Abstract

It has been previously reported that the acoustic microscope can be used to measure changes in the elastic properties of muscle.1,2 Such changes could then be used to measure changes in cardiac contractility and other muscle properties in the fetal mouse heart organ culture model.3 The bulk modulus of elasticity of the muscle would be determined from the well-known relation
$$ {\rm{K}}\,{\rm{ = }}\,{\rm{\rho }}{{\rm{c}}^{\rm{2}}}\,\,, $$
where ρ is the tissue density and c is the velocity of sound in the muscle. Because the heart has a complex geometry, the frog sartorius muscle was chosen for initial determinations of velocity.
