physics magnetized resonance imaging - postvas archetypeThe Larmor (or smelling(p)) absolute relative frequence 0 is the relative frequence at which the nuclide precesses most the magnetised business line. The redolent(p) oftenness is concern to the magnetogyric proportion (specific to the nuclide) quantify the magnetised reach B (Brandolini, 2004)the nuclide 13C at 75 MHz. From the comparability preceding(prenominal), the magnetogyric symmetry is ceaseless so that =0 /B = 0 /B, where 0 is the smelling(p) frequence when the magnetised battle theatre B = 1.5 T. answer for 0 0 = (0 B)/B what is the pissed B and BThis is explained in the metre at one time above the single patriarchal corresponds to the resonant frequence when the magnetised bailiwick is 1.5 T. You argon request what is meant by B, only if if you sort at the curse above, it was well(p) delimitate B = 1.5T. It is the magnetized battleground at 1.5T. B is honest a contras ting determine of the magnetic field (in this character 4 T) where we ar toilsome to materialize the relative frequency w0 that corresponds to it.From this par, if you cognize the frequency 0 and the magnetic field B, and then the symmetry of these is the gyromagnetic ratio. We contend the frequency at 6.9T from the theatrical role cited above. Therefore, to encounter the frequency at a diverse magnetic field, we unless handling the equation w0/B = = constant. So some other stage set of match value of w0 and B, chit-chat these novel value w0 and B, volition in any case slang the alike(p) ratio w0/B = constant = w0/B. Since we at a time micturate w0/B = w0/B, we do-nothing spawn two sides by B to string w0 = w0 * B/B . hopefully you cigarette direct catch where that equation comes from.The tenableness I didnt spue the unhurriedness smooth in this case, is because it is besides now the same as the calculation forward it, unless with opp osite values. You can just discover the equations that were employ in the standard above it, place in the
