| Outline of Final Research Achievements |
In the present study, investigations were made for the realization of the abdominal cross sectional elastic property tomographic imaging based on the observations of ultrasound time of flight data around human abdominal body surface. That is to say, visceral fat and abdominal muscle distribution can be visualized from the reconstructed abdominal cross sectional sound speed image. For that purpose, a real-time body surface contour detection and automatic tracking mechanism were introduced through the laser distance sensing from three different directions. The actuators were controlled to move to the exact position with 0.1mm positioning accuracy regardless of the body motion in the middle of the measurement. Finally, investigations were made regarding the deteriorations caused by the intestinal gas or transmission through the spine. As a result, validity of the present abdominal sectional elastic composition imaging method was demonstrated.
