It is produced by the stochastic motion of free electrons in the RF coil, which is a conductor, and by eddy current losses in the patient, which are inductively coupled to the RF coil. The presence of noisy patterns on the acquired MR signal is a problem that affects not only the ...
The concurrent PET-MR system for imaging the brain was brought up in the year of 2007, where the PET system with RF coil is fitted within the bore of the magnet (Schlemmer et al.2008). This module of design is adopted by Siemens brain PET insert by using the magnetic field of 3 T ...
Conclusion In this study, a new reconstruction method, termed multi-step joint-blade SENSE (MJB SENSE), is proposed for accelerated PROPELLER MRI and demonstrated in both simulation and in vivo experiments. MJB SENSE PROPELLER exploits the sharable information existing among different blades, and ...
These results are achieved without the need for additional hardware to reduce the RF field inhomogeneity, such as dielectric pads or multi-channel transmit coil. Naturally, the method can also benefit from a dielectric pad or multi-channel RtαrsFacannfsi1em, lRditFAdc,iosaitnlrsdibtoTuit...
In vivo imaging of tumor-bearing mice. All tumor-bearing mice weighing 20–25 g (tumor vol- ume: ~100 mm3) were scanned using 7 T MRI (Bruker Biospec) with a transceiver RF volume coil (diameter: 40 mm) for the mouse body, maintained under anesthesia with 1.0–1.5% ...
The Biot-Savart simulation results obtained for the opposed solenoid coil should follow closely those trends prescribed by the two equations defining the B-field of a conventional solenoid. Inside a solenoid, the equation for calculating the transverse magnetization, Bxy, is given as: ...
As used herein, a lead conductor may refer to one or more electrical conductors of lead 20 and/or lead extension 18 which electrically couple electrodes 26 to one or more components of IMD 16, such as, processing circuitry 42, sensing circuitry 46, simulation generator 44 and/or the like....
