Maximum volume coverage in spiral computed tomography scanning

Academic Radiology, 1996
Given a slice thickness and an image noise level, volume coverage in spiral computed tomography (CT) scanning was maximized with respect to detector collimation and table increment.The maximization was analytically performed on the basis of the following relationships: (1) With the half-scan interpolation method, the slice sensitivity profile (SSP) in ...

[Spiral (helical) computer tomography].

Casopis lekaru ceskych, 1998
The introduction of spiral (helical) computed tomography (CT) has revolutionized the way established body CT examination are performed and has created new examinations as CT angiography. The production of overlapping images from single short X-ray exposure, the minimization of motion artefact and the suppression of respiratory misregistration have all ...

Technical Foundations of Spiral Computed Tomography

1996
The Introduction of continuously rotating computed tomography (CT) measurements systems provided the technological basis for spiral CT. Slip rings are used to transfer the necessary electrical energy to the rotating gantry and to transmit the measured data from the rotating part to the computer system; the cables that were used traditionally in CT ...
