Patent number: 11543377Abstract: A probe comprises a resistive element configured to be brought into thermal contact with an entity to be sensed. A measurement system applies a plurality of heating pulses to the resistive element by driving an electrical current through the resistive in element and measures an electrical response of the resistive element to the heating pulses in order to determine information about either or both of the composition and state of the entity. The measurement system generates an output signal using the measured electrical response, wherein the output signal is generated by progressively offsetting the measured electrical response such that, in the event of an average temperature of the resistive element changing between different heating pulses due to a drift in the average temperature of a portion of the entity being sensed, a variance over the plurality of heating pulses of a value of the output signal at a predetermined common reference point within each heating pulse is reduced.Type: GrantFiled: June 15, 2018Date of Patent: January 3, 2023Assignee: OXFORD UNIVERSITY INNOVATION LIMITEDInventors: Kamaljit Singh Chana, Vikram Sridhar

Patent number: 11490815Abstract: Described herein are methods and systems for extracting or determining subject motion from multi-channel electrical coupling in imaging of the subject, in particular in magnetic resonance (MR) imaging of the subject. The motion can be of a region of interest of the subject (such as an organ or specific tissue). Changes in the position of the subject and the subjects organs can be monitored by measuring how external coils, such as RF coils, couple to the subject and to one another and change the scattering of the RF coils, for example scattering of RF pulses transmitted by the coils. Changes in position influence this coupling and the scattering and can be detrimental to the quality of the imaging The present methods and systems address and overcome this problem.Type: GrantFiled: March 24, 2018Date of Patent: November 8, 2022Assignee: OXFORD UNIVERSITY INNOVATION LIMITEDInventors: Aaron Hess, Matthew Robson
