Abstract
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.
Claims18
An apparatus for generating an image of an object of interest, the apparatus comprising:
- a processor;
- and
- a computer-readable storage medium storing instructions that, when executed, cause the processor to perform operations comprising:
- accessing a volumetric image of a space, the space including an object of interest and another object, the volumetric image comprising multiple regions with at least one region representing the object of interest and at least one region representing the other object;
- accessing a two-dimensional radiograph comprising data representing the object of interest and data representing the other object;
- identifying, in the volumetric image, a region representing the object of interest;
- generating a de-objectified volumetric image by disregarding the identified region;
- and
- removing from the two-dimensional radiograph a two-dimensional representation of the other object that is derived from the de-objectified volumetric image to generate a two-dimensional image of the object of interest.
A non-transitory computer-readable medium storing software comprising instructions executable by one or more processors which, upon such execution, cause the one or more processors to perform operations comprising:
- accessing a volumetric image of a space, the space including an object of interest and another object, the volumetric image comprising multiple regions with at least one region representing the object of interest and at least one region representing the other object;
- accessing a two-dimensional radiograph comprising data representing the object of interest and data representing the other object;
- identifying, in the volumetric image, a region representing the object of interest;
- generating a de-objectified volumetric image by disregarding the identified region;
- and
- removing from the two-dimensional radiograph a two-dimensional representation of the other object that is derived from the de-objectified volumetric image to generate a two-dimensional image of the object of interest.
A computer-implemented method of generating an image of an object of interest comprising:
- accessing, by one or more processors, a volumetric image of a space, the space including an object of interest and another object, the volumetric image comprising multiple regions with at least one region representing the object of interest and at least one region representing the other object;
- accessing, by the one or more processors, a two-dimensional radiograph comprising data representing the object of interest and data representing the other object;
- identifying, by the one or more processors, in the volumetric image, a region representing the object of interest;
- generating, by the one or more processors, a de-objectified volumetric image by disregarding the identified region;
- and
- removing, by the one or more processors, from the two-dimensional radiograph a two-dimensional representation of the other object that is derived from the de-objectified volumetric image to generate a two-dimensional image of the object of interest.
