Pneumatically Controlled RF Coils for MRI & Spectroscopy

Radio Frequency (RF) coils transmit and receive RF signals in magnetic resonance imaging (MRI). Designing FR coils is a challenge because they often have to operate at multiple frequencies and it is difficult to enable them to resonate at multiple frequencies or switch their resonating frequencies. Positive-intrinsic-negative (PIN) diodes are commonly...

Novel Decoupling Technique for Multichannel RF Coil Arrays

Magnetic resonance imaging (MRI) is an important non-invasive imaging modality that produces detailed images of organs and tissues in a body. Using high fields, 1.5T, 3T, 7T, and above, provides higher signal-to-noise ratios (SNR), temporal resolutions and spatial resolution. MRI RF coils play a significant role in determining image quality. Surface...

Flexible, Stretchable, Wearable and Improved Dielectric Materials for MRI

MRI is an important non-invasive imaging modality that produces detailed images of organs and tissues in a body. Using high fields, 1.5T, 3T, 7T, and above, provides higher signal-to-noise ratios (SNR), temporal resolutions and spatial resolution. However, there is also an increased presence of abnormally bright and dark areas, referred to as...
