Hardware for Enhanced MRI Contrast

Ref-Nr: TA-ZEE20160805


Kurzfassung

Simultaneous Excitation and Acquisition in MRI with an Automatic Active Cancellation System to Image Tissues with Short T2


Hintergrund

Magnetic Resonance Imaging (MRI) provides excellent cross-sectional images of the soft tissues in the human
body. In conventional MRI, the magnetization in tissue is first excited with a radio-frequency (RF) pulse, and the resultant echo signal is later acquired with an RF coil. MRI signal that decays between excitation and acquisition (T2 < 100 μs) cannot be measured, which is the case for tissues such as cortical bone or myelin.

A new RF hardware system was designed for truly simultaneous excitation and acquisition to overcome the signal loss. As the RF power levels during excitation and acquisition differ by several orders of magnitude, cancellation of unwanted excitation signal in the acquired MRI data is very important – here, a novel automatic cancellation system is realized to enable new imaging contrasts of tissues with ultra-short T2.
