摘要

一种用于微泡造影剂的主动对比成像增强技术已经被开发出来。它采用两个声场:用于调节微气泡的激发场和用于检测微气泡的成像场。由于微泡调节，散射的一谐波信号和二谐波信号分别增加了14.5和16 dB。这项技术是独特的，可以有效地增强血液与组织的图像对比度。

Active enhancement of ultrasound contrast imaging

An active contrast imaging enhancement technique has been developed for use with microbubble contrast agents. It employs two acoustic fields: an excitation field for conditioning microbubbles and an imaging field for detecting microbubbles. Up to 14.5 and 16 dB increases (due to microbubble conditioning) in scattered first and second harmonic signals respectively were obtained. This technique is unique for effectively enhancing the blood-to-tissue image contrast.
