Gradient pyramid coherence
WebGradient echo (GRE) sequences begin as a regularly spaced series of radiofrequency (RF)-pulses repeated at time interval TR. These RF-pulses are often chosen to have flip angles (α) less than 90°, but can have any value. A train of evenly spaced RF pulses produce "FID-like" and "Echo-like" signals. Each RF-pulse generates a free induction ... WebThe iconic coherence attribute is very useful for geologic feature imaging such as faults, deltas, submarine canyons, karst collapse, mass transport complexes, and more. Besides its preconditioning, the interpretation of discrete stratigraphic features on seismic data is also limited ... • Gradient structure tensor-based (Bakker, 2003 ...

WebMay 28, 2024 · Using conic-gradient (), we can now get the same result in a much simpler manner, with a single background layer instead of four! What I like to do when coding … In mathematics, the structure tensor, also referred to as the second-moment matrix, is a matrix derived from the gradient of a function. It describes the distribution of the gradient in a specified neighborhood around a point and makes the information invariant respect the observing coordinates. The structure tensor is often used in image processing and computer vision.

WebGradient Shimming Quantitative NMR: Optimizing SNR and Integral Accuracy Magnetization and Coherence NMR is fundamentally a quantum physical phenomenon. However, a significant portion of NMR can be described and understood qualitatively with a semi-classical physics picture.

WebBiologic Gradient Biologic gradient refers to the presence of a mono-tone (unidirectional) dose–response curve. We often expect such a monotonic relation to exist. For exam-ple, more smoking means more carcinogen exposure and more tissue damage, hence more carcinogenesis. Such an expectation is not always present, however.
