While these logs are rare and unpredictable, they’re proof that FM signals can travel far beyond their expected range under ...

An RF-penetrable PET ring that can be inserted into any existing MR system has been developed to address this issue. Employing optical signal transmission along with battery power enables the PET ring ...

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

Abstract: RF surface coils are commonly used as receivers in Magnetic Resonance Imaging (MRI) systems to acquire sensitive signals from the human body. These coils rely on cables for power and ...

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

This study aimed to evaluate cochlear signal intensity in VS patients using balanced fast field-echo (bFFE) magnetic resonance imaging (MRI) and to explore its relationship with tumor size, hearing ...

The crest factor, or peak-to-RMS ratio, is a signal metric to quantify the dynamic range of a signal. It provides a link between its RMS value and its peak value. Because the RMS value is often known ...

The MRI scanner measures the sum total of the emitted radio-frequency energy. The measured radio-frequency signal decays over time, owing to various factors, including the presence of ...

Optical beams can also be focused far more tightly than RF signals, making them more energy efficient. Mitry added that successfully achieving space-to-ground optical communications paves the way ...
