This Standard applies to particular dose-related notification and alert messages appearing on the operating consoles of CT scanners. This Standard is not intended to define all notification, alert, or other messages resident on any CT scanner.
IEC TR 61948-2:2019 is valid for single photon scintillation cameras with parallel hole collimators used in planar scintigraphy and tomography. It is also valid for the SPECT portion of SPECT/CT systems with parallel hole collimators, including the co-registration between the SPECT...
This European Standard defines terms used in the field of tomography.This European Standard contains not only tomography-specific terms but also other more generic terms spanning imaging and radiography. The definitions for some of these terms feature a discussion point to refocus the term...
This standard identifies common computed tomography (CT) system (i.e. scanner) attributes that contribute to or help perform optimization/management of doses of ionizing radiation while still enabling the system to deliver the diagnostic image quality needed by...
5.1 Computed tomography (CT) is a radiographic reconstruction method that provides a sensitive technique whenever the primary goal is to locate and size planar and volumetric detail in three dimensions. 5.2 CT provides quantitative volume images as a function of density and element number...
This document specifies the general principles of X-ray computed tomography (CT), the equipment used and basic considerations of sample, materials and geometry. It is applicable to industrial imaging (i.e. non-medical applications) and gives a consistent set of CT performance parameter...
Spectral, Photon Counting Computed Tomography is a comprehensive cover of the latest developments in the most prevalent imaging modality (x-ray computed tomography (CT)) in its latest incarnation: Spectral, Dual-Energy, and Photon Counting CT. Disadvantages of the conventional...
