| Outline of Final Research Achievements |
In this research, 1. Polymer MEMS ultrasonic transducer, 2. Self-shape estimation beamforming, 3. 3. Device and ultrasonic wave propagation simulation, 4. System evaluation were researched. In particular, in the development of the self-shape estimation method of 2, "Kyoku-Tan" which is a flexible transducer made by Japan Probe was used. This probe is connected with a programmable beam former (Verasonics) which can be used as ultrasonic transmission / reception / RF data acquisition system. We developed a method to evaluate the transmitted beam in situ, developed a method to estimate the self shape using it as an evaluation function. Based on these results, a patent application was filed. We also confirmed its effectiveness by phantom measurement by using the method of estimating shape by cubic polynomial.
