Interventional magneticresonanceimaging , also Interventional MRI or IMRI , is the use of magneticresonanceimaging MRI to do interventional radiology procedures. Because of the lack of harmful effects on the patient and the operator, MR is well suited for interventional radiology , where the images produced by an MRI scanner are used to guide a minimally invasive procedure intraoperatively and or interactively. However, the non magnetic environment required by the scanner and the strong magnetic radiofrequency and quasi static fields generated by the scanner hardware require the use of specialized instruments. For example, use of non magnetic e.g. Titanium surgical instruments and MR compatible patient surveillance accessories in addition to the costly MRI scanner increase the cost of IMRI. Often required is the use of an open bore magnet, which permits the operating staff better access to patients during the operation. Such open bore magnets are often lower field magnets, typically in the 0.2 tesla range, which decreases their sensitivity tests sensitivity and Time temporal efficiency but also decreases the Radio Frequency Effective radiated power power potentially absorbed by the patient during a protracted operation. Higher field magnet systems are beginning to be deployed in intraoperative imaging suites, which can combine high field MRI with a surgical suite and even computed tomography CT in a series of interconnected rooms. Specialty high field interventional MR devices, such as the IMRIS system, can actually bring a high field magnet to the patient within the operating theatre, permitting the use of standard surgical tools while the magnet is in an adjoining space.

MagneticResonance Microscopy MRM, MRI is MagneticResonanceImaging MRI at a microscopic level. A strict definition is MRI having voxel resolutions of better than 100 m ref P. Glover and P. Mansfield, Limits to magneticresonance microscopy, Rep. Prog. Phys. 65 1489 1511, 2002 ref . Nomenclature Magneticresonance Microscopy is a term to refer to very high resolution MRI images 10 micrometres in some cases . The term is most widely used by the High Resolution MagneticResonanceImaging group from Duke University, headed by Dr. G. Allan Johnson. Differences between MRI and MRM Angular resolution Resolution Typical medical MRI resolution is about 1 mm the desired resolution of MRM is 100 m or smaller. Specimen size Medical MRI machines are designed so that a patient may fit inside. MRM chambers are usually small, typically less than 1 cm . Current status of MRM Although MRI is very common for medical applications, MRM is still developed in laboratories. The major barriers for practical MRM include Magnetic field gradient High gradient focus the magneticresonance in a smaller volume smaller point spread function , results in a better spatial resolution. The gradients for MRM are typically 50 to 100 times those of clinical systems. However, the construction of radio frequency RF coil used in MRM does not allow ultrahigh gradient. Sensitivity electronics Sensitivity Because the voxels for MRM can be 1 100,000 of those in MRI, the signal will be proportionately weaker ref R.

NMR coupling refers to the effect of nuclei on each other in atoms within a couple of bonds distance of each other in molecules. This effect causes NMR signals in a spectrum to be split into multiple peaks which are up to several hertz frequency from each other. Decoupling fully or partially eliminates splitting of the signal between the nuclei irradiated and other nuclei such as the nuclei being analyzed in a certain spectrum. NMR spectroscopy and sometimes decoupling can help determine Chemical structure structures of chemical compound s. Explanation NMR spectroscopy of a sample produces an NMR spectrum, which is essentially a graphics graph of signal intensity on the vertical axis vs. chemical shift for a certain isotope on the horizontal axis. The signal intensity is dependent on the number of exactly equivalent nuclei in the sample at that chemical shift.

Orphan date April 2010 Electrically Detected MagneticResonance EDMR is a Characterization materials science materials characterisation technique that improves upon electron spin resonance . It involves measuring the change in electrical resistance of a sample when exposed to certain microwave frequencies. It can be used to identify very small numbers down to a few hundred atoms of impurities in semiconductors . Outline of technique Image Electrically detected magnetic resonance.svg frame right A band structure energy level outline of the EDMR mechanism. A donor impurity D sits just below the conduction band C . An acceptor A sits between the donor and the valence band and provides a recombination pathway for the donor electron small blue circle to recombine with a Electron hole hole in the valence band V . A photon of a specific frequency can flip spins against the magnetic field B . To perform a pulsed EDMR experiment ref cite doi 10.1103 PhysRevB.68.245105 ref , the system is first initialised by placing it in a magnetic field. This orients the Spin physics spin s of the electron s occupying the donor and acceptor in the direction of the magnetic field . To study the donor, we apply a microwave pulse in the diagram at a resonant frequency of the donor. This flips the spin of the electron on the donor. The donor electron can then decay to the acceptor energy state it was forbidden from doing that before it was flipped due to the Pauli exclusion principle and from there to the valence band, where it Carrier generation and recombination recombines with a hole. With more recombination, there will be fewer conduction electrons in the conduction band and a corresponding increase in the resistance, which can be directly measured. Above bandgap light is used throughout the experiment ... defect to act as the acceptor.
