Abstract
Methods, systems, and apparatus for obtaining a sequence of x-ray images are disclosed. An object of interest in a first x-ray image is detected and an area of interest, based on a predicted motion of the object of interest, is determined. A second x-ray image of the area of interest is acquired using spatial x-ray modification to control an x-ray to pass through a portion of a patient corresponding to the area of interest.
Claims34
A method for obtaining a sequence of x-ray images, comprising:
- detecting an object of interest in a first x-ray image;
- determining an area of interest based on a predicted motion of the object of interest;
- and
- acquiring a second x-ray image of the area of interest using spatial x-ray modification to control an x-ray to pass through a portion of a patient corresponding to the area of interest.
A non-transitory computer readable medium storing computer program instructions for obtaining a sequence of x-ray images, which, when the instructions are executed on a processor, cause the processor to perform operations comprising:
- detecting an object of interest in a first x-ray image;
- determining an area of interest based on a predicted motion of the object of interest;
- and
- acquiring a second x-ray image of the area of interest using spatial x-ray modification to control an x-ray to pass through a portion of a patient corresponding to the area of interest.
A system for obtaining a sequence of x-ray images, comprising:
- means for detecting an object of interest in a first x-ray image;
- means for determining an area of interest based on a predicted motion of the object of interest;
- and
- means for acquiring a second x-ray image of the area of interest using spatial x-ray modification to control an x-ray to pass through a portion of a patient corresponding to the area of interest.
