RISRadio-Frequency Ablation in a Realistic Reconstructed Hepatic Tissue
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study uses a reconstructed vascular geometry to evaluate the thermal response of tissue during a three-dimensional radiofrequency (rf) tumor ablation. MRI images of a sectioned liver tissue ...
HIFU Lesion Volume as a Function of Sonication Time, as Determined by MRI, Histology, and Computations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Characterization of high-intensity focused ultrasound (HIFU) systems using ex vivo tissues is an important part of the preclinical testing for new HIFU devices. In ex vivo characterization, the ...
Reduction of Noise From MR Thermometry Measurements During HIFU Characterization Procedures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Magnetic resonance (MR) thermometry is a valuable method for characterizing thermal fields generated by high intensity focused ultrasound (HIFU) transducers in tissue phantoms and excised tissues. ...
Multilaboratory Particle Image Velocimetry Analysis of the FDA Benchmark Nozzle Model to Support Validation of Computational Fluid Dynamics Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study is part of a FDA-sponsored project to evaluate the use and limitations of computational fluid dynamics (CFD) in assessing blood flow parameters related to medical device safety. In ...
