TrueForm Retains the Spectral Integrity on the MAGNETOM Verio
نویسندگان
چکیده
It is well known that good quality spectra are dependent on the magnetic field homogeneity of the magnet. The field homogeneity, in turn, is dependant on the magnetic field strength, the bore design etc. In the case of the MAGNETOM Verio, a 3T wide and shorter bore scanner, these factors are of concern for the spectroscopy community. The Verio uses an innovative technology known as “TrueForm”. In TrueForm the two ports of the CP body coil are unequally fed with a non-orthogonal phase difference which causes an improvement in homogeneity as well as a reduction in power deposition. TrueForm design in the Verio mitigates the homogeneity effects that are normally experienced with both a wide and shorter bore at the magnetic field strength of 3T. This innovation was made possible by innovations in the magnet design, gradients, RF, acquisition and processing protocols. The TrueForm magnet design produces a cylindrically optimized homogeneous volume and a cylindrical shape for the gradient linearity volume. Here we demonstrate that the Verio, equipped with TrueForm, allows for spectroscopy to be undertaken satisfactorily for brain and breast.
