Research Abstract |
We investigated a new method based on ultrasonic velocity change by light for imaging of functional information of living tissue. The ultrasonic velocity-change image showed the hemoglobin area in the chicken meat. This method has the possibility for detection of the blood vessels in the early stage of breast cancer. The ultrasonic velocity increases in muscle and internal organs with high percentage of water content and decreases in fat as temperature increases. It was confirmed that the ultrasonic velocity-change image displayed the fat distribution in the liver of anesthetized rabbit.
