Patent ID: 8764662

Claim:
An ultrasound imaging system comprising: at least one ultrasound probe, wherein the ultrasound probe comprises at least one ultrasound transducer and a plurality of application specific integrated circuits; one or more temperature sensing devices disposed on at least one of the plurality of application specific integrated circuits such that the temperature sensing devices are in thermal contact with one or more heat producing regions of the ultrasound probe; and at least one calibration circuit coupled with the one or more temperature sensing devices, the calibration circuit comprising: a voltage amplifier; a reference voltage generator configured to provide reference voltage input to the voltage amplifier, wherein the reference voltage input corresponds to voltage expected to be generated by the temperature sensing device in response to temperature of a predefined value; a switch configured to couple either the one or more temperature sensing devices or the reference voltage generator with the voltage amplifier; and a digital-to-analog converter configured to provide a correction signal to the voltage amplifier based on an error between an output generated by the voltage amplifier for the reference voltage input and output generated by the voltage amplifier for an output of the one or more temperature sensing devices in response to the temperature of the predefined value.
