摘要： Detection and recognition of taggant substances having predefined zero external field magnetic resonance signatures. An object comprising taggant substance(s) is irradiated with a sequence of specific excitation pulses of electromagnetic radiation within a predetermined time and frequency scanning pattern, responsive nuclear spin echo signals are received from the object with a predetermined time and frequency acquisition pattern and data indicative thereof is generated. The scanning and acquisition patterns used permit successive transmission of pulses of multiple frequencies using a two-pulse spin-echo excitation technique, or a steady state-spin echo excitation technique, and successive acquisition of multiple nuclear spin echo response signals, within a time slot between two successive excitation pulses of a specific excitation frequency. The generated data is correlated with reference data corresponding to predetermined taggant substance(s) and one or more taggant substances are identified based on the determined correlation.

摘要： A method is proposed for the simultaneous optimization of an arbitrary number of electromagnetic pulses, which act in a cooperative way, or mutually compensate each other's errors. The method generally relates to pulses which can have improved properties when cooperating with each other compared to single pulses. In experiments with several scans, undesired signal contributions can be suppressed by COOP pulses, which complements and generalizes the concept of phase cycling. COOP pulses can also be used in individual scans. COOP pulses can be optimized efficiently with the aid of an extended version of the optimal-control-theory-based gradient ascent pulse engineering (GRAPE) algorithm. The advantage of the COOP pulse method is demonstrated theoretically and experimentally for broadband and band-selective excitation and saturation pulses.

摘要： Examples of the present invention include metamaterial lenses that allow enhanced resolution imaging, for example in MRI apparatus. An example metamaterial may be configured to have μ=−1 along three orthogonal axes. Superior performance was demonstrated using such improved designs, and in some examples, imaging resolution better than λ/500 was obtained. The use of one or more lumped reactive elements in a unit cell, such as one or more lumped capacitors and/or one or more lumped inductors, allowed unit cell dimensions and hence resolution to be dramatically enhanced. In some examples, a cubic unit cell was used with an essentially isotropic magnetic permeability of μ=−1 obtained at an operating electromagnetic frequency and wavelength (λ).

摘要： Disclosed is a non-lineal statistical independent component (ICA) analysis methodology for calculating T2 or T1 distributions of nuclear magnetic resonance logs. In one aspect, the invention employs a classical blind source separation (BSS) approach with the input data (T2 or T1 distributions) being considered not only horizontally (in relaxation time units), but also vertically (in depth). The statistical variations are used for separating the principal independent components and their corresponding weighting matrix. The result of such ICA based BSS is an efficient separation of T2 components correlative to the presence of particular conditions (e.g., clay bound water, heavy oil, capillary bound water, free water, mud filtrate (water and oil), and noise). Individual saturation of estimated fluids can be calculated from the weighting matrix generated in accordance with the invention. In accordance with a further feature of the invention, it is contemplated that independent component analysis techniques may be applied to the underlying time domain data prior to its transformation to a T2 distribution. This advantageously results in “de-noising” of the signal, leading to more precise and accurate results following analysis of the T2 distribution.
摘要翻译：公开了用于计算核磁共振测井的T2或T1分布的非线性统计独立分量（ICA）分析方法。在一个方面，本发明采用经典的盲源分离（BSS）方法，其输入数据（T2或T1分布）不仅被水平地（以弛豫时间单位），而且被认为是垂直（深度）。统计变化用于分离主要独立分量及其对应的加权矩阵。这种基于ICA的BSS的结果是与特定条件（例如粘土结合水，重油，毛细管结合水，游离水，泥浆滤液（水和油）和噪声）的存在相关的T2成分的有效分离。估计流体的个体饱和度可以从根据本发明产生的加权矩阵计算。根据本发明的另一特征，可以设想，独立分量分析技术可以在其转换为T2分布之前被应用于潜在的时域数据。这有利地导致信号的“去噪”，导致在T2分布分析之后更精确和准确的结果。
