Cause and Amelioration of MRI-Induced Heating Through Medical Implant Lead Wires
(2014)The RF fields present in magnetic resonance imaging (MRI) scanners can induce hazardous heating in patients wearing medical implants. The inherent design and locale of deep brain stimulators (DBS) and spinal cord stimulators ... -
Electromagnetic Techniques to Minimize the Risk of Hazardous Local Heating around Medical Implant Electrodes during MRI Scanning
(2015)Magnetic Resonance Imaging (MRI) scans are contraindicated for many patients with medical implants. We establish the circumstances that cause, and the resistances required to ameliorate and to eliminate dangerous levels ... -
Implant Conductor assembly with improved Radio Frequency properties
(2017)In one aspect the invention provides an implant conductor lead assembly which includes an electrode lead, and at least one field target conductor. The field target conductor(s) is located adjacent to the electrode lead to ... -
Implantable electrode structures and their RF effects in MRI machines
(The University of Waikato, 2019)Medical implants incorporating long insulated conductors can generate a serious heating hazard to a patient undergoing a Magnetic Resonance Imaging (MRI) scan. Under the high-power RF field from an MRI machine, the conductors ... -
Impulse TDR and its Application to Characterisation of Antennas
(University of Waikato, 2011)Passive microwave systems are traditionally characterised in the frequency-domain with a vector network analyser (VNA). The measurement of antennas typically takes place in an anechoic chamber where the interference from ...
