Targeted energy transmission method using one or more ultrasonic transducers on an implantable device

Abstract

A targeted energy transmission method using an ultrasonic transducer array (101,102) on an implantable device (131) is disclosed. The method includes generating a first ultrasonic wave having at least one frequency and at least one amplitude by at least one ultrasonic transducer (111), transmitting the first ultrasonic wave to the implantable device (131), transmitting an echo signal from the implantable device (131) back to the ultrasonic transducer array (101,102), picking up the echo signal by the ultrasonic transducer array (101,102) such that the one or more ultrasonic transducers (111) acquire a plurality of received signals, coupling the received signals to a processor for generating time reversed signals; and modulating the one or more ultrasonic transducers (111) to generate time reversed waves according to the time reversed signals for transmitting the ultrasonic energy to the implantable device (131), wherein the time reversed waves undergo constructive interference at a location where the echo signal is transmitted from. 公开了一种在可植入装置(131)上使用超声换能器阵列(101，102)的瞄准能量传输方法。该方法包括由至少一个超声换能器(111)产生具有至少一个频率和至少一个幅度的第一超声波，将第一超声波传输到可植入装置(131)，将回波信号从可植入装置(131)传输回超声换能器阵列(101，102)，由超声换能器阵列(101，102)拾取回波信号，使得一个或多个超声换能器(111)获取多个接收的信号，并将接收的信号耦合到处理器以产生时间反演信号；以及调制一个或多个超声换能器(111)以根据时间反演信号产生时间反演波，以将超声能量传输到可植入装置(131)，其中，时间反演波在回波信号从其被传输的位置经历相长干涉。
