Abstract
Method and system for determining the angle of anteversion of for example bone fragments of a fractured bone are disclosed. Supported by artificial intelligence, a first object is classified in a first X-ray projection image. A a second object is classified in a second X-ray projection image. A spatial arrangement of the objects relative to each other can be determined based on a respective determination of a representation and a localization of both objects.
Claims14
A method for resolving objects in X-ray projection images comprising the steps of:
- receiving a first X-ray projection image, classifying a first object in the first X-ray projection image;
- receiving a first model of the first object;
- determining at least a first partial representation of the first object and a first localization of the first object relative to a coordinate system, by applying the first model to match the first object in the first X-ray image;
- receiving a second X-ray projection image;
- classifying a second object in the second X-ray projection image;
- receiving a second model of the second object;
- determining at least a second partial representation of the second object and a second localization of the second object relative to the coordinate system, by applying the second model to match the second object in the second X-ray image;
- and
- determining a spatial arrangement of the second object relative to the first object.
A system for determining a 3D representation and localization of an object in an X-ray projection image with respect to a coordinate system, the system comprising a processing unit configured to execute a computer program product including sets of instructions causing the system to perform the following method:
- receiving a first X-ray projection image,
- classifying a first object in the first X-ray projection image,
- receiving a first model of the first object,
- determining at least a first partial representation of the first object and a first localization of the first object relative to a coordinate system, by applying the first model to match the first object in the first X-ray image,
- receiving a second X-ray projection image,
- classifying a second object in the second X-ray projection image,
- receiving a second model of the second object,
- determining at least a second partial representation of the second object and a second localization of the second object relative to the coordinate system, by applying the second model to match the second object in the second X-ray image, and
- determining a spatial arrangement of the second object relative to the first object.
(canceled)
A non-transitory computer readable medium comprising processor-executable instructions for reading data from a processor in communication with an X-ray imaging device, the processor-executable instructions when executed on the processor in a device configure the device to:
- receive a first X-ray projection image,
- classify a first object in the first X-ray projection image,
- receive a first model of the first object,
- determine at least a first partial representation of the first object and a first localization of the first object relative to a coordinate system, by applying the first model to match the first object in the first X-ray image,
- receive a second X-ray projection image,
- classify a second object in the second X-ray projection image,
- receive a second model of the second object,
- determine at least a second partial representation of the second object and a second localization of the second object relative to the coordinate system, by applying the second model to match the second object in the second X-ray image, and
- determine a spatial arrangement of the second object relative to the first object.
