And most papers published assume that there is no interaction between the acoustic and structure modes. This paper tries to realize how sound source affects the acoustic transmission and whether the acoustic resonance could couple with the structure. A s...

Both advances in cross-sectional image guidance and cytopathologic techniques allow TNB to accurately diagnose malignancy and characterize a spectrum of benign conditions. Image-guided percutaneous drainage of intrathoracic collections has developed as an extension of similar pr...
