Understanding the dynamics of microbubble oscillation in an elastic microvessel is important for the safe and effective applications of ultrasound contrast agents in imaging and therapy. Numerical simulations based on 2D finite element model are performed to investigate the effect of acoustic parameters such as pressure and frequency on the dynamic interaction of the fluid-blood-vessel system. ...
Medical imaging methods have become increasingly important in diagnosing diseases and assisting therapeutic treatment. In particular, early detection of breast cancer is considered as a critical factor in reducing the mortality rate of women. Within the various alternative breast imaging modalities being investigated to improve breast cancer detection, microwave imaging is attractive due to the...
In this paper, the most widely used and extensively validated techniques for imaging coronary artery disease are reviewed. We describe and compare the roles of echocardiography, cardiac nuclear imaging techniques and cardiac magnetic resonance imaging. For now we see through a glass, darkly. echocardiographic imaging Two-dimensional evaluation of coronary artery disease at rest Evaluation of le...
How It Works Unlike X-Ray systems with their ionizing radiation, and active Microwave systems which bathe the subject in RF, passive millimeter-wave (PMMW) imaging systems read the natural thermal energy in environment, much like an infrared camera. Unfortunately, infrared wavelengths are too short to pass through clothing, so we choose a longer wavelength of 3 millimeters (specifically 80 to 1...
