The Mathematics and Computer Graphics of Spirals in Plants
Leonardo, 1983This is a study of the pattern known as spiral phyllotaxis-literally, "leaf-arrangement", but applied to the arrangement of seeds, florets, petals, scales, twigs and so on-and which is very widespread in plants. A number of stages in the refinement of model-making are recorded.

[Spiral (helical) computer tomography].
Casopis lekaru ceskych, 1998The 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 ...

Spiral computed tomography — a short overview
1998During the late 1980s and at the beginning of the 90s, fast CT (computed tomography) scanners with an examination time of less than 1 second, based on the slipring technology, were introduced into clinical practice. These scanners offered the opportunity to have continuous data acquisition over a multitude of 360° scans, and it seemed feasible that ...
