Spectral sense inverting
WebThe SPAIR pulse sequence is identical to SPIR except it uses a 180º adiabatic fat saturating inversion pulse. SPAIR (SPectral Attenuated Inversion Recovery), like SPIR, is a hybrid … WebThe high pass generated with spectral reversal looks indeed like the mirror of the low pass, but its impulse response does not sum up to 0 but more like to a value with an magnitude of 1e-6 or 1e-7. This is basically 0 in float32 but noticable in float64. The inverted filter does sum up to basically 0 in float64: I get something like 1.5e-16.
