New research from the University of Minnesota Medical School demonstrates that using cardiovascular magnetic resonance ...

The venous system maintains the health of our brains by removing deoxygenated blood and other waste products, but its ...

Most commonly, RF is used in medical imaging, particularly in MRI scanners. Here, it’s used to excite hydrogen atoms in the body, enabling the detection of RF signals emitted by these atoms to create ...

MRI (magnetic resonance imaging ... atoms in a static magnetic field and are subjected to a second oscillating electromagnetic field in the form of radio frequency radiation, which causes the nucleus ...

Many devices use pulsed RF signals. The obvious ones are echo-ranging systems like radar. Additionally, nuclear magnetic resonance (NMR) spectrometers and magnetic resonance imaging (MRI) systems use ...

Abstract: Demonstrated is a standalone RF self-interference canceller for simultaneous transmit and receive (STAR) magnetic resonance imaging (MRI) at 1.5T. Standalone STAR cancels the leakage signal ...

Of all the high-tech medical gadgets we read about often, the Magnetic Resonance Imaging (MRI ... are then perturbed with a carefully tuned radio frequency pulse delivered via a large drive ...

MRI machines rely on extensive arrays of radio frequency (RF) interconnects — coaxial cables and connectors — to send and receive the pulsed RF signals used to image patients. It is critical these ...

Moving to the ultrahigh field magnetic resonance imaging (UHF MRI) brought many benefits such as ... The shorter wavelength causes interferences of the RF signal and inhomogeneous excitation, which ...
