Accurate multislice gradient echo T(1) measurement in the presence of non-ideal RF pulse shape and RF field nonuniformity.
A methodology is presented for estimating T(1) using a two-point technique with a standard multislice gradient echo sequence. The method explicitly corrects for the shape of the RF pulse and for spatial variations in transmitted RF field intensity. Including these factors in the calculation of T(1) gives a substantial improvement in accuracy and precision of two-point gradient echo T(1) measure...
متن کاملFocusing an arbitrary RF pulse at a distance using time-reversal techniques
In this paper, we demonstrate the use of a time reversal (TR) technique to effectively focus an arbitrary RF pulse at a remote location from a single-feed aperture for directed energy applications. The TR focusing is achieved by backing the aperture with a reverberating cavity, whose multipath environment enables the reconstruction of the aperture field distribution needed for directing the ene...
متن کاملA time - reversal method for an acoustical pulse
In the recent years a considerable amount of mathematical work have been devoted to the study of reeected signals obtained by the propagation of pulses in randomly layered media. We refer to 1] for an extensive survey and applications to inverse problems. The analysis is based on separation of scales between the correlation scale of the inhomogeneities present in the medium, the typical wavelen...
متن کاملA Simple Iterative Alignment Method Using Gradient Descending Minimum Search
Large tracking systems of present experiments in high energy physics consist of typically 10 individual detector elements. The alignment procedure has to fix up to 10 parameters. We propose a simple and robust iterative updating alignment method using reconstructed tracks. The geometrical parameters are adjusted using a gradient descending minimum search which does not require handling of large...
متن کاملRF Pulse Design Using Combinatorial ODtimization
The current RF pulse techniques do not take into account the practical implementation using finite resolution in both time sampling and amplitude discretization. Here, we formulate the problem of RF pulse design as a combinatorial optimization problem. The objective function is formulated to minimize the L1 difference between the desired profile and the computed profile using the exact solution...
