Magnetic resonance apparatus with excitation antennae system |
摘要 |
A magnetic resonance imaging system comprises an excitation antennae system (13,16) including several antennae for emitting an RF-excitation field [B1(t)]. An activation control unit (ACU) is coupled to the excitation antennae system to activate the excitation antennae system. Individual antennae are activated to simultaneously emit separate RF-excitation constituents [Bn(t)]. The RF-excitation constituents have different activation distributions over k-space. and the time required for the RF-excitation is short even for complex spatial excitation patterns.
