Rib Geometry Explains Variation in Dynamic Structural Response: Potential Implications for Frontal Impact Fracture Risk.

abstract：:We propose a multifrequency energy transmission scheme for annular phased arrays in deep-body hyperthermia. The problem of frequency dependent resonance effects reported in hyperthermia phantom calibration studies, leading to skewed energy deposition patterns and unwanted energy maxima (hot spots), is addressed by com...
