PURPOSE:To enable photography in a short time, by fixing an NMR signal emitting object to a surface coil for NMR imaging to limit the image sensing area. CONSTITUTION:A surface coil 1 is made up of a ring section 2 and a support section 3 integral therewith and a signal generation disc ...
PURPOSE:To ensure an easy mounting work for a surface coil and the prevention of the drop thereof by forming a coil holder in such a way as to have an approximately C-shaped or O-shaped section for retaining the surface coil toward the inside of a retaining part, and placing a plate sp...
To improve the application value of surface coil in MRI, the imaging effects of surface coilswith different gauge on standard model was measured, and primarily investigated the problem on how toproperly select surface coil. It is showed that, a set of value for each surface coil can be decide...
First, FastCSR may facilitate various surface-based multimodal neuroimaging analyses including data derived from MEG, EEG, anatomical and functional MRI [17,18,19, 60,61,62]. While surface-based analyses may generate more precise spatial localization than traditional volume-based analyses [9], this...
A novel mono-surface antisymmetric 16-element transmit/receive (Tx/Rx) coil array was designed, simulated, constructed, and tested for cardiac magnetic resonance imaging (cMRI) in pigs at 7 T. The cardiac array comprised of a mono-surface 16-loops wit
58). Imaging data were collected in a 3 T Siemens Prisma MRI scanner with a surface coil array (eight elements). Twenty-seven 1.5 mm coronal slices (no gap) were acquired using single-shot interleaved gradient-recalled echo planar imaging. Imaging parameters were as follows: voxel size:...
The present study describes the advantageous application of a surface coil to electron paramagnetic resonance (EPR) irradiation in Overhauser-enhanced MRI (OMRI). OMRI is a double-resonance method for imaging free radicals based on the Overhauser effect. Proton NMR images are recorded without and wit...
Phantom coils were distributed throughout the volume encompassed by the array with a variety of orientations. Each phantom coil was precisely machined and located to better than 25 μm and 10 mRad accuracy. Excellent agreement between model-calculated and measured magnetic field distributions of all...
(MPRAGE) sequences (van der Kouwe et al., 2008) with volume navigators (vNav) for motion correction (Tisdall et al., 2012) (mocoMPRAGE) were obtained in the sagittal plane, at average image resolution of 1 mm3, using a 32-channel adult head coil (see Appendix Table 3 for more ...
The forklift directly picks the coil eye into the box; 2. The forklift carries the coiled steel and rolls the coil into the container. Which packing method to choose should be determined in combination with the actual number of pieces per box and the volume of the ...
