Abstract
Systems and methods disclosed herein provide for the assessment of acousto-electrical probes, such as their connections (e.g., transducer leads) and their response characteristics. An example method of determining a capacitance capability of an electrical lead for an ultrasound device includes discharging stored capacitance of the electrical lead; applying power to the electrical lead; during applying power to the electrical lead, counting clock cycles from a microprocessor; comparing a electrical lead voltage to a reference voltage; stopping counting clock cycles when the electrical lead voltage passes the reference voltage; and processing a number of counted clock cycles, in response to stopping the counting clock cycles to determine a capacitance of the electrical lead.
