Systems, methods, and media for real-time spatial tracking of minimally invasive instruments and components using selective color doppler markers

Abstract

In some embodiments of the disclosed subject matter, a system for tracking a medical device using color Doppler markers is provided, the medical device can comprise an ultrasound transmitter, and a lead configured to receive a square wave signal from a waveform generator and provide the square wave signal to the ultrasound transmitter causing the ultrasound transmitter to produce acoustic signals. The system can include an ultrasound machine having a display, a transducer that emits color Doppler signals, and a processor, which can be programmed to cause the transducer to emit the color Doppler signals, cause the transducer to detect color Doppler signals generated by an interaction between the emitted color Doppler signals and the acoustic signals, and generate an ultrasound image that includes a color Doppler marker indicative of the presence of the ultrasound transmitter.
