To the AN/FPS-115 long-distance phased-array radar,the author carries on the computation of effectiveness parameters using the most commonly used system effectiveness analysis model at present,gains its system effectiveness value.
Methods 50 healthy adult volunteers were studied with GE 1.5 T MR/i echo speed plus system and phase array head coil on the neuro optic plane (NOP). The sequences included T1-weighted imaging (T1WI) of spin echo and T2-weighted imaging (T2WI) of spin echo.
second,analyzed and compared the structures &working principles of phase array antenna and reflector antenna,and find a way to combining the characteristic of the two antennas to realize scanning,namely using microwave phase shifte system to change the phase of the parts of the antenna, to change the radiation characteristic;
In this paper, the near-field vector components were used to combine the FEM method and the uniform-geometrical theory of diffraction (UTD) method for analyzing phased array antenna mounted on an airborne platform.
A mathematical model was presented to simulate the characteristic of an acoustic field radiated from an ultrasonic linear phased array on the basis of Huygens' principle.
The effect of an irregularity of the element distribution in a two-dimensional phased array upon the efficiency of heating of biological tissue is studied in an ultrasonic surgery regime.
The aim of this study was to assess the capability of high-resolution images obtained with a commercially available pelvic phased-array surface coil to demonstrate normal hip anatomy.
Numerical simulation and comparative analysis of acoustic fields generated by two-dimensional phased arrays designed for ultrasonic surgery is conducted.
A numerical simulation and a comparative analysis of the acoustic fields produced by two-dimensional phased arrays intended for ultrasonic surgery are performed for the case of a multiple focus (in particular, 25 foci) generation.
A limitation to current reverse phase array methodology is the inability to multiplex proteomic-based endpoints as each array can only report one analyte endpoint.
This article will also illustrate some of the advances made in recent years in solution phase array chemistry including using supported reagents and simple extractive protocols for the effective preparation of high quality samples.
