Comprehensive intracardiac Doppler examination under simultaneous direct ultrasound visualization has not been previously possible. This human feasibility study demonstrates that a new 10Fr, 3.2-mm diameter, 5.5- to 10-MHz frequency agile, phased, vector array, ultrasound-tipped catheter with 4-way tip articulation provides diagnostic, high-quality, intracardiac Doppler signals using pulsed and continuous-wave, color flow, and tissue Doppler.
以往无法在直接超声可视化的同时进行全面的心内多普勒检查。这项人体可行性研究表明，一种新型的10Fr、直径3.2毫米、频率在5.5至10兆赫之间可灵活切换的相控阵、带4向尖端关节的超声探头导管，能通过脉冲波、连续波、彩色血流和组织多普勒技术提供诊断性的高质量心内多普勒信号。
