An ultrasonic imaging method combining physiological signals includes: obtaining an ultrasonic image of an examination object acquired by an ultrasonic imaging system at a first time; obtaining a physiological signal of the examination object acquired by a first monitoring device at a second time, where the first time and the second time at least partially overlap; aligning the ultrasonic image and the physiological signal with time; and displaying the aligned ultrasonic image and physiological signal on a same display interface.

Ultrasound imaging method combining physiological signals and an electronic device

Embodiments of the present disclosure provide a contrast enhanced ultrasound imaging method and an ultrasound imaging device. The method may include: determining a target imaging mode from preset imaging modes in response to the first instruction, where the preset imaging modes comprise a first contrast enhanced imaging mode and a second contrast enhanced imaging mode which have different frame rate; transmitting ultrasound waves to a target object and receiving ultrasound echoes returned from the target object according to the determined target imaging mode to obtain ultrasound echo signals; and generating a contrast enhanced image according to the ultrasound echo signals. An ultrasound imaging device is also be provided.

Provided by the present invention is a cathode material for a sodium-ion battery with a coating structure and a preparation method therefor. In the present invention, an Na3V2(PO4)3/C cathode material is prepared by means of a sol-gel method. Synthesized zwitterionic polymers may be used as chelating agents and as a carbon source; the process is simple, can quickly form a gel, and the reaction time is shortened contains a zwitterionic structure which may be well dissolved with the precursor of sodium vanadium phosphate to form a stable carbon coating layer. Compared to the prior art, the cathode material for a sodium-ion battery of the present invention enhances the electrical conductivity and cycle performance of the cathode material by means of the doping of nitrogen and sulfur on carbon. At the same time, the prepared cathode material for a sodium-ion battery has sodium vacancies and maintains a stable structure during the process of sodium-ion intercalation/deintercalation.
