Abstract
Tissue harmonic imaging, an essential mode of ultrasound imaging scanners, can provide images with high spatial and contrast resolutions. However, it is difficult to use this imaging mode in intravascular ultrasound (IVUS) imaging. This is so because typical IVUS transducers are operated at high frequency (>20 MHz) and have a narrow fractional bandwidth (about 50%). Due to its small aperture (about 0.5 mm in diameter), additionally, the strength of signal obtained with an IVUS transducer is relatively weak. For these reasons, it may be impractical to generate the second harmonic signal, and even if the second harmonic signal is generated, the signal strength is too weak to construct a high quality second harmonic image. To solve this problem, we designed and fabricated a multi-frequency IVUS transducer for second harmonic IVUS imaging.
