Recent physics studies have found that light can sometimes flow in unexpected ways, behaving like a so-called "superfluid." ...

Propagation-based phase-contrast X-ray computed tomography is a valuable tool for high-resolution visualization of biological samples, giving distinct improvements in terms of contrast and dose ...

NIST, Sandia National Laboratories, and International SEMATECH are developing a new type of linewidth standard for calibrating Critical Dimension (CD) metrology instruments for lithographic process ...

All three contrast-enhanced (CE) phases (e.g., Arterial, Portal Venous, and Delay) are crucial for diagnosing liver tumors. However, acquiring all three phases is constrained due to contrast agents ...

The source medical images are first transformed by NSCT followed by combining low- and high-frequency components. Two different fusion rules based on phase congruency and directive contrast are ...

Ionospheric dispersion will introduce quadratic and cubic phase error into spaceborne P-band ultrawideband synthetic aperture radar (SAR) signals, causing range ...

We introduce a strategy for learning image registration without acquired imaging data, producing powerful networks agnostic to contrast introduced by magnetic resonance imaging (MRI). While classical ...

We describe the rational design of a novel class of magnetic resonance imaging (MRI) contrast agents with engineered proteins (CAi.CD2, i = 1, 2,..., 9) chelated with gadolinium. The design of protein ...

We present a variational reconstruction algorithm for the phase-retrieval problem by using the differential interference contrast microscopy. Principally, we rely on the transport-of-intensity ...

In patients with small intestinal Crohn’s disease (CD), there is a need for a simple, non-invasive test to reduce dependence on invasive procedures (eg, enteroscopy) and costly imaging (eg, MRI or CT ...

Contrast therapy uses alternating hot and cold temperatures to reduce soreness and speed up recovery. Experts share how to do it at home safely.
