摘要： A microstrip-based RF coil for use in an MRI apparatus constructed to perform human head imaging is provided and includes (a) a cylindrical non-magnetic core module having an outer surface and a longitudinal axis, a cylindrical bore extending through the core module along the longitudinal axis and defining an inner surface; and a plurality of conductive strip lines. The strip lines extend parallel to the longitudinal axis on the outer surface of the core module. The coil is constructed such that one or more of the conductive strips are divided into conductive microstrip segments with one or more tuning capacitors being bridged between two adjacent microstrip segmented sections of the conductive strip. The coil also include a shield support cylinder that is disposed concentrically about the core module and is spaced therefrom to receive the tuning capacitors. The shield support cylinder supports a conductive segmented shield that is operatively connected to the conductive strips through tunable capacitors at a front and rear of the shield support cylinder.

摘要： In one aspect, a restraining assembly for an awake animal within a magnetic resonance imaging (MRI) device is provided and includes a body restrainer having a first part and a second part that hold a body of the awake animal therebetween. The assembly is of a dual coil design in that it has a volume coil for generating an excitation RF signal and an RF surface coil for receiving an RF response from the animal. The assembly further includes components that serve to restrain movements of the animal, thereby eliminating motion artifacts during the MRI procedure. For example, the assembly preferably includes an adjustable hip holder that has a first section that seats against and applies a restraining force to a buttocks/hip area of the animal and a second section that is adjustably coupled to a pivoting member that is attached to the first section of the body restrainer such that the hip holder is adjustable in both a longitudinal direction along a length of the body restrainer and an up/down direction within the body restrainer between the first and second parts thereof. The pivoting member having features that permit the hip holder to be locked in a desired location so that a sufficient restraining force is applied the animal.

摘要： The present invention relates to systems of methods of detecting and measuring inclusions in liquid metals. More particularly, non-metallic inclusions having a conductivity level different from the liquid metal melt are forced to migrate and are collected on a measurement surface using electromagnetic Lorentz forces. The inclusions and their concentrations are detected at the measurement surface using either an electrostatic detection system or an optical detection system.
