GENERATING A REPRESENTATION OF AN OBJECT OF INTEREST
A volumetric image of a space is acquired from an imaging system. The space includes an object of interest and another object, and the volumetric image includes data representing the object of interest and the other object. A two-dimensional radiograph of the space is acquired from the imaging system. The two-dimensional radiograph of the space includes data representing the object of interest and the other object. The two-dimensional radiograph and the volumetric image are compared at the imaging system. A two-dimensional image is generated based on the comparison. The generated two-dimensional image includes the object of interest and excludes the other object.
1 . A materials screening system comprising:
a scan region configured to receive an object;
a source of radiation configured to illuminate the scan region;
a sensor configured to sense radiation from the scan region;
a processor;
a computer-readable storage medium storing instructions for generating a two-dimensional image of the object of interest, the instructions, when executed, cause the processor to perform the following:
generate a volumetric image of the scan region based on the sensed radiation, the volumetric image including a representation of an object of interest and another object,
generate a two-dimensional radiograph of the scan region based on the sensed radiation, the two-dimensional radiograph including a representation of the object of interest and the other object,
analyze the volumetric image to identify the object of interest or the other object,
based on the analyzed volumetric image, generate a second two-dimensional image that excludes the object of interest,
compare the two-dimensional radiograph and the second two-dimensional image that excludes the object of interest, and
generate a two-dimensional image based on the comparison, the two-dimensional image including the object of interest and excluding the other object.
