Abstract
Disclosed are systems and methods for ultrasound-and-bioimpedance-based guidance of medical devices. A system can include an ultrasound probe, a needle, a console, and a display screen. The ultrasound probe is configured to emit ultrasound pulses and receive reflected ultrasound pulses reflected back through one or more tissues for producing ultrasound images. The needle can be configured to emit, detect, or alternately emit and detect electrical currents passed through the one-or-more tissues disposed between a pair or more of system electrodes for measuring bioimpedance. The console can be configured to instantiate one or more console processes for the ultrasound-and-bioimpedance-based guidance with the ultrasound probe and the needle. The display screen is configured to display a graphical representation of the needle among anatomical features of the patient in the ultrasound images confirmed by the bioimpedance of the one-or-more tissues previously or instantly disposed between the pair-or-more of system electrodes.
