Abstract :
Noninvasive treatment of solid tumors with MR guided focused ultrasound surgery (MRgFUS) requires a fast and reliable technique for temperature measurement. The goal of the work described in this paper was to investigate a post-processing method to enhance MRI temperature measurements. Data sets similar to MRI measurements were artificially created and afterward enhanced. As a result a much better temperature prediction was achieved and a higher spatial resolution was obtained.
