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...
Skin stiffening is an early biomarker of many systemic fibrotic disorders. The Modified Rodnan Skin Score (MRSS) is considered the gold standard measurement in clinical studies of systemic sclerosis (SSc). However, the MRSS is a palpation method. We have developed a noninvasive ultrasound surface wave elastography (USWE) technique for measuring skin elastic properties. The purpose of this paper is...
The purpose of this paper was to demonstrate a noninvasive technique to measure elastic properties of human eyes using ultrasound surface wave elastography (USWE) technique. Twenty eyes of 10 healthy subjects (age 44–63; mean 51 years) were studied. A localized harmonic vibration for 0.1 second at 100 Hz was generated by using a spherically-tipped vibrator (3 mm diameter) placed on the closed eyelid...
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...
