Abstract
Systems and methods of imaging an organ of a patient include obtaining a plurality of two-dimensional (2D) tomosynthesis projection images of the organ. An x-ray image of the organ is obtained. A three-dimensional (3D) volume of the organ is reconstructed from the plurality of projection images and the x-ray image. A synthetic 2D image of the organ is generated from the plurality of projection images and the x-ray image. The x-ray image is mapped to the 3D volume. A user selection of an object of interest in the x-ray image or the synthetic 2D image is received. A plane through the 3D volume that crosses the selected object of interest is identified and displayed.

A method of imaging an organ of a patient, the method comprising:
- obtaining a plurality of two-dimensional (2D) tomosynthesis projection images of the organ by rotating an x-ray emitter to a plurality of orientations relative to the organ and emitting a first level of x-ray energization from the emitter for each projection image of the plurality of projection images;
- obtaining an x-ray image of the organ with a second level of x-ray energization
- reconstructing a three-dimensional (3D) volume of the organ from the plurality of tomosynthesis projection images and the x-ray image;
- and
- generating a synthetic 2D image of the organ from the plurality of tomosynthesis projection images and the x-ray image.
A method of imaging an organ of a patient, the method comprising:
- obtaining a plurality of two-dimensional (2D) tomosynthesis projection images of the organ by rotating an x-ray emitter to a plurality of orientations relative to the organ and emitting a first level of x-ray energization from the emitter for each projection image of the plurality of projection images;
- obtaining an x-ray image of the organ with a second level of x-ray energization;
- reconstructing a three-dimensional (3D) volume of the organ from the plurality of tomosynthesis projection images;
- mapping the x-ray image to the 3D volume;
- presenting the x-ray image in a graphical user interface (GUI) presented on a graphical display;
- receiving a user selection of an object of interest in the x-ray image;
- identifying a plane through the 3D volume;
- and
- presenting the identified plane on the graphical display.
A system of medical imaging, the system comprising:
- an x-ray emitter capable of producing x-rays at a first energization level and a second energization level, the x-ray emitter being rotatable to a plurality of orientations;
- an x-ray detector in at least partial alignment with the x-ray emitter;
- a processor operably connected to the x-ray emitter and the x-ray detector, the processor operates the x-ray emitter and detector to rotate about an organ to be imaged and obtain a plurality of two-dimensional (2D) projection images of the organ and the processor operates the x-ray emitter and detector to acquire an x-ray image of the organ at the second energization level;
- and
- a graphical display operably connected to the processor, the graphical display operated by the processor to present the x-ray image of the organ in a graphical user interface (GUI) presented on the graphical display;
- wherein the processor reconstructs a three-dimensional (3D) volume of the organ from the plurality of projection images and maps the x-ray image to the 3D volume, and upon receiving a user selection of an object of interest in the x-ray image presented in the GUI on the graphical display, the processor identifies a plane through the 3D volume based upon a map of the x-ray image to the 3D volume and operates the graphical display to presented the identified plane.
