=== Electron beam tomography ===
{{Main|Electron beam computed tomography}}
[[Electron beam tomography]] (EBT) is a specific form of CT in which a large enough X-ray tube is constructed so that only the path of the [[electron]]s, travelling between the [[cathode]] and [[anode]] of the X-ray tube, are spun using [[Deflection yoke|deflection coils]].<ref>{{Cite book |last=Stirrup |first=James |url=https://books.google.com/books?id=SarDDwAAQBAJ&q=ebct&pg=PA6 |title=Cardiovascular Computed Tomography |date=2020-01-02 |publisher=Oxford University Press |isbn=978-0-19-880927-2}}</ref> This type had a major advantage since sweep speeds can be much faster, allowing for less blurry imaging of moving structures, such as the heart and arteries.<ref>{{Cite journal |last1=Talisetti |first1=Anita |last2=Jelnin |first2=Vladimir |last3=Ruiz |first3=Carlos |last4=John |first4=Eunice |last5=Benedetti |first5=Enrico |last6=Testa |first6=Giuliano |last7=Holterman |first7=Ai-Xuan L. |last8=Holterman |first8=Mark J. |date=December 2004 |title=Electron beam CT scan is a valuable and safe imaging tool for the pediatric surgical patient |journal=Journal of Pediatric Surgery |volume=39 |issue=12 |pages=1859–1862 |doi=10.1016/j.jpedsurg.2004.08.024 |issn=1531-5037 |pmid=15616951}}</ref> Fewer scanners of this design have been produced when compared with spinning tube types, mainly due to the higher cost associated with building a much larger X-ray tube and detector array and limited anatomical coverage.<ref>{{Cite journal |last=Retsky |first=Michael |date=31 July 2008 |title=Electron beam computed tomography: Challenges and opportunities |journal=Physics Procedia |volume=1 |issue=1 |pages=149–154 |bibcode=2008PhPro...1..149R |doi=10.1016/j.phpro.2008.07.090 |doi-access=free}}</ref>
