| Outline of Final Research Achievements |
Purpose of this project was to evaluate the advantages of a new ultra-high resolution (1 mm or so) PET scanner with semiconductor detectors for humans.
The imaging results suggested that there were certain technical problems such as scatter correction and basic design of detectors and scanner gantry, showing the need of redesigning and reconstructing the scanner. In stead, the investigator evaluated the advantages of high resolution scanner using a scanner with relatively high resolution (2 mm or so). The results of imaging suggested a high resolution scanner is better for imaging small structures in the human body.
