Modeling a Dielectrophoresis-based Application to Personalize Cancer Treatment and Increase Recovery Rates
Modern bio-medicine practitioners are showing increasing interest in dielectrophoresis (DEP) because of the recent progress in the development of micro-electrodes. DEP gives you control of the trajectories of bio-particles (tumor cells, white blood cells, bio-markers, etc.), resulting in efficient separation and/or selective trapping with low particle damage.
View this on-demand webinar and learn how using ANSYS simulation as a virtual prototyping tool can shorten the path to commercialization of this technology and make it more robust and repeatable. We will demonstrate how to explore and optimize electrode design and operating conditions to adapt them to the specific properties of bio-particles.
Preventing Surgical Site Infections in Modern Operating Rooms
“The solution to pollution is dilution” has long been the standard philosophy when it comes to cleanroom applications of HVAC equipment. However, preventing surgical site infections (SSIs) in modern operating rooms is often associated with ensuring laminar downwash of air over the patient on the operating table. While some research indicates that laminar flow is indeed the answer, other works contraindicate this finding, concluding that laminar airflows are no more or less effective than dilution methods in preventing SSIs. Using ANSYS CFD, Nortek Air Solutions has been able to demonstrate that their Cleansuite products meet both laminar downwash and dilution design requirements, ensuring that operating rooms fitted with Nortek cleanroom products are as safe as possible for patients.
View this webinar and learn how computational fluid dynamics (CFD) can help to optimize airflow in the operating room and prevent surgical site infections (SSIs). Concrete examples as well as the benefits of this innovative modeling approach will be discussed.
In-silico Modeling of the Patient-specific Heart
The predictive modeling of cardiac mechanics to accurately reproduce the heart’s functionality and response to external disturbances remains a challenging task. The need to assess multiple physical domains — structural mechanics, fluid dynamics and electrophysiology — places high demands on numerical solution strategies.
We will present a high-resolution, 3-D, nonlinear finite element model of patient-specific heart geometries and function. The model includes an active material law prescribing the ventricular contraction along a generic muscle fiber orientation and a passive component that captures the highly anisotropic nonlinear behavior of the myocardium.
By coupling the structural model with the ventricular blood compartments, which act as zero-dimensional fluid representations of the cardiovascular system, we can model venous return by assuring conservation of volume within the closed loop circulatory system. The resulting monolithic, multifield system of equations, provides a physiologically meaningful solution of heart contraction mechanics for in silico modeling of medical device and novel disease treatment.
Computational-based MRI Thermal Injury Risk Assessment for Patients implanted with Passive Spinal Devices
Using computational modeling and simulation (CM&S) to generate evidence that a medical device meets regulatory standards is evolving quite rapidly. Regulatory agencies such as the FDA are increasingly accepting simulation data as part of the approval process. In this webinar, we will address the use of CM&S to assess the safety of patients with implanted passive devices who must undergo MRI scanning. The goal is to answer the question, “Will radio-frequency field interaction with the implanted device induce unsafe high temperatures in the surrounding tissues?”
View this webinar to learn more about the role of CM&S as a tool in generating evidence for MR device safety. The speaker will also cover important topics such as worst-case selection methodology and computational model verification, validation and uncertainty quantification.

Implementing a Microstructure-enhanced Material Model using ANSYS USERMAT for the Prediction of Bone Failure
Continuum FE models of bones and bone-implant configurations have become a standard tool to estimate bone strength. These models are usually based on clinical CT scans. In virtually all of these models, material properties assigned to the bone elements are chosen as isotropic with a stiffness based only on the density distribution. It has been shown, however, that trabecular bone can be highly anisotropic and it shows elastic plastic damage mechanical behaviour with softening.
