Optimizing Dialyzer Design Using Multiphysics Simulation
A while back, I had the opportunity to speak with Steven Conrad, a critical care physician at the Louisiana State University (LSU) Health Science Center in New Orleans. Not only is Dr. Conrad a physician as well as a professor at LSU, he’s also a biomedical engineer who uses finite element analysis (FEA) to conduct research on the design of dialyzers. Dr. Conrad uses COMSOL Multiphysics to gain a deeper understanding of the physics behind these devices, and to create […]
Modeling an Accurate Drug Delivery Device
There are many different routes through which drugs and other medications can be delivered into a patient’s body during treatment. These include topographical ointments, pills, vaporizers, and injection systems, among others. Many of these drug delivery systems require an enormous amount of precision when it comes to the location, timing, concentration, and amount of the drug to be administered. This is where simulation can be a big help, as it can allow for the modeling of each of these aspects […]
Equation-Based Modeling, a Custom Model of a Beating Heart
Equation-based modeling is one of the great strengths of COMSOL Multiphysics. The ability for you to easily access the equations describing the physics you are working with, and adding or manipulating them as you see fit, dramatically opens up the realm of possibilities that you can achieve through modeling and simulation. This is exemplified by the following custom model of a beating heart.
Gold Nanorods for Medical Treatment
Nanorods are synthetic nanoscale objects used in the area of nanotechnology. They can be synthesized from semiconducting materials or metals, such as gold. The applications of nanorods are many, ranging from display technologies and energy harvesting to cancer therapy.
Improving Ultrasound Imaging Systems by Directing Sound Waves
In an earlier blog post, I commented on how acoustic waves are being used in a biomedical setting, to identify malaria in small fluid samples. A more traditional use of piezoelectric devices was written about in the latest COMSOL News. Here, an Italian company, Esaote S.p.A., uses them to produce improved ultrasound imaging systems.
