Imaging is based on the imaging of protons, using measurement of a radiofrequency signal emitted by protons regaining their thermodynamic equilibrium after their spins have been aligned in a large magnetic field.
Some of the challenges in sodium MR imaging may be eliminated by the use of a high-sensitivity radiofrequency (RF) coil, specifically, a dual-tuned (DT) proton/sodium RF coil which facilitates the co-registration of sodium and proton MR images and the evaluation of both physiochemical and structural properties of knee cartilage.
Compared with many previously published designs, this straightforward design simplifies the construction of the apparatus and simultaneously generates a B0 field parallel to the apparatus surface, allowing the use of a simple loop-type radiofrequency (RF) coil.
The use of noninvasive radiofrequency (RF) electric fields as an energy source for thermal activation of nanoparticles within cancer cells could be a valuable addition to the emerging field of nano-mediated cancer therapies.
The aim of this study is to evaluate the use of bipolar radiofrequency plasma ablation (Coblation) in the treatment of pediatric airway stenosis.
Preliminary data regarding the use of percutaneous radiofrequency ablation (RFA) for the treatment of renal cell carcinoma (RCC) are encouraging, and show the technique to be associated with minimal morbidity.
Although the use of the radiofrequency ramp makes the magnetization transfer more uniform along the different chemical groups, the line intensities of the CPMAS-TOSS spectra are still dependent on the presence of the local H density, so they do not reflect the real amount of a given type of carbon in the samples, in short, it is not a truly quantitative method.
The paper describes the possible use of a spintorque oscillator in the design of a radiofrequency macro-oscillator.
The use of radiofrequency identification (RFID) technology generates a high-volume, simple and unreliable data stream due to the technology's inherent unreliability.
In this paper, a ZnO thin film for the application of nanoactuator was deposited using a radiofrequency [RF] magnetron sputtering system under room temperature and was characterized by X-ray diffraction [XRD], energy-dispersive X-ray spectroscopy [EDS], field-emission scanning electron microscopy [FE-SEM], and atomic force microscopy [AFM].
