Abstract
A method includes receiving a measurement set comprising a plurality of measurement values generated using a plurality of electrodes distributed along an elongate structure configured to be implanted in and/or on a body portion of a recipient. The measurement set is indicative of a pose of the elongate structure relative to the body portion. The method further includes generating, in response at least in part to the measurement set, a gradient vector dataset comprising a plurality of gradient vector phase values. The method further includes generating, in response at least in part to the gradient vector dataset, an evaluation of the pose of the elongate structure relative to the body portion.
Claims33
A system comprising:
- at least one data input interface configured to receive data from a plurality of transducers of a medical device configured to be implanted on or in a recipient;
- at least one controller in operative communication with the at least one data input interface, the at least one controller configured to:
- receive a plurality of measurement values generated using the plurality of transducers of the medical device in and/or on a body portion of a recipient during implantation of the medical device;
- utilize the plurality of measurement values to generate a plurality of gradient vector phase values;
- and
- generate, in response at least in part to the plurality of gradient vector phase values, intra-operative feedback information indicative of sub-optimal conditions of a pose of the medical device during the implantation of the medical device, the sub-optimal conditions to be corrected during the implantation and in response to the intra-operative feedback information;
- at least one output interface in operative communication with the at least one controller, the at least one output interface configured to provide the intra-operative feedback information during the implantation of the medical device;
- and
- an actuator configured to manipulate the medical device in response to the intra-operative feedback information.

A method comprising:
- receiving a measurement set comprising a plurality of measurement values generated using a plurality of electrodes distributed along an elongate structure configured to be implanted in and/or on a body portion of a recipient, the measurement set indicative of a pose of the elongate structure relative to the body portion;
- generating, in response at least in part to the measurement set and using a processor, a gradient vector dataset comprising a plurality of gradient vector phase values;
- generating, in response at least in part to the plurality of gradient vector phase values of the gradient vector dataset and using the processor, intra-operative feedback information indicative of non-optimal conditions of the pose of the elongate structure relative to the body portion during implantation of the elongate structure, the non-optimal conditions to be corrected during the implantation and in response to the intra-operative feedback information by an operator performing the implantation;
- communicating, using an interface in operable communication with the processor, the intra-operative feedback information to the operator during the implantation;
- and
- responding to the intra-operative feedback information by manipulating the elongate structure to correct the sub-optimal conditions of the pose.

A method comprising:
- repeatedly, during implantation of an elongate structure into and/or on a body portion of a recipient, using a processor to:
- receive a measurement set comprising a plurality of measurement values generated using a plurality of electrodes distributed along the elongate structure, the measurement set indicative of a pose of the elongate structure relative to the body portion;
- generate a plurality of gradient vector phase values in response at least in part to the measurement set;
- and
- generate intra-operative feedback information in response at least in part to the plurality of gradient vector phase values, the intra-operative feedback information indicative of the pose of the elongate structure relative to the body portion;
- and
- when the intra-operative feedback information is indicative of non-optimal conditions of the pose of the elongate structure during the implantation, manipulating the elongate structure to avoid the non-optimal conditions.
