Abstract
A method includes performing a contrast enhanced computed tomography (CT) scan of tissue of interest of a subject, with an imaging system having a radiation source and a detector array, in which a peak contrast enhancement of the tissue of interest, a full range of motion of the tissue of interest, and an entire volume of interest of the tissue of interest are concurrently imaged during a single rotation of the radiation source and the detector array of the imaging system over an entire or a predetermined sub-portion of a breathing cycle.
Claims10
An imaging system, comprising:
- a radiation source that rotates around an examination region about a z-axis and emits radiation that traverses the examination region;
- a detector array, located across the examination region, opposite the radiation source, that detects radiation traversing the examination region;
- wherein the detector array includes a plurality of rows of detectors along the z-axis direction providing a z-axis coverage;
- wherein the coverage is such that an entire volume of interest of moving tissue of interest is scanned during a single revolution of the source;
- wherein the scan is performed during the single revolution and covers a complete moving cycle of the tissue of interest;
- and
- wherein the scan images a peak contrast uptake of contrast material by the tissue of interest during the revolution;
- and
- a reconstructor that reconstructs a four dimensional contrast enhanced data set based on the scan.
