Abstract
A device for monitoring an implant comprises: an array of ultrasound transducer elements configured to receive a localization ultrasound signal from the implant; and a signal processor configured to, for each ultrasound transducer element of at least a subset of ultrasound transducer elements, identify a time point corresponding to a peak intensity of the received localization ultrasound signal at the ultrasound transducer element, wherein relative time delays between the time points identified for the ultrasound transducer elements form information relating to a location of the implant.
Claims13
A device for monitoring an implant;
- said device comprising:
- an array of ultrasound transducer elements configured to receive a localization ultrasound signal from the implant and transmit powering ultrasound signals towards the implant for powering the implant;
- a signal processor configured to, for each ultrasound transducer element of at least a subset of ultrasound transducer elements, identify a time point corresponding to a peak intensity of the received localization ultrasound signal at the ultrasound transducer element, wherein relative time delays between the time points identified for the ultrasound transducer elements form information relating to a location of the implant, and
- wherein the subset of ultrasound transducer elements is further configured to transmit the powering ultrasound signals towards the implant for powering the implant, with relative output delays, wherein the relative output delays are reversed in relation to the relative time delays.
A method for monitoring an implant, said method comprising:
- receiving a localization ultrasound signal from an implant using at least a subset of an array of ultrasound transducer elements;
- for each ultrasound transducer element in the subset, identifying a time point corresponding to a peak intensity of the received localization ultrasound signal at the ultrasound transducer element, wherein relative time delays between the time points identified for the ultrasound transducer elements form information relating to a location of the implant;
- and
- transmitting, by the ultrasound transducer elements in the subset, powering ultrasound signals towards the implant for powering the implant, wherein powering ultrasound signals of the ultrasound transducer elements are output with relative output delays, wherein the relative output delays are reversed in relation to the relative time delays.
