Abstract
The present disclosure provides various methods and systems for performing magnetic resonance studies. In accordance with many embodiments, image or other information of interest is derived from super radiant pulses.
Claims23
A method for performing a magnetic resonance protocol comprising:
- a) providing a magnetic resonance device including (i) a main magnet for providing a background magnetic field along a first direction, (ii) at least one radio-frequency coil, and (iii) at least one gradient coil that can be controlled to define at least one region of interest;
- b) defining a region of interest;
- c) introducing a sample to be studied into the region of interest;
- d) inducing electromagnetic feedback between the nuclear magnetization of at least one set of nuclei within the sample and at least one nearby resonant coil to cause the vector direction of the nuclear magnetization of the at least one set of nuclei to rotate to a desired angle with respect to the first direction of the background magnetic field to generate at least one electromagnetic pulse of transverse magnetization Mxy;
- and
- e) detecting the pulse of transverse magnetization with the at least one radio-frequency coil.

A method for inverting the vector direction of at least one set of nuclei contained in a sample, comprising:
- a) providing a controller;
- b) providing a power source operably coupled and controlled by the controller;
- c) providing an electromagnet in operable communication with the power source and controller;
- d) disposing a sample having nuclei to be inverted into a sample chamber in electromagnetic communication with the electromagnet;
- e) operating the controller to actuate the power source to induce an electromagnetic pulse in the electromagnet to orient the vector direction of nuclei of a sample situated in the sample chamber;
- and
- e) operating an injector assembly to direct the sample into a magnetic resonance system.
