In addition to this simultaneous technique, helical CT [computed tomography] imaging allows for the continuous movement of the CT table during imaging. If multi-slice imaging is done in conjunction with helical scanning, reductions in scan time are possible.  1, record 1, English, - multi%2Dslice%20imaging

Helical scan uses two video heads mounted on opposite sides of a revolving drum. The video head drum spins at one frame per revolution so that each head scans one field per revolution. As the tape winds around the drum of the video head, it assumes a helical shape, thus giving the process its name.  2, record 3, English, - helical%20scan

The helical aperture facsimile transmitter is fairly common on low-to mid-volume fax units. The original is roller fed over a flatbed copy platen and illuminated by an area lamp. Lens and mirror optics reflect and focus one scan line of the moving document at a time, first through a fixed horizontal slit aperture, and then through a rotating helical aperture. The rotating of the helical aperture produces one lateral scan of the original per revolution, with the passing light being focused a final time onto a photocell for conversion to an electrical signal.  1, record 6, English, - rotating%20helical%20aperture%20scanner
