| Outline of Final Research Achievements |
In this research project, we have theoretically and experimentally assessed our new tagging MRI approach with exclusively designed tag pattern which is inspired by pattern recognition theory. By considering the bright and dark regions of tagging MRI as binary code, we previously reported an approach of tagging MRI to track fine motion with accumulation of images acquisitions. We further improve the method to complete in a single acquisition by expanding the binary code into spatial domain.
We implemented spatially selective pulses in an experimental MRI system to create a two-dimensional tag pattern by which each pixel can be discriminated each other through pattern matching of neighboring nine pixels. Experimental study with moving phantom resulted in successful detection of motion pixel by pixel.
