| 1 | Computed tomography scans of paranasal sinuses before functional endoscopic sinus surgery显示文摘This review aims to familiarize the radiologist with the common types of sinus surgery including their indications and techniques.We also illustrate how surgeons interpret 3D sinus anatomy when evaluating computed tomography(CT)studies.Preoperative evaluation by CT is mandatory for all patients undergoing functional endoscopic sinus surgery(FESS).In the past decade in particular,CT of the paranasal sinuses has become a roadmap for FESS.The radiologist's goal is to report on five key points:the extent of sinus opacification,opacification of sinus drainage pathways,anatomical variants,critical variants,and condition of surrounding soft tissues of the neck,brain and orbits.We present a systematic approach to the use of coronal,axial,and sagittal images in CT evaluation before FESS. | Emma C Cashman Peter J MacMahon David Smyth | 2011 | World Journal of Radiology2011，3，8： | 10 |
| 2 | The design and implementation of a ROACH2+GPU based correlator on the Tianlai dish array显示文摘A digital correlator is a crucial element in a modern radio telescope.In this paper,we describe a scalable design for the correlator system of the Tianlai pathfinder array,which is an experiment dedicated to testing key technologies for conducting a 21cm intensity mapping survey.The correlator implements the FX design,which firstly performs a fast Fourier transform(FFT) including polyphase filter bank(PFB) computation using a Collaboration for Astronomy Signal Processing and Electronics Research(CASPER) Reconfigurable Open Architecture Computing Hardware-2(ROACH2) board,then computes cross-correlations by employing Graphics Processing Units(GPUs).The design has been tested both in laboratory and in actual observation. | Chen-Hui Niu Qun-Xiong Wang David MacMahon Feng-Quan Wu Xue-Lei Chen Ji-Xia Li Hai-Jun Tian Guillaume Shippee Dan Werthimer Xiao-Ping Zheng | 2019 | Research in Astronomy and Astrophysics2019，19，7： | 2 |
