| Outline of Final Research Achievements |
In order to increase the quantitative performance of ultrasonic molecular imaging, the method to estimate the number density of contrast agents was proposed and the evaluation system was constructed to verify the performance of proposed method. The transducer for pulse-echo method was incorporated into the evaluation system beased on quartz crystal microbalance for the verification. Using the evaluation system, the interaction between avidin as target molecule and biotinylated bubbles as contrast agents was monitored by pulse echo method. As a result, we succeeded in detecting the interaction by analysis of the echo signal. In addition, we developed the evaluation system into more stable one by using flow cell where the liquid was automatically sent.
