Systems and methods for flow rate compensated acquisition parameters for medical imaging

A medical imaging system comprising:

• an acquisition unit comprising a computed tomography (CT) detector configured to collect imaging data;
• and
• a processing unit comprising one or more processors operably coupled to the acquisition unit, the processing unit configured to:
• receive image data of a first location of a region of interest (ROI) when located in a field of view of the acquisition unit as a contrast material injected into the ROI passes through the first location, wherein the contrast material successively traverses from the first location to a second location of the ROI, the second location being spaced apart from the first location;
• determine from the image data of the first location when a first contrast metric is reached;
• after determining the image data of the first location, position the second location of the ROI in the field of view of the CT detector;
• acquire image data of the second location as the contrast material passes through the second location;
• and
• determine from the image data of the second location when the contrast material reaches a second contrast metric.

A tangible and non-transitory computer readable medium comprising one or more computer software modules configured to direct one or more processors to:

• acquire image data of a first location of a region of interest (ROI) when located in a field of view of a medical imaging system as a contrast material injected into the ROI passes through the first location, wherein the contrast material successively traverses from the first location to a second location of the ROI, the second location being spaced apart from the first location;
• determine from the image data of the first location when a first contrast metric is reached;
• after determining the image data of the first location, position the second location of the ROI in the field of view of the medical imaging system;
• acquire image data of the second location as the contrast material passes through the second location;
• and
• determine from the image data of the second location when the contrast material reaches a second contrast metric.
