英文摘要	Micro-ultrasound (micro-US), also known as ultrasound biomicroscope, is able to delineate small structures with fine spatial resolution. However, micro-US suffers limited depth of penetration due to significantly large attenuation at high frequencies. Modulated excitation imaging has displayed the capability to improve the penetration depth, while maintaining the spatial resolution. But the effectiveness of this technique in micro-US has not been fully demonstrated. This paper presents the development of a novel system to achieve modulated excitation imaging with high programmability and flexibility to satisfy various micro-US studies. Test results show that the proposed modulated excitation imaging system can acquire up to 20 dB signal-to-noise ratio improvement and 83% increase of penetration depth in contrast to traditional short-pulse imaging method. In vivo experiment on the dorsal skin of a human hand demonstrates good performance of the programmable modulated excitation imaging system.
