title = "Notice of Removal: Coded excitation with optimized inverse filter for improving sensitivity in acoustoelectric imaging",
abstract = "Noninvasive imaging of physiologic currents in the body is limited by poor spatial resolution due to the ambiguous conductivity distribution between the current sources and recording electrodes. Acoustoelectric imaging (AEI), based on the interaction between pressure and resistivity, provides higher spatial resolution. Although we have demonstrated AEI of the cardiac activation wave in the live rabbit heart, weak physiologic currents (e.g., in the heart or brain < 1 μV) and ultrasound (US) pulses of balanced shape (zero mean) make detection especially challenging. This study investigates the use of standard US transducers with coded excitation with optimized inverse filter to produce quasi-unipolar pulses that amplify the AE signal.",
