摘要： In certain embodiments, a fence system includes a rail having a first surface having one or more apertures. The rail also includes second and third surfaces opposing one another, the first, second, and third surfaces of the rail forming a channel. The second surface and the third surface of the rail have first and second lips, respectively, the first and second lips extending into the channel. The fence system section also includes one or more pickets inserted through corresponding apertures of the first surface of the rail. Each picket has a first connection region located substantially in the channel formed by the first, second, and third surfaces of the rail such that the first connection region is substantially prevented from passing through the corresponding aperture in the first surface of the rail or between the opening defined by the first and second lips of the rail.

摘要： Three-dimensional NMR phantom includes in the preferred embodiment a set of three mutually orthogonal test plates each configured to enable testing NMR scanner performance in each of the planes containing the plates. The plates are further arranged so as to be simultaneously positionable, in use, at the isocenter of the NMR scanner to permit testing NMR scanner performance in each plane without repositioning the phantom.

摘要： There is provided a phantom for measuring a performance parameter of a nuclear magnetic resonance scanner capable of acquiring NMR data from a study object. The phantom is made up of a housing composed of a substantially non-NMR-active material, and positionable in use within a radio-frequency coil forming part of an NMR scanner. The phantom further includes a first medium disposed within the housing to load the radio frequency coil in a manner similar to that of a patient. The NMR properties of the medium are further selected such that an NMR signal, if any, produced by the medium occurs at a time other than when a performance parameter of said NMR scanner is measured. In the preferred embodiment, the phantom comprises two concentrically disposed cylinders of different diameters and a pair of end plates fastened to opposite ends of the cylinders. The first medium is disposed within the volume defined between the side walls of the cylinders and the end plates. A second medium is disposed within the volume defined within the innermost cylinder and generates the NMR test signals.
