    Abstract: Some embodiments of the present invention are directed towards techniques for building and using machine learning enhanced trees for automated solution determination in a technical support context. Historical technical support records with associated problems, actions and results are received and clustered. A solution determination tree is constructed from the clustered actions, and a machine learning model is trained to predict which action will lead to a solution based on an accumulated data set including a problem and subsequent results from previous actions. Using the solution determination tree and the machine learning model, classes of actions are recommended based on accumulated data for an incoming support request/problem or a result resulting from a executing a previously recommended action.

The techniques include determining a readout gradient of climbing period, platform period, and descent period, and performing a balanced steady state free precession sequence in which the readout gradient is applied in the readout direction, the analog-to-digital conversion module for collecting k-space data is activated during the climbing period maintained in the on state during the platform period, and deactivated during the descent period. The technique includes converting the k-space data collected by the analog-to-digital conversion module into uniform k-space data and generating a magnetic resonance image based on the uniform k-space data. The techniques yield more running time of the readout gradient for data acquisition, reduce the data reading time, and shorten the scanning time. The techniques also reduce the accumulated phase of the field non-uniformity in the echo interval to reduce black band artifacts.
