Abstract
A radiation (e.g., X-ray) source and collimator assembly with no moving parts provides a swept-line scan of radiation suitable for imaging or analyzing radiation scattered from an object. Scatter radiation is sensed by (e.g., scintillation devices) to produce a signal which is then able to be processed to produce an image, or to be analyzed.

9. A system comprising:
-
a. an electronically scanning radiation source that directs at least one pencil beam of radiation in a raster-scan across an object;
b. at least one radiation detector which detects scatter of said radiation from the object and produces a corresponding signal; and
c. an imaging system that generates an image of the object from the signal. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

18. A method for scanning an object or material to ascertain its content or composition, comprising:
-
using a scanning radiation source and beam collimation assembly having no moving parts to emit radiation in the direction of an object to be scanned;
detecting radiation scattered from the object and producing a corresponding electrical signal; and
processing the electrical signal to yield an image of the object or analyze the object. - View Dependent Claims (19, 20)
