Utility
Computed tomography (CT) security inspection system with enhanced X-ray shielding
7 Sep 20
A method for scanning an object in an X-ray security inspection system, wherein the X-ray security inspection system comprises an ingoing tunnel equipped with radiation-shielding curtains, an X-ray section and an outgoing tunnel equipped with radiation-shielding curtains, the method comprising: passing the object through the ingoing tunnel at a first rate of speed and with a first extent of separation between successive objects; passing the object through the X-ray section at a second rate of speed and with a second extent of separation between successive objects; and passing the object through the outgoing tunnel at a third rate of speed and with a third extent of separation between successive objects; wherein the second rate of speed is less than the first rate of speed and the third rate of speed, and wherein the second extent of separation between successive objects is less than the first extent of separation between successive objects and the third extent of separation between successive objects.

Utility
Method for artifact reduction using monoenergetic data in computed tomography
24 Feb 20
A method for artifact correction in computed tomography, the method including: (1) acquiring a plurality of data sets associated with at least one low X-ray energy, and at least one high X-ray energy; (2) generating a plurality of preliminary images from the plurality of data sets; (3) identifying sources of an artifact source image; (4) forward projecting the artifact source image to produce artifact source data; (5) selecting and combining the plurality of data sets acquired in order to produce a new subset of data associated with the artifact, whereby to produce artifact reduced data; (6) generating a repaired data set to keep data sets associated with the low X-ray energy in artifact-free data and to introduce data sets associated with the high X-ray energy in regions impacted by an artifact; and (7) generating a final reduced artifact image from the repaired data set.
