Electromechanical wave imaging offers a noninvasive alternative -- at the point of care -- to more invasive and costly techniques Thanks to a new study from Columbia Engineering School, doctors may now be able to diagnose in their offices non-periodic arrhythmias–noninvasively and at low cost–within a single heartbeat. Non-periodic arrhythmias include atrial and ventricular fibrillation, which are associated with severely abnormal heart rhythm that can in some cases be...

New technique offers safe and noninvasive drug delivery to the brain regions affected by diseases such as Alzheimer's, Parkinson's, ALS, epilepsy and more Columbia Engineering researchers have developed a new technique to reach neurons through the blood-brain barrier (BBB) and deliver drugs safely and noninvasively. Up until now, scientists have thought that long ultrasound pulses, which can inflict collateral damage, were required. But in this new study, the Columbia Engineering team show...

First non-invasive technique to directly map electrical activation of the heart Abnormalities in cardiac conduction, the rate at which the heart conducts electrical impulses to contract and relax, are a major cause of death and disability around the world. Researchers at Columbia Engineering School have been developing a new method, Electromechanical Wave Imaging (EWI), that is the first non-invasive technique to map the electrical activation of the heart. Based on ultrasound imaging, EWI...

Columbia University bioengineer Elisa Konofagou is making waves when it comes to researching treatments for degenerative brain disorders such as Alzheimer's and Parkinson's. These aren't just any waves; they're ultrasound waves. "Ultrasound denotes acoustic wave propagation. If you increase the intensity and pressure of these waves, you can cause biological effects on tissues," says Konofagou. With support from the National Science Foundation (NSF), Konofagou is experimenting with ultrasound...
