[edit] Usefulness

Usefullness of EBT/EBCT in assessment of coronary artery disease was discussed in JAMA this week[1]. JFW | T@lk 22:29, 17 December 2005 (UTC)


I've removed "Another technology application for EBT technology has been in rapid object/package/mail screening and sterilization of objects. Commercial demand for this application of EBT greatly increased in the US after the 11 September 2001 destruction of the NY Twin Towers and the series of anthrax contaminated letters. However, lack of acceptance of food sterilization by X-Ray has limited mass demand and development for sterilization uses." This seems to be based on a confusion between high-dose "electron-beam technology" radiation systems for killing bacteria and low-dose x-ray systems for tomography. It is a pity that an x-ray tomography technique has gotten the name "electron beam tomography". The e-beams are inside the x-ray system, and never touch the patient.

[edit] Radiation dosage

What is the difference in patients' typical radiation exposure for EBT vs convential scans? David.Throop (talk) 21:44, 9 January 2008 (UTC)

A variety of variables including patient size, study type, slice thickness, slice overlap, and other scan settings and patient varibles made accurate comparisons difficult. For example a CT heart on an EBT will consist of 40 slices, while a multichannel will typically require 200 or more, most of which are discared as "redundant radiation." Other non cardiac studies do not have this issue. EBT also is programmed to always start the beam from the posterior, this is to limit entrance dose radiation to x-ray sensitive tissue (such as breast and thyroid). For a comparison of exposure look in the physicians portal at Newportbodyscan.com. —Preceding unsigned comment added by GREGAROBERTSON (talk • contribs) 17:01, 27 April 2008 (UTC)
