Aquilion{sub}TM whole-body helical CT scanner

摘要

We have developed the Aquilion{sub}(TM), the top-of-the-line system in the Toshiba whole-body X-ray CT helical scanner series, which permits a fast scan of 0.5 s. In order to realize a 0.5s scan, new designs have been incorporated to suppressgantry vibration due to higher speed rotation and to withstand the centrifugal force of up to 13 G, which is at least double that in existing models. In addition, a compact, large-capacity, high-voltage generator which does not require insulation oil,and an X-ray tube with superior cooling efficiency were developed.This system makes it possible to scan a wider field in a shorter time, improving diagnostic capability and examination efficiency, as well as supporting new clinical cardiac and vascular applications that were difficult with existing models.
