RISA Novel Finite Element Model to Assess the Effect of Solid Stress Inside Tumors on Elastographic Normal Strains and Fluid Pressure
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Ultrasound elastography is a noninvasive imaging modality used to assess the mechanical behavior of tissues, including cancers. Analytical and finite element (FE) models are useful and effective tools to understand the ...
Modeling Decision Support System for Optimal Disease Diagnosis and Treatment of Cerebral Aneurysm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a novel decision support system (DSS) to assist medics administer optimal clinical diagnosis and effective healthcare post-treatment solutions. The DSS model that evolved from the research work predicted ...
A Computationally Efficient Computer-Aided Design Strategy for Iterative Combat Helmet Design and Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Assessing combat helmet ballistic performance is a costly endeavor using either an experimental or a computational process. Experimental assessment requires many iterations and helmets to acquire a sufficient data set. To ...
The Role of Airway Shunt Elastance on the Compartmentalization of Respiratory System Impedance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An inverse model consisting of two elastic compartments connected in series and served by two airway conduits has recently been fit to measurements of respiratory impedance in obese subjects. Increases in the resistance ...
Acoustic Signatures of Left Ventricular Assist Device Thrombosis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Left ventricular assist devices (LVADs) are life-saving, surgically implanted mechanical heart pumps used to treat patients with advanced heart failure (HF). While life-saving, LVAD support is associated with a high incidence ...
Plastic Energy Dissipation in Lumbar Spine Implants: A Contact Mechanics Point of View
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, an elastoplastic contact model is developed for L1–L5 lumbar spine implants. Roughness effect is included to estimate energy loss which is an indication of wear and subsequently the issue of metal debris in ...
Quantification of Thermal Injury to the Healthy Tissue Due to Imperfect Electrode Placements During Radiofrequency Ablation of Breast Tumor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Radiofrequency ablation (RFA) has emerged as an alternative treatment modality for treating various tumors with minimum intervention. The application of RFA in treating breast tumor is still in its infancy stage. Nevertheless, ...
Myosin Crossbridge, Contractile Unit, and the Mechanism of Contraction in Airway Smooth Muscle: A Mechanical Engineer's Perspective
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Muscle contraction is caused by the action of myosin motors within the structural confines of contractile unit arrays. When the force generated by cyclic interactions between myosin crossbridges and actin filaments is ...
Design of a Novel Electrode of Radiofrequency Ablation for Large Tumors: A Finite Element Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The aim of the study was to design a novel radiofrequency (RF) electrode for larger and rounder ablation volumes and its ability to achieve the complete ablation of liver tumors larger than 3 cm in diameter using finite ...
Level of Cutaneous Blood Flow Depression During Cryotherapy Depends on Applied Temperature: Criteria for Protocol Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cryotherapy is commonly used for the management of soft tissue injury. The dose effect of the applied cooling temperature has not been quantified previously. Six subjects were exposed during five different experiments to ...
