Acquisition Protocol and Comparison of Myoelectric Signals of the Muscles Innervated by the Ulnar, Radial and Medial Nerves for a Hand Orthoses
This paper proposes a protocol for obtaining surface myoelectric signals in muscles of the upper limb for characterization of hand movement patterns. To characterize the movement patterns, the magnitude of the signal from ...
Mechanical Pain Assessment Through Parameters Derived from Photoplethysmographic (PPG) Signals: A Pilot Study
Based on the fact that pain modulates the contour of the photoplethysmographic (PPG) signal, several authors have used PPG-derived parameters, like the amplitude of the PPG signal (PPGA) and the variations of the inter-pulse ...
Estimation of Electrical Conductivity from Radiofrequency Hyperthermia Therapy for Cancer Treatment by Levenberg Marquardt Method
Introduction: The radiofrequency hyperthermia is a technique that by induction of the electromagnetic waves produces the heating in the biological tissues. The increase in body temperature in a range of 40 °C to 46 °C ...
Comparison of Attenuation Coefficient Estimation in High Intensity Focused Ultrasound Therapy for Cancer Treatment by Levenberg Marquardt and Gauss-Newton Methods
Hyperthermia using High-Intensity Focused Ultrasound (HIFU) is an acoustic therapy used in clinical applications to destroy malignant tumors of bone, breast, brain, kidney, pancreas, prostate, rectum and testicle. This ...
Real-time temperature estimation with enhanced spatial resolution during MR-guided hyperthermia therapy
(Taylor and Francis Ltd., 2020-04-17)
In this article, the temperature of biological tissues is estimated during hyperthermia therapy, while accounting for uncertainties in the bioheat transfer problem and in the available measurements. A state estimation ...
