Abstract

Mechanical properties of lung are closely related to lung diseases.However, currently there are no noninvasive methods that can measure the locallung tissue mechanical properties. In this paper, a technique that involvestracking the surface wave propagation and using ultrasound images to guide themeasurements is introduced. The proposed method is tested on a human subject atboth functional residual capacity (FRC) and total lung volume (TLV) conditions.The results show that the surface wave speed at 200 Hz is 4.31 m/s and 7.43 m/sat FRC and TLV, respectively. The proposed method has a clinical potential forquantifying the lung regional stiffness noninvasively.
