HANDHELD ULTRASOUND TRANSDUCER ARRAY FOR 3D TRANSCRANIAL AND TRANSTHORACIC ULTRASOUND AND ACOUSTOELECTRIC IMAGING AND RELATED MODALITIES

摘要

A two-dimensional wideband ultrasound transducer array for three or four-dimensional (volume+time) non-invasively imaging/mapping of electrical current in, for example, the brain through the skull, or the heart. The probe also has unique capabilities for three-dimensional transcranial or transthoracic pulse echo ultrasound (tissue structure, motion, bone thickness) and doppler blood flow imaging. The handheld device interfaces with an ultrasound delivery system for applications to human brain or heart imaging, ultrasound neuromodulation, and therapy. The handheld ultrasound array enables three-dimensional steering of an ultrasound beam through the human skull or chest for ultrasound, doppler, and acoustoelectric imaging and related modalities to aid in the diagnosis and treatment of brain or heart disorders.
