MRI COMPATIBLE 3-D INTRACARDIAC ECHOGRAPHY CATHETER AND SYSTEM

摘要

Intracardiac imaging system carrys out conduit with internal capacity with intracardiac ultrasound, proximally and distally endurance, the conduit includes the distal end that conduit is arranged in atraumatic tip, a pair of coil inductively is close to atraumatic tip, it is provided with a pair of of coil between the image chip of CMOS volumes at least one CMUT, be arranged in the volume of cable lumen and is configured with a small amount of electrical connection due on the CMUT CMOS chips that are largely multiplexed. Conduit can be by MRI compatible materials and may include active cooling access. The element for having multiple Tx on the CMUT CMOS chips sends image pulse, and multiple receiver units are set to the element that the chip is formed with large aperture and multiple electrical interfaces and Tx and Rx beam of unit, to generate radio frequency output signal.
