We have developed a noninvasive lung ultrasound surface wave elastography (LUSWE) technique for measuring superficial lung tissue stiffness. The purpose of this paper was to demonstrate the clinical use of LUSWE for assessing patients with interstitial lung disease (ILD). In LUSWE, a local 0.1s harmonic vibration is generated on the chest wall of a subject using a handheld vibrator. An ultrasound...
Ultrasonography is not widely used in clinic for lung assessment because ultrasound cannot image deep lung tissue. We have developed a noninvasive technique termed lung ultrasound surface wave elastography (LUSWE) for measuring superficial lung tissue elastic properties. The purpose of this abstract is to demonstrate the clinical use of LUSWE for assessing patients with interstitial lung disease (ILD)...
A lung ultrasound surface wave elastography (LUSWE) technique is developed to measure superficial lung tissue elastic properties. The purpose of this paper was to translate LUSWE into clinical studies for assessing patients with interstitial lung disease (ILD) and present the pilot data from lung measurements on 10 healthy subjects and 10 patients with ILD. ILD includes multiple lung disorders in...
A lung ultrasound surface wave elastography (LUSWE) technique is developed to measure superficial lung tissue elastic properties. A small, local, and short 0.1 second harmonic vibration is generated by the indenter of a handheld shaker on the skin of a subject. The ultrasound probe is positioned about 5 mm away from the indenter in the same intercostal space to measure the generated surface wave propagation...
Mechanical properties of lung are closely related to lung diseases. However, currently there are no noninvasive methods that can measure the local lung tissue mechanical properties. In this paper, a technique that involves tracking the surface wave propagation and using ultrasound images to guide the measurements is introduced. The proposed method is tested on a human subject at both functional residual...
