Abstract
A method and system for optimizing a magnetic resonance imaging (MRI) protocols to improve MRI value are described herein. An example method includes selecting an imaging sequence, selecting at least one objective function from a plurality of objective functions, simulating a relationship between controllable acquisition variables and the objective functions, trade-offing the influence of the controllable acquisition variables for MRI value in whole k-space acquisition to determine optimal acquisition condition, acquiring at least one MR image using the optimal acquisition condition, receiving or estimating outcomes related to the at least one MR image, and evaluating an MR image value for the MR image based on the outcomes.
