Christoph Dietrich, in Ultrasound in Medicine & Biology, 2021 Dynamic range The dynamic range (DR), or compression, is somewhat similar to the window/level in CT. It represents the amplitude between the maximum and minimum values of the imaged signal in the display (Lee et al. 2015). A ...
Ultrasound interferometery has been used to determine the velocity of propagation of compressional waves in two different samples of crude oil over a wide ... S Arafin,George, AK,Singh, RN - 《Journal of Geophysics & Engineering》 被引量: 8发表: 2006年 Wide-range multiphase equation of state...
Fig. 1. Schematic of ultrasound wave propagation and measurement in two broad method classes: (a) a representative long-range method, where the whole extent of the container is considered, and (b) an example of proposed short-range method, where a subsection of the container in contact with...
A fullwave model of the nonlinear wave equation with multiple relaxations and relaxing perfectly matched layers for high-order numerical finite-difference solutions ndemonstrated in 2D and 3D for ultrasound imaging applications where the long\npropagation lengths, heterogeneous media in the human body, ...
were firstly determined from a B-mode image and subsequently matched in the shear wave elastography image. The biceps femoris shear wave velocity was measured with the probe placed exactly in the same region as the sciatic nerve, by adjusting the ultrasound scan depth-wise. Legend: BF – Bicep...
The achievement of the subwavelength focusing feature, which focuses acoustic power into a very small region, is a most important task in the medical ultrasound field, from diagnostics1to therapeutics2. The achievement of subwavelength focusing makes it possible to discover and cure very tiny substanc...

These techniques include non-ionizing radiation (ultrasound, magnetic resonance), and ionizing radiation like X and γ-rays. The use of ionizing radiation represents a risk for the patient that must be less than the benefit it brings to the patient. The technology of the equipment and the ...
She received both BSc degree in Physics (in 2018) and MSc in Nuclear Physics (in 2019) from the University Complutense of Madrid. Her research focuses on photoacoustic imaging and ultrasound tomography. Joaquin L. Herraiz received the B.S. degree in Physics in 2003 and his PhD in Physics ...
During hyperthermia treatment the temperature is increased by around 4–8 °C in the tumor region by means of radio frequencies, ultrasound or microwaves, whereby it is important that the temperature does not exceed the upper limit. Microwave temperature monitoring offers a non-invasive and painless...
