Presently several new methods are being developed to recanalize obstructed arteries during catheterization. Intra-arterial high frequency ultrasonic imaging may be used as a guidance for these new techniques. Spark erosion is a new obstruction removal technology. Experiments have shown that this method can be applied in a selective way. An ultrasonic intra-arterial imaging system allows for the proper indication of the spark erosion catheter relative to the obstruction. The first in vitro results of this study illustrate that integration of catheter tip imaging and spark erosion is possible.
目前正在开发几种新方法，用于在导管插入过程中使阻塞的动脉再通。动脉内高频超声成像可作为这些新技术的指导。火花腐蚀是一种新的阻塞清除技术。实验表明，该方法可以有选择地应用。一种超声动脉内成像系统能够正确显示火花腐蚀导管相对于阻塞物的位置。这项研究的首个体外实验结果表明，导管尖端成像与火花腐蚀相结合是可行的。
