| 内容記述 | In radiofrequency(RF)coil design for ultra-high field magnetic resonance(MR)imaging, short RF wavelengths present various challenges to creating a big volume coil. When imaging a human body using an ultra-high magnetic field MR imaging system(magnetic flux density of 7 Tesla or more), short wavelength may induce artifacts from dielectric effect and other factors. To overcome these problems, we developed a patch antenna array coil(PAAC), which is a coil configured as a combination of patch antennas. We prototyped this type of coil for 7T proton MR imaging, imaged a monkey brain, and confirmaed the coil's utility as an RF coil for ultra-high-field MR imaging. | |||||
