摘要： The invention concerns an improved magnetic resonance apparatus and method for substantially reducing the dead time of the apparatus, in order to recover as much of the submicrosecond FID signals as quickly as possible. A double-channel, out-of-phase signal combination is employed. Two RF receiving coils are arranged with identical ringing characteristics, preferably mutually perpendicular to one another. The RF signal received by one coil is phase shifted by 180 DEG , amplified, and combined with the amplified RF signal received by the other coil. The ringing components cancel, whilst the FID components in phase quadrature do not. The transmitter/receiver apparatus may be of duplex or crossed coil configuration. In the latter case, one of the receiver coils may be oriented parallel to the main field so that it receives no FID signal and operates only to reduce the dead time. The invention is particularly well suited for imagers and spectrometers using pulsed electron paramagnetic resonance (EPR), for the detection of free radicals in biological systems, or for pulsed nuclear magnetic resonance (NMR), where relaxation times are of the order of 100ns to 10 mu s.
摘要翻译：本发明涉及一种改进的磁共振装置和方法，用于大大减少装置的死区时间，以尽可能快地恢复尽可能多的亚微米FID信号。采用双通道异相信号组合。两个RF接收线圈被布置成具有相同的振铃特性，优选彼此相互垂直。由一个线圈接收的RF信号相移180°，放大，并与由另一个线圈接收的放大的RF信号组合。振铃分量取消，而相位正交的FID分量不能。发射机/接收机设备可以是双工或交叉线圈配置。在后一种情况下，接收器线圈中的一个可以平行于主场定向，使得其不接收FID信号并且仅操作以减少死区时间。本发明特别适用于使用脉冲电子顺磁共振（EPR），用于检测生物系统中的自由基或用于脉冲核磁共振（NMR）的成像器和光谱仪，其中弛豫时间为100ns至10 亩。

摘要： The behaviour of particles is tested by placing a suspension of the particles in a chamber in which an electrode array is arranged to generate a spectrum of different frequency dielectrophoretic fields. The behaviour of the particles at the different frequencies can be studied in a convenient and rapid manner. The apparatus and method can be used for a variety of purposes, including characterising the properties of specified particle types, or analysing the particle population in a fluid. It is also possible to expose the particles to different fluid parameters to extend the test spectrum in other senses.

摘要： The invention relates to a method of obtaining phase information in magnetic resonance imaging (MRI) and employing this information to produce an enhanced image. In the past, magnetic resonance imagers have obtained data which contains phase as well as magnitude information. Often the phase information has been discarded in order to avoid image artefacts, which are usually attributable to motion. The present invention employs a technique in which this phase information is used in order to improve image quality, in an analogous method to that used in optical microscopy.
