我的诸位朋友们，我现在有点明白当年的校内网有多么可贵了。在2014年微信普及的年代，我的很多初中和高中同学的通讯录没能保留下来，曾经拥有的东西总不被珍惜是人性中一个严重的不足。不知道会有多少朋友可能在领英上搜到我？我的微信，手机号码是15216663550，邮箱是fineconcerto@aliyun.com。

Deep understanding in MRI including the imaging sequence, receive and transmit chain. Deep knowledge in system noise floor, receive chain architecture, field homogeneity and eddy current’s effect image quality. Deep knowledge in MR safety control, especially SAR. My routine work includes collaboration with RF engineers, software engineer and FPGA engineers, offering them system requirements knowledge. In some cases, I dig into the detailed designs (RF/DC circuitry, software code revision) to make sure the sub-system requirements met.Receive chain optimization:(mainly in Neusoft MRI)Coil driver cost down version: How to design 9.6 Ampere QBC and 9.6 Ampere surface coil (96 elements) tune/detune driver, how to dissipate the heat of the current source, how to drive coil diodes switching within 10us.

Flow down Design specifications from top level SRS to subsystem level, especially on receive coil requirements and coil configuration file explanation. I set the clinical modes for Philips value system, re-align and explain over 99% of the Philips coil resource fileSystem safety control: SAR control with B1rms: determine the B1rms value based on volunteer experimentsSubsystem phase in test method and test procedures, including the below device: QBC, Hybrid, Pre-amplifier, RF amplifier, Surface coilPhilips value platform surface coil malfunction strategy investigation and re-definefor Philips value system head coil and an old Multiva head coil- (from Invivo)Small animal coil design (for 3T Philips Ingenia system as a small research project)How to control the element decoupling, pre-amplifier stable circle, RF choke for common mode signal, how to aim at three goals together (1. Noise figure optimum match 2. Coil element tune, 3. Pre-amplifier decoupling)

MRI system trouble shooting, eddy current compensation tools and theory, system requirements and verification, system level requirements flow down to subsystem(receive chain and gradient chain)system calibration tools (eddy current measurement, super con shimming, SNR calculations, RFA calibrations)Familiar with GE value platform, installation, maintenance, cabling, surface coil, RF switch matrix, Body coil driver, system calibration process, firmware and hardware in the GE driver module
