TimTX TrueForm
• Innovative techniques in the RF excitation hardware
• Uniform RF distribution in all body regions
TrueForm excitation uses amplitude and phase transmission settings optimized for
dedicated body regions. Feeding the 2 ports of the integrated body coil with an opti-
mized weighting yields a homogeneous B1 distribution
a-SPACE A version of the SPACE sequence. a-SPACE uses composite
adiabatic excitation pulses, which are insensitive to B1
spatial variations
B1 Filter An adaptive inline image filter that reduces any remnant
B1 effects without affecting image contrast
