So far, to account for ultrasonic attenuation in soft tissues molecular scale relaxation theory is retained. In addition to these mechanisms, the authors have obtained experimental evidence proving the role also plaid by cellular scale resonance mechanisms. Moreover, in addition to incoherent diffusion, it has been found that some tissues exhibit some coherent diffusion. All these experimental findings allows us to establish the feasability of non invasive ultrasonic biopsies.
到目前为止，为了解释软组织中的超声衰减，分子尺度弛豫理论仍被保留。除了这些机制外，作者还获得了实验证据，证明细胞尺度共振机制也发挥了作用。此外，除了非相干扩散外，还发现一些组织表现出一些相干扩散。所有这些实验结果使我们能够确定无创超声活检的可行性。
