Non-invasive measurement of absolute temperature is important for proper characterization of various pathologies and for evaluation of thermal dose during interventional procedures. The proton (hydrogen nucleus) magnetic resonance (MR) frequency shift me
For example, partial k-space acquisitions in the frequency-encoding directions, termed partial Fourier or fractional echo acquisition, reduce TE and intravoxel dephasing that can occur in complex and turbulent flows. Non-Cartesian sampling patterns have some compelling properties, particularly for ...
With this configuration, a difference between the wavelength of the first light and the wavelength of the second light is increased, and the frequency of the beat signal can be raised. Consequently, short-term stability can be enhanced.
