Access to MRI is limited for patients with DBS implants due to safety hazards, including radiofrequency heating of tissue surrounding the leads. Computational models provide an exquisite tool to explore the multi-variate problem of RF implant heating. We used a computational approach to assess RF heating around tips of bilateral DBS leads during MRI at 1.5T and 3T using realistic DBS lead models. A substantial difference was found between the SAR and temperature rise at the tip of right and l... Read more

The aim of this study was to validate geometric accuracy and in vivo reproducibility of landmark-based cephalometric measurements using high-resolution 3D Magnetic Resonance Imaging (MRI) at 3 Tesla. (…) In conclusion, this study demonstrates that accurate and reproducible 3D cephalometric analysis can be performed without exposure to ionizing radiation using MRI.Read more

Deep brain stimulation (DBS) requires accurate localization of the anatomical target structure, and the precise placement of the DBS electrode within it. Ultra-high field 7 Tesla (T) MR images can be utilized to create patient-specific anatomical 3D models of the subthalamic nuclei (STN) to enhance pre-surgical DBS targeting as well as post-surgical visualization of the DBS lead position and orientation. We validated the accuracy of the 7T imaging-based patient-specific model of the STN and m... Read more

The human head can be subjected to numerous impact loadings such as those produced by a fall or during sport activities. These accidents can result in skull fracture and in some complex cases, part of the skull may need to be replaced by a biomedical implant. Even when the skull is not damaged, such accidents can result in brain swelling treated by decompressive craniectomy. Usually, after recovery, the part of the skull that has been removed is replaced by a prosthesis. In such situations, a... Read more

Food and detergent products are composed of complex micro structures. With modern microscopic techniques we can make them visible. The microstructure greatly affects macroscopic properties such as appearance, taste, mouth feel and solubility. Making these structures visible and quantifying them is essential to the development of products with optimal product properties. A broad range of imaging techniques is used to visualize microstructure elements at different length scales. For example, X-... Read more

The CHEFF (Computational Heat Fluid Flow) Research group at Florida Agricultural & Mechanical University is using computational fluid dynamics to model flow and heat transfer in various engineering applications for industry, government and the private sector. The primary goal of this research is to first examine and then enhance the thermal performance of current and future low-density reticulated porous media, and explore their use as heat sinks in high power electronics (computer chips...
