A scatter correction device for radiative tomographic scanners is disclosed.
The
device comprises at least one steady support component and multiple beam stoppers
made of high Z materials such as lead and wolfram. Each beam stopper has two ends
fixed on the steady support component respectively. Theses beam stoppers can thus
be sustained at fixed locations by the steady support component. During scanning
an object, the device is placed between the object and detectors. But when the
scatter correction device is applied to a CT scanner, the device is placed between
object and radiation source. It attenuates part of the primary radiation with very
small affects on the scattered radiation.
