Finite Element modelling of ultrasound propagation

Searching the literature (for at least the past year), I was suprised at finding only a limited number of papers dealing with Finite Element modelling of ultrasound propagation (through solid media). These include "Modelling elastic wave propagation in waveguides with the FEM", F. Moser et al., NDT&E Int., vol. 32, 1999, "FE modelling of ultrasound...", R. Hill et al., Ultrasonics, 2004 (online) and a couple of additional papers. (There are some additional works using the finite differences method (utilizing the WAVE 2000 software) in 2D models).These FE papers claim that they came up with very promising results.

I am a little confused because I want to work in this area using FE in 3D models. My questions are:
a) does anyone know if there are some reasons for not employing FE to simulate ultrasound propagation (e.g. inability of FE to model such problems, more disadvantages than advantages. etc.)?
b) are there more papers in the literature than I have found?
c) ultrasound excitation (in contactapplication) should be regarded as a force boundary condition or prescribed displacement at the transducer/medium interface (my opinion is the former case).

Thank you very much, in advance, for your feedback
