Polytechnic, Institute of Technology. • Data is converted to SLC or STL file format. • Data transter to Oulu Polytechnic where data is reformatted for modeling. • Maximum model size using SLA 250 stereolithography equipment is 250 x 250 x 250 The model is delivered in two weeks after receiving the data.

28. ONE REPETITION MAXIMUMPREDICTION FROM A SUBMAXIMAL PERFORMANCE IN WEIGHT LIFTINGManne Hannula, Jukka Jauhiainen and Sami Äijälä • An example of an ”own” research project of the RD Center • Patent pending • The use of acceleration sensors to estimate how much weight can be lifted once • Bench press and dumbbell concentration curl • 30 subjects • Mean absolute error less than 10 %
