摘要
En 中文
A radial BURST approach combining BURST excitations with projection reconstruction (PR) gradients for excitation and acquisition is introduced. With the application of PR gradients during excitation, the applied RF energy is distributed more homogeneously across the sample than in the initial BURST approach, Computer simulations of the radial BURST excitation scheme are presented and experimentally verified, Actual radial BURST implementation acquiring a 64 x 64 radial BURST image in 45 ms is reported, Extensions of the radial BURST imaging technique placing a magnetization preparation experiment in front of the whole imaging sequence are also described. Furthermore, the feasibility of combining radial BURST with a multishot approach is demonstrated.
