| 释义 | 〔iconoscope〕An early form of a television-camera tube, equipped for rapid scanning of an information-storing, photoactive mosaic.光电摄像管：电视摄像管的早期的一种形式，用于快速扫描储存信息库和光活性的画面〔strobe〕A spot of higher than normal intensity in the sweep of an indicator, as on a radar screen, used as a reference mark for determining distance.作参照的指示点：在指示器的扫描中如在雷达屏幕上强度离于一般的点，用于测定距离的参照标记〔sonogram〕An image, as of an unborn fetus or an internal body organ, produced by ultrasonography. Also called echogram ,sonograph ,ultrasonogram 超声波扫描图：由超声波扫描所产生的未出生的胎儿或某一体内器官的图像 也作 echogram,sonograph,ultrasonogram〔scan〕A picture or an image produced by this means.CAT片：用这种方法扫描出的图片〔scan〕To move a finely focused beam of light or electrons in a systematic pattern over (a surface) in order to reproduce or sense and subsequently transmit an image.扫描：以系统的方式移动高度集中的光或电子束使之掠过（一个表面），目的是再现或感知并达到传递图象〔Cormack〕South African-born American physicist. He shared a 1979 Nobel Prize for developing the CAT scan x-ray technique.柯麦科，阿伦·马克利奥德：(生于 1924) 南非裔美国物理学家，他因发明CAT扫描X-光技术而获1979年诺贝尔奖〔vidicon〕A small television camera tube that forms a charge-density image on a photoconductive surface for subsequent electron-beam scanning.光导摄像管：在光电导表面形成电荷聚集图像的一种微小的电视摄像管，用于以后的电子光束扫描〔scintigram〕A two-dimensional record of the distribution of a radioactive tracer in a tissue or organ, obtained by means of a scanning scintillation counter. Also called scintigraph ,scintiscan 闪烁图：在组织或器官内放射性追踪物分布的平面记录，由扫描交烁计数器得到 也作 scintigraph,scintiscan〔orthicon〕A television camera pickup tube, more sensitive than the iconoscope, that uses a low-velocity electron beam to scan a photoactive mosaic. Also called image orthicon 正析（摄）象管：一种运用低带电子来扫描感光栅格的电视摄象管，比光电摄象管更敏感 也作 image orthicon〔ultrasonograph〕An apparatus for producing images obtained by ultrasonography.超声图记录仪：产生用超声波扫描获得图像的仪器〔target〕A structure in a television camera tube with a storage surface that is scanned by an electron beam to generate a signal output current similar to the charge-density pattern stored on the surface.靶电极：电视摄像管中的一种结构，其记忆表面被一束电子流扫描后能产生与该表面上存储的电荷密度方式相似的一束信号并输出电流〔Hounsfield〕British engineer and inventor. He shared a 1979 Nobel Prize for developing the CAT scan x-ray technique.豪恩斯弗尔德，戈弗雷·纽博尔德：(生于 1919) 英国工程师及发明家，他因发展CAT扫描X光技术而与人分享1979年的诺贝尔奖 |
