Future
Whether the inherent sweep-speed advantage will maintain commercial viability of the EBT design remains unclear at this time. As of 2002, one major company owns and offers models in both competing designs, with engineering cross-pollination of techniques between the product design teams. As of 2005, it increasingly appears that the spiral CT designs, especially those with (b) 64 detector rows, (b) 3×360°/sec rotation speeds and designed for cardiac imaging, are largely replacing the EBT design from a commercial and medical perspective. However, EBT still offers sweep speeds of effectively 50×360°/sec rotation speeds and lower radiation exposure. The latest version of the EBT eSpeed offers a 33 ms sweep time.
While there are very few of these scanners in use, this technology represents the fastest commercial CT temporal resolution.

Famous quotes containing the word future:
“For a parent, its hard to recognize the significance of your work when youre immersed in the mundane details. Few of us, as we run the bath water or spread the peanut butter on the bread, proclaim proudly, Im making my contribution to the future of the planet. But with the exception of global hunger, few jobs in the world of paychecks and promotions compare in significance to the job of parent.”
—Joyce Maynard (20th century)
“For me chemistry represented an indefinite cloud of future potentialities which enveloped my life to come in black volutes torn by fiery flashes, like those which had hidden Mount Sinai. Like Moses, from that cloud I expected my law, the principle of order in me, around me, and in the world.... I would watch the buds swell in spring, the mica glint in the granite, my own hands, and I would say to myself: I will understand this, too, I will understand everything.”
—Primo Levi (19191987)
“The power we exert over the future behavior of our children is enormous. Even after they have left home, even after we have left the world, there will always be part of us that will remain with them forever.”
—Neil Kurshan (20th century)
