Designing and Fabrication of a New Radiofrequency Planar microcoil for mini-Nuclear Magnetic Resonance
Introduction Radiofrequency planar microcoils are used to increase the resolution of magnetic resonance images of small samples. In this study, we aimed to design and fabricate a spiral planar microcoil constructed on a double-sided printed circuit board (PCB). It has four rings with an internal diameter of 241 microns tuned and matched at 63.8 MHz. Materials and Methods To achieve the maximum ...
متن کاملA new multi-switch circuit with adaptive capacitance for semi-active piezoelectric shunt damping
Piezoelectric-based shunt dampers are developed in recent years because of simplicity in comparison with other methods. In these methods, a part of converted mechanical energy is stored in the internal el...
متن کاملTwo-Dimensional Current Density Imaging
Imaging of electrical current by measuring the magnetic field which it produces requires the solution of the magnetic inverse problem. For a current restricted to a plane, the inverse problem can theoretically be solved by a linear spatial filtering method. We have demonstrated experimentally that currents restricted to the surface of a printed circuit board can be imaged using this method. To ...
متن کاملCT scout z-resolution improvement with image restoration methods
Currently, new applications demand utilizing CT scout images for diagnostic purposes. However, many CT scout images cannot be used diagnostically due to their poor resolution, particularly in the direction of table movement. Spatial resolution generally can be improved with image restoration techniques. Based on the principles of Wiener filtering and inverse filtering, this paper presents a mod...
متن کاملInverse modeling of HEM data using a new inversion algorithm
Helicopter-borne frequency-domain electromagnetic (HEM) surveys are used extensively for mineral and groundwater exploration and a number of environmental investigations. To have a meaningful interpretation of the measured multi- frequency HEM data, in addition to the resistivity maps which are provided in each frequency or for some particular depth levels, it is a necessity ...
