Histological examination remains the most direct means to assess the inflammatory tissue. It however is still with the nature of invasiveness and is time consuming for the preparation of tissue slices. The slice apparently is not applicable for a long term observation of the tissue in situ. For these reasons, this study is to explore another approach to assess the inflammatory skin using strengths...
It was shown previously that ultrasonic scattering from whole blood varies during the flow cycle under pulsatile flow both in vitro and in vivo. It has been postulated that the cyclic variations of the backscattering signal are associated with red blood cell (RBC) aggregation in flowing whole blood. To obtain a better understanding of the relationship between blood backscattering and RBC aggregation...
Recently endolaryngeal sonography at frequencies ranging from 10 to 30 MHz has been found to be useful in diagnosing diseases of the vocal folds (VF). However, image resolution can be further improved by ultrasound at higher frequencies, necessitating the measurement of high-frequency acoustic properties of VF tissue. The ultrasonic parameters of integrated backscatter, sound velocity, and frequency-dependent...
