The paper describes a new magnetic resonance imaging (MRI) phased-array receive-only (Rx) coil for studying decompression sickness and disorders of hyperbaricity, including nitrogen narcosis. Functional magnetic resonance imaging (fMRI) is noninvasive, is considered safe, and may allow stud...
Receive-only head coils employing a modified solenoid design were developed for a 0.15-T imager with horizontal main static and radiofrequency transmit fie... BJD Marrocco,DJ Drost,FS Prato - 《Magnetic Resonance in Medicine》 被引量: 6发表: 1987年 ELECTRIC CONTROL MODULE SOLENOID PUMP The pre...
The widespread use of MRI has created a demand for high quality images for current and emerging applications. High quality images are currently acquired by using application specific receive coils that fit close to the patient's body to produce high signal to noise ratio. These coils are manufact...
MRI coil is shown inFig. 2a. We use octagonal coils with a diameter of 8.7 cm (ref.32), with a conductor width of 0.5 cm and four capacitors evenly spaced throughout the loop as shown inFig. 2b. To fabricate the coils, we print the coils layer by layer from solution, ...
(SNR), the surface coils are used, although the RF magnetic field (B1) in the specified imaging region of MRI produced by volume RF coils is much more homogeneous than that produced by surface coils. 要达到更好的信号噪音比 (SNR),表面卷用于,虽然RF磁场 (B1) 在MRI的指定的想象区域由volume...

Common RF coils of vertical-field MR are not adaptive to a combined system because there is no unhindered path for ultrasound beams to pass. A special three-channel receive-only RF coil with a 27 cm aperture to pass ultrasound beams was designed and reported first time. Phantom scan, body ...
