Abstract
Effective atomic numbers associated with pixels in a region are received. An effective atomic number is associated with each pixel in the region. X-ray data for the region is received, and an item within the region is identified from the x-ray data. Some of the pixels in the region are correlated with the item such that the item is associated with an effective atomic number. An image of the region is rendered. The pixels of the item have a display style based on the effective atomic number of the item.
Claims20
A method comprising:
- measuring a first effective atomic number associated with a first object;
- measuring a second effective atomic number associated with a second object, the first object overlapping at least a portion of the second object;
- and
- presenting an image, wherein a pixel associated with the overlapping of at least the portion of the second object by the first object has a display style that is based on the measured first effective atomic number.
A non-transitory computer-readable medium encoded with a computer program comprising instructions that, when executed, operate to cause a computer to perform operations comprising:
- measuring a first effective atomic number associated with a first object;
- measuring a second effective atomic number associated with a second object, the first object overlapping at least a portion of the second object;
- and
- presenting an image, wherein a pixel associated with the overlapping of at least the portion of the second object by the first object has a display style that is based on the measured first effective atomic number.
A system comprising:
- one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
- receive effective atomic numbers associated with pixels in a region;
- identify a first item within the region and a second item within the region;
- correlate at least one of the pixels in the region with the first item such that the first item is associated with a first effective atomic number;
- correlate at least one of the pixels in the region with the second item such that the second item is associated with a second effective atomic number;
- and
- a display configured to render an image of the region, the at least one pixel of the first item being associated with an overlap of at least a portion of the first item by at least a portion of the second item and having a first display style associated with the first effective atomic number, and the at least one pixel of the second item having a second display style associated with the second effective atomic number.
