Abstract
A system and method are provided for medical imaging that includes acquiring, during a common imaging acquisition process, rotational, x-ray volume image data and x-ray tomosynthesis image data from a subject. The method includes reconstructing a time-resolved three-dimensional (3D) image volume from the rotational, x-ray volume image data and producing a four-dimensional (4D) image series of the subject with resolved overlapping features by selectively combining the time-resolved 3D image volume and the x-ray tomosynthesis imaging data.

A method for medical imaging comprising:
- acquiring, during a common imaging acquisition process, rotational, x-ray volume image data and x-ray tomosynthesis image data from a subject;
- reconstructing a time-resolved three-dimensional (3D) image volume from the rotational, x-ray volume image data;
- producing a four-dimensional (4D) image series of the subject with resolved overlapping features by selectively combining the time-resolved 3D image volume and the x-ray tomosynthesis imaging data.
A system for generating time resolved series of volume images including resolved overlapping features, the system comprising:
- an image processing system configured to:
- receive image data acquired from a subject having received a dose of a contrast agent using an imaging system;
- determine tomographic volume data and tomosynthesis data from the image data acquired from the subject;
- process the tomographic volume data to generate three-dimensional (3D) volume images;
- for a selected time frame in the 3D volume images, forward project through the 3D volume images using views from the tomosynthesis data corresponding to the selected time frame in the 3D volume images to create forward projected data;
- using the tomosynthesis data, reconstruct the forward projected data for the selected time frame to generate four-dimensional (4D) volume images using the 3D volume images and the;
- and
- a display configured to display the 4D volume images with the resolved overlapping features.
A system comprising:
- an x-ray imaging system configured to rotate an x-ray source and x-ray detector through a range of view angles about a subject having received a dose of a contrast agent to acquire imaging data from the subject along at least a plurality of the range of view angles;
- an image processing system configured to:
- receive the image data to determine time-resolved, tomographic volume data and tomosynthesis imaging data;
- process the time-resolved, tomographic volume data to generate three-dimensional (3D) volume images;
- for a selected time frame in the 3D volume images, forward project through the 3D volume images using views from the tomosynthesis data corresponding to the selected time frame in the 3D volume images to create forward projected data;
- using the tomosynthesis data, reconstruct the forward projected data for the selected time frame to generate four-dimensional (4D) volume images using the 3D volume images;
- and
- a display configured to display the 4D volume images with the resolved overlapping features.
A method for generating time-resolved series of volume data including resolved overlapping features, the method comprising:
- controlling a rotational x-ray imaging system to acquire time-resolved three-dimensional (3D) image volumes from a subject having received a dose of a contrast agent;
- controlling a scanning-beam digital x-ray (SBDX) imaging system to acquire tomosynthesis imaging data from the subject along a plurality of view angles included in the 3D image volumes;
- and
- producing a four-dimensional (4D) image series of the subject with resolved overlapping features by selectively combining the 3D image volumes and the tomosynthesis imaging data.
