Quantitative Ultrasound and Cell Deaththe detection of such changes utilizing mid- to high-frequency ultrasound. Cell death introduces structural changes in the cell’s nucleus including nuclear condensation and fragmentation. These result in differentiable echogenicities of living cells and cells dying of programmed cell death (apoptosi

Modeling of Ultrasound Backscattering by Aggregating Red Blood Cellsation (i.e., aggregate size, structure and packing organization). The paper focuses on studies aimed at explaining factors affecting the frequency dependent backscatter coefficient (BSC). The theoretical structure factor model of ultrasound backscatter by aggregated RBCs is presented. Computer simul

Backscatter Quantification for the Detection of Metastatic Regions in Human Lymph Nodeschapter describes high-frequency, three-dimensional (3D) QUS methods to characterize freshly dissected lymph nodes of cancer patients. 3D ultrasound radio-frequency data were acquired from lymph nodes using a 25.6-MHz center-frequency transducer. Each node was inked prior to tissue fixation to recov

Quantitative Ultrasound for Tissue-type Imaging of the Prostate: Implications for Planning and Guidimonitoring non-surgical therapy. Current, commonly used, conventional means of imaging the prostate do not reliably depict cancerous lesions, and as a result, biopsy needles are placed with respect to visible anatomic features of the gland, treatment tends to involve the entire gland, and post-treat

Therapy Monitoring and Assessment Using Quantitative Ultrasoundtherapy. In this chapter, QUS techniques, i.e., spectral-based analysis and envelope statistics, are examined for their ability to detect, image and quantify the therapeutic response of diseased and normal tissues ex vivo and in vivo. Specifically, high frequency QUS (>20?MHz) techniques were used t

Review of Envelope Statistics Models for Quantitative Ultrasound Imaging and Tissue Characterizationcases, are discussed in the context of quantitative ultrasound (QUS) imaging. The Nakagami distribution is presented as an approximation of the homodyned K-distribution. The main assumptions made are: (1) the absence of log-compression or application of non-linear filtering on the echo envelope of t

The Quantitative Ultrasound Diagnosis of Liver Fibrosis Using Statistical Analysis of the Echo Envelation of tissue disease using the characteristics of the ultrasound echo signal, such as power spectrum, texture parameters, local attenuation and statistical characteristics, requires an understanding of the relationship between complicated scatterer structures and the echo signal. In this chapter,

Recent Applications of Acoustic Microscopy for Quantitative Measurement of Acoustic Properties of Sorasonic frequency. Scanning acoustic microscopy (SAM) uses 100?MHz or higher frequency ultrasound. The spatial resolution achieved by a 100?MHz and 1?GHz ultrasound SAM are 15 and 1.5?μm, respectively. This level of detail enables cellular imaging. There are three unique features of SAM compared wit

Acoustic Microscopy of Cells images with a resolution that approach conventional optical microscopy, or provide quantitative data about the mechanical properties of the material being investigated. This chapter focuses on acoustic microscopy methods to investigate how single cells change during biological processes such as mit

Methods for Forward and Inverse Scattering in Ultrasound Tomographyrovide quantitative images of acoustical parameters such as speed of sound, attenuation, and density from measurements of pressure fields. Throughout the years, several algorithms that rely on different wave propagation models have been developed. In this chapter, the fundamentals of forward and inv
