Abstract

According to an aspect of the present inventive concept there is provided a system for characterization of tissue of a subject, comprising a bioimpedance sensing arrangement, configured to sense an impedance of the tissue for forming impedance data, an optical property sensing arrangement, configured to sense an optical property of the tissue, a decision unit, configured to receive input data, process the input data to perform a characterization of the tissue, and estimate a confidence value for the characterization of the tissue, wherein the input data comprises the impedance data, and a control unit, configured to determine whether the confidence value subceeds a threshold and, based on the determination that the confidence value subceeds the threshold, activate the optical property sensing arrangement for acquiring further information for characterization of the tissue. According to another aspect, there is provided a method for controlling a system for characterization of tissue of a subject.

Dependent claims

A system for characterization of tissue of a subject, the system comprising:

a bioimpedance sensing arrangement, configured to be arranged within the subject, and configured to sense an impedance of the tissue for forming impedance data;
an optical property sensing arrangement, configured to be arranged within the subject, and configured to sense an optical property of the tissue for forming optical property data;
a control unit, configured to initially initiate a first sensor measurement, wherein the control unit is configured to, in the first sensor measurement, activate a first sensing arrangement selected from the bioimpedance sensing arrangement and the optical property sensing arrangement;
and
a decision unit, configured to receive input data from the first sensing arrangement, process the input data to perform a characterization of the tissue, and estimate a confidence value for the characterization of the tissue;
wherein the control unit, is further configured to determine whether the confidence value subceeds a threshold and, based on the determination that the confidence value subceeds the threshold, initiate a second sensor measurement, wherein the control unit is configured to, in the second sensor measurement, activate a second sensing arrangement selected from the bioimpedance sensing arrangement and the optical property sensing arrangement for acquiring further information for characterization of the tissue, wherein the second sensing arrangement is non-selected in the first sensor measurement.
