Toshiba majors on triple-play CT

The latest advances in CT technology are as much about minimizing X-ray dose and speeding up exam times as they are about improvements to image quality. That "triple-play" mantra appears central to the thinking behind the 320-slice AquilionONE CT scanner debuted by Toshiba America Medical Systems (Tustin, CA) at the Radiological Society of North America (RSNA) annual meeting in Chicago, IL, this week.
The works-in-progress CT machine can scan an entire organ – the heart or the brain, for example - in one rotation because it covers up to 16 cm of anatomy using 320 ultra-high-resolution 0.5 mm detector elements.
This capability (dubbed dynamic volume CT) is advantageous on two levels. First, it reduces motion artefacts significantly, eliminating the need to reconstruct slices from multiple points in time. What's more, Toshiba says AquilionONE technology involves considerably less radiation exposure - when compared against conventional CT coronary angiography, for example - owing to the elimination of overlapping CT slices.
