A Feasible Method to Evaluate RF-Induced Heating Behavior of Passive Orthopedic Implants in Human Body
… imaging (MRI) radio frequency (RF) -induced heating is one of the most important concerns of MRI safety for patients with implantable medical devices. Due to the difficulties of performing direct study of the RF-induced heating in human body for an implantable medical device, the current …

Comprehensive MRI Safety Assessment: Impact of Strain-Relief Loop Position, Lateral Movement, and Varying Field Strengths on RF-Induced Heating of Medical Implants
… on three factors critical to the RF-induced heating hazards of implantable medical devices (IMDs). First, the impact of strain relief loop positions on RF heating of AIMDs at 1.5T MRI is studied. The AIMDs are constructed with an implantable pulse generator (IPG) and insulated leads with …

Microfabrication of surface electrode ion traps for quantum manipulation
… decoherence is dominated by the uncontrolled heating of ion motional states. In this thesis, we present the detailed microfabrication of several series of surface electrode linear Paul traps made from different electrode materials, followed by the ion motional heating experiment results for …

Methods and Strategies for Evaluating MRI Rf-Induced Heating for Implanted Metallic Stents
… devices, and radio frequency (RF)-induced heating is one of the major concerns. As one of the general metallic implanted devices, however stents are not fully studied on its RF-induced heating behavior. In this work, evaluations of MRI RF-induced heating are carried out on implanted medical …

Effect of Fat Content and Food Type on Heat Transfer during Microwave Heating
… in less time. However, due to non-uniform heating nature of microwave cooking, there exists a serious concern over complete elimination of pathogens in the food. There has been an increase in interest to accurately understand the behavior of different food materials in a microwave field and …

Prediction and mitigation strategies for the transient thermal performance of low thermal resistance microchannel evaporators
… performance of the device under steady state heating conditions. These overshoots were exacerbated with higher heating rates and reduced subcooling but were generally improved with higher flow rates. Applying a slower heating rate greatly improved the transient thermal response, reducing both …
