Patent ID: 8755865

Claim:
A non-transitory computer-readable storage medium having a set of instructions stored thereon which, when executed by the computer, causes the computer to: prompt a user to enter patient-specific information for a given scan patient; prompt a user to select a scan type; receive bolus tracking data for the given patient from a timing bolus scan; identify an expected post-delivery peak contrast enhancement period based on the patient-specific information, the scan type, and the bolus tracking data; provide an individualized scan protocol defining a contrast agent delivery, an x-ray dosage, and scan sequence timing, based upon the patient-specific information, the scan type, and the bolus tracking data; perform a single dynamic scan session comprising a first scan sequence to acquire image data and a second scan sequence to acquire image data; wherein, in performing the single dynamic scan session, the instructions further cause the computer to: trigger commencement of the first scan sequence to acquire image data from a region-of-interest (ROI), the first scan sequence based on the individualized scan protocol; reconstruct an image from the acquired image data; update the x-ray dosage to an updated x-ray dosage based on the reconstructed image, the updated x-ray dosage comprising a maximum x-ray dosage to be applied during the single dynamic scan session and coincides with a post-delivery peak contrast enhancement period; and trigger commencement of the second scan sequence to acquire image data from the ROI, the second scan sequence based on the updated x-ray dosage; wherein, in updating the x-ray dosage to an updated x-ray dosage, the instructions further cause the computer to: determine a present enhancement value of a contrast agent based on the reconstructed image; determine if the present enhancement value of the contrast agent has reached or will reach the expected post-delivery peak contrast enhancement period sooner or later than expected; if the present enhancement value of the contrast agent has reached or will reach the expected post-delivery peak contrast enhancement period sooner or later than expected, then adjust the x-ray dosage to the updated x-ray dosage; and if the present enhancement value of the contrast agent has reached the expected post-delivery peak contrast enhancement period at an expected time, then the updated x-ray dosage is the same as the x-ray dosage.
