Journal ArticleDOI
Temperature and SAR calculations for a human head within volume and surface coils at 64 and 300 MHz
Christopher M. Collins,Wanzhan Liu,Jinghua Wang,Rolf Gruetter,J. Thomas Vaughan,Kamil Ugurbil,Michael B. Smith +6 more
TL;DR: To examine relationships between specific energy absorption rate (SAR) and temperature distributions in the human head during radio frequency energy deposition in MRI, data are analyzed through simulation and physical measurements.
Journal ArticleDOI
Analysis of wave behavior in lossy dielectric samples at high field
Qing X. Yang,Jinghua Wang,Xiaoliang Zhang,Christopher M. Collins,Michael B. Smith,Haiying Liu,Xiao Hong Zhu,J. Thomas Vaughan,Kamil Ugurbil,Wei Chen +9 more
TL;DR: Temporal progression of the RF field indicates that the standing wave and associated dielectric resonance occurring in a pure water phantom near 300 MHz is greatly dampened in the human head due to the strong decay of the electromagnetic wave.
Journal ArticleDOI
Different excitation and reception distributions with a single-loop transmit-receive surface coil near a head-sized spherical phantom at 300 MHz.
Christopher M. Collins,Qing X. Yang,Jinghua Wang,Xiaoliang Zhang,Haiying Liu,Shalom Michaeli,Xiao Hong Zhu,Gregor Adriany,J. T Vaughan,Peter L. Anderson,Hellmut Merkle,Kamil Ugurbil,Michael B. Smith,Wei Chen +13 more
TL;DR: In this paper, the B(1) field behavior and signal intensity distribution in a 16 cm diameter spherical phantom excited by a 10-cm diameter surface coil at 300 MHz were examined.
Journal ArticleDOI
Manipulation of image intensity distribution at 7.0 T: passive RF shimming and focusing with dielectric materials.
Qing X. Yang,Weihua Mao,Jinghua Wang,Michael B. Smith,Hao Lei,Xiaoliang Zhang,Kamil Ugurbil,Wei Chen +7 more
TL;DR: To investigate the effects of high dielectric material padding on RF field distribution in the human head at 7.0 T, and demonstrate the feasibility and effectiveness of RF passive shimming and focusing with such an approach.
Journal ArticleDOI
Measurement and correction of transmitter and receiver induced nonuniformities in vivo.
TL;DR: A simple method is described for correcting intensity nonuniformities in high field MR imaging based on in vivo measurement of the transmission field B1+ and reception sensitivity maps and can be extended to the case of separate transmission and reception coils, including surface and phase array coils.
