| Outline of Final Research Achievements |
This study aims to devise a multi camera system that takes a stereoscopic image by shifting the vision of a gamma camera functionally (virtually) in order to improve “resolution” and “depth information,” which have been problems with conventional imaging. In addition, this study also aims to develop a method of analyzing nuclear medicine image quantitatively and to conduct research on a new imaging technique that helps to diagnose, detect and forecast disease early as well as to assess the state of disease.
The results of this study show that recognition rate using stereoscopic image was higher than using conventional image. In conventional image, perilesional area was blurred due to scattered radiation, and it was difficult to distinguish the difference in size. On the other hand, in stereoscopic image, lesion area can be easily distinguished from normal area. These findings indicate that stereoscopic image helps improve diagnostic performance.
