RF plasma was applied for the reduction of human blood and bovine blood in which essential proteins to lives were included. Atomic oxygen and singlet molecular oxygen are significantly important for the treatment of protein by RF oxygen plasma. The reduction rate of the protein was analysed by FTIR spectra, and the light emitted from oxygen plasma was detected by spectrometer. The ratio of emis...

A 30-year-old female reported sporadic paresthesia and tremors in the left hand, hemiface, and hemibody. MRI showed a lesion in the left pontomesencephalic junction (Figure 1), with brushlike enhancement after gadolinium administration, well depicted with maximum intensity projection (MIP) technique (Figure 2). Despite its unusually large dimensions, the lesion was diagnosed as a capillary tela...

Background/introduction Anti-tumor immune response caused by High Intensity Focused Ultrasound (HIFU) therapy has been a subject of controversy. Most agree that the response is more likely to be induced by mechanical, rather than thermal effects of HIFU. The goal of the current work was to study the effect of HIFU-induced liquefaction of a tumor on tumor-specific and non-specific T-cell mediate...

Introduction Ultrasound is widely applied in the clinical field today, such as ultrasound contrast agent imaging, High Intensity Focused Ultrasound (HIFU), Extracorporeal Lithotripsy, sonodynamic therapy. Some of these have a close relation to the dynamic behavior of micro bubbles and that of a bubble cloud. In an ultrasound imaging, micro bubbles are used as contrast agents. Extracorporeal Foc...

A new approach for characterizing high intensity focused ultrasound (HIFU) transducers is presented. The technique is based upon the acoustic streaming field generated by absorption of the HIFU beam in a liquid medium. The streaming field is quantified using digital particle image velocimetry, and a numerical algorithm is employed to compute the acoustic intensity field giving rise to the obser...

Introduction. Balanced steady-state free precession (bSSFP) imaging is a fast acquisition technique giving high signal with very short repetition times. However, its steady-state is very sensitive to off-resonances (and therefore B0 inhomogeneity), leading to nonuniform intensity and signal voids across the image. Adding a linear increase in the phase to the RF pulses moves the signal voids to ...
