Introduction: Inversion recovery (IR) TrueFISP imaging sequences have recently been used to acquire dynamic contrast enhanced (DCE) MRI data due to their short acquisition time, sensitivity to changes in tissue longitudinal relaxation times and superior signal-to-noise characteristics [1]. Use of an inversion recovery preparation offers the ability to quantify relaxation time changes at each dy...
Seismic inversion is a method that extracts acoustic impedance data from the seismic traces. Source wavelets are band-limited, and thus seismic traces do not contain low and high frequency information. Therefore, there is a serious problem when the deterministic seismic inversion is applied to real data and the result of deterministic inversion is smooth. Low frequency component is obtained fro...
