| сканирование всего исследуемого объёма за один оборот трубки томографа | single-volume acquisition (при этом не происходит "перехлеста" областей, подвергаемых действию радиации, как при сканировании по спирали: In single volume acquisition, one gantry rotation acquires up to 16 cm of coverage. This means an entire organ can be imaged as fast as 0.35 seconds. There are many advantages to fast whole-organ imaging times, including decreased radiation and contrast dose. Additionally there is no helical overscan, and no helical overlapping, which can reduce radiation by as much as 80%. CopperKettle) |
