| Outline of Final Research Achievements |
The performance of ultrasonic diagnostic equipment is rapidly improving owing to recent innovative developments of ultrasound-related devices. On the other hand, portable equipment is demanded for remote or emergency medical care. A current portable ultrasound system equips only one ultrasonic probe for portability. Therefore, it is necessary to use low-frequency ultrasound to image both superficial and deep organs using a single ultrasonic probe. However, low-frequency ultrasound is not preferable for imaging of superficial organs. In this study, an ultrasonic transducer, which oscillated at two frequencies (fundamental and harmonic), was developed. Also, ultrasound imaging using the developed ultrasonic transducer was conducted.
