Abstract
A system and method are provided for creating an image including quantified flow within vessels of a subject. The method includes providing a single-sweep, three-dimensional (3D) image volume acquired from a subject during a single pass of a computed tomography (CT) imaging system as the subject receives a dose of a contrast agent and determining a phase shift corresponding to pulsatile contrast in vessels within the single-sweep, 3D image volume. The method further includes quantifying a flow through the vessels within the single-sweep, 3D image volume using the phase shift and generating a report including indicating flow through the vessels within the 3D image volume.
Claims30
A system for acquiring images of three-dimensional flow within an interior volume of a subject, the system comprising:
- an x-ray imaging system configured to acquire images from the subject;
- and
- a computer system configured to:
- control the x-ray imaging system to perform a single sweep of the subject to acquire a single-sweep, three-dimensional (3D) image dataset;
- reconstruct the single-sweep, 3D image dataset into a 3D image volume;
- determine a phase shift corresponding to pulsatile contrast in the vessels within the 3D image volume;
- quantify a flow through the vessels within the 3D image volume using the phase shift;
- and
- generate a report including quantified flow through the vessels within the 3D image volume.
