Abstract
Certain embodiments of the present invention provide a method for three-dimensional cine EBA/CTA imaging. The method includes monitoring a cardiac cycle of a patient and selecting a trigger point along the cardiac cycle. When the cardiac cycle of the patient reaches the trigger point, a computed tomography (CT) scan of the patient is initiated. At least two CT scans of the patient are performed during a time period over two or more cardiac cycles. A cine angiography image is constructed from the at least two CT scans.
Claims33
A method for obtaining cine angiography images with a computed tomography (CT) scanner, comprising:
- monitoring a cardiac cycle of a patient;
- selecting at least one independently configurable trigger array, said at least one trigger array including a plurality of trigger points;
- initiating at least one CT scan of said patient based on said at least one trigger array;
- selecting at least one additional independently configurable trigger array, said at least one trigger array including an additional plurality of trigger points;
- initiating at least one additional CT scan of said patient based on said at least one additional trigger array;
- performing at least two CT scans of said patient during a time period over two or more cardiac cycles;
- and
- constructing a cine angiography loop from said at least two CT scans.
A method for obtaining cine loop images with a computed tomography (CT) scanner, comprising:
- monitoring a cardiac cycle of a patient;
- selecting at least one independently configurable trigger array, said at least one trigger array including a plurality of trigger points associated with two or more events with respect to said patient;
- initiating at least one CT scan of said patient based on said at least one trigger array;
- selecting at least one additional independently configurable trigger array, said at least one trigger array including an additional plurality of trigger points associated with two or more events with respect to said patient;
- initiating at least one additional CT scan of said patient based on said at least one additional trigger array;
- performing at least two CT scans of said patient during a time period over two or more cardiac cycles;
- sweeping an electron beam along a target to generate an x-ray fan beam to perform at least two CT scans;
- and
- constructing a cine angiography loop from said at least two CT scans.
