Conventional medical imaging technologies, including ultrasound, have continued to
improve over the years. For example, in oncology, medical imaging is characterized by high …

Ultrasound imaging is now in very widespread clinical use. The most important
underpinning technologies include transducers, beam forming, pulse compression, tissue …

After several decades of debate, it is now widely acknowledged that apoptosis, also known
as programmed cell death, is central to homoeostasis and normal development and …

Quantitative imaging methods using high-frequency ultrasound (HFU) offer a means of
characterizing biological tissue at the microscopic level. Previously, high-frequency, 3-D …

Purpose: Quantitative ultrasound techniques have been recently shown to be capable of
detecting cell death through studies conducted on in vitro and in vivo models. This study …

A two dimensional simulation study was performed to investigate the photoacoustic signal
properties of non-aggregated and aggregated erythrocytes. Spatial distributions of non …

We use picosecond ultrasonics to image animal cells in vitro—a bovine aortic endothelial
cell and a mouse adipose cell—fixed to Ti-coated sapphire. Tightly focused ultrashort laser …

High frequency ultrasound imaging (20 to 60 MHz) is increasingly being used in small
animal imaging, molecular imaging and for the detection of structural changes during cell …

We demonstrate a method for differentiating tissue disease states using the intrinsic texture
properties of speckle in optical coherence tomography (OCT) images of normal and tumor …

Two mouse models of mammary cancer (a carcinoma and sarcoma) were examined using
quantitative ultrasound (QUS). Scatterer property estimates, ie, the average scatterer …
