MARKO VAUHKONEN
Professori
Teollisuusfysiikka ja -matematiikka
Vauhkosen tutkimustyö keskittyy inversio-ongelmiin niin teollisissa kuin lääketieteellisissä sovelluksissa. Erityisenä tutkimuskohteena ovat niin sanotut diffuusit tomografiamenetelmät teollisten prosessien kuvantamisessa. Näillä menetelmillä voidaan tutkia tomografisesti muun muassa putkistojen ja tankkien virtauksia sekä hyödyntää mitattua tietoa laitteiden optimoinnissa ja prosessien säädössä. Lääketieteen puolella tutkimuskohteina ovat PET, SPECT ja fMRI kuvantaminen erityisesti funktionaalisissa kuvaustilanteissa. Yhtenä merkittävänä tutkimuskohteena on liikeartefaktojen poisto kehitettyjä kuvantamisalgoritmeja hyödyntäen.
