Ultrasound-guided prediction of local bolus velocities

A system for medical imaging, comprising:

• a computer tomography device comprising a table;
• a processor;
• a memory that stores instructions, which when executed by the processor, cause the processor to:
• compile ground truth data from measured blood flow speed at a plurality of locations of an examined portion of a body, including each of a plurality of specific locations;
• infer blood flow speeds throughout the examined portion of the body based on a computational model;
• determine a contrast medium injection duration, or a speed of a table, or both, prior to a CT scan based on the inferred blood flow speeds;
• and
• provide the determined contrast medium injection duration, or the speed of the table, or both.

A tangible, non-transitory computer readable medium that stores instructions, which when executed by a processor, cause the processor to:

• compile ground truth data from measured blood flow speed at a plurality of locations of an examined portion of a body, including each of a plurality of specific locations;
• predict with a computational model a predicted blood flow speed using the ground truth data;
• infer blood flow speeds throughout the portion of the body based on the computational model;
• determine a contrast medium injection duration, or a speed of a table, or both, prior to a CT scan based on the inferred blood flow speeds;
• and
• provide the determined contrast medium injection duration, or the speed of the table, or both.
