From Wikipedia, the free encyclopedia. Schematic of an electron capture detector for a gas chromatograph with a 63 Ni source. An electron capture detector (ECD) is a device for detecting atoms and molecules in a gas through the attachment of electrons via electron capture ionization. The device was invented in 1957 by James Lovelock and is used in gas chromatography to detect trace amounts of chemical compounds in a sample.
Electron beam tomography Intervention Patent illustration showing a cutaway view of an electron beam computerized tomography system. Components are 22. electron gun, 23. electron beam, 24. focus coil, 27. beam bending coil, 28-31. target rings, 14. detector array, 11. scan tube. The electron beam creates x-rays at the target rings, which radiates through the patient to the detector on the opposite end of the scan tube. MeSH D014057 OPS-301 code: 3-26 (http://ops.icd-code.de/ops/code/3-26.html) Electron beam tomography From Wikipedia, the free encyclopedia Electron beam tomography (EBT), now owned by the General Electric company [1] (http://www.gehealthcare.com/usen/ct/products/ebt.html) , is a specific form of computed tomography (CAT or CT) in which the X-ray tube is not mechanically spun in order to rotate the source of X-ray photons.
