Abstract: Provided is a method for preparing copper azide and cuprous azide encapsulated by conductive metal-organic framework. The method uses a conductive copper-containing metal-organic framework material as a precursor, and completes the azidation of the precursor by means of a liquid-solid electrochemical azidation reaction. Copper azide and cuprous azide nanocrystals are highly uniformly embedded within a conductive framework, which may effectively avoid the agglomeration of copper azide and cuprous azide, and reduce static charge generated by friction, displacement, and the like. Meanwhile, the conductive framework may promote the effective transfer of charge, avoid the accumulation of static charge, and improve the electrostatic safety.

An ultrasound transducer array is positioned adjacent a tissue of the subject to which the electrotherapy treatment is to be applied. The electrotherapy treatment is administered to the tissue as a plurality of ultra-short electric pulses which generate an electric field in the vicinity of the tissue. The ultrasound transducer array detects acoustic signals which are induced by the electric field. The detected acoustic signals are then used to construct tomographic images which represent the electric field generated by the electrotherapy treatment during real-time.
