Backscatter detector and backscatter detection apparatus including backscatter detector

Abstract

The present disclosure provides a backscatter detector, including: a plurality of detector modules arranged at different positions, where ray signal channels are independent of each other, where detection region areas of at least two first detection modules among the plurality of detector modules are different from each other, and the detection region area of each of the at least two first detection modules is adapted to a respective target first count rate. The present disclosure further provides a backscatter detection apparatus.

Dependencies are inferred from the claim text.
