SYSTEM AND METHOD FOR TRACKING CEREBRAL BLOOD FLOOD FLOW IN FMRI |
摘要 |
A system and method for analyzing blood flow in a subject's brain is provided. In some aspects, the method includes analyzing fMRI data to identify signals related to blood flow, and selecting a zero time lag seed regressor using the identified signals. The method also includes correlating the selected seed regressor to identify a subset of the fMRI data that correlates with the seed regressor and is offset in time, combining the subset of the data to determine a time-delayed regressor, and performing repetitions to obtain a number of time-delayed regressors, where for each repetition, the seed regressor is adjusted using a previous time-delayed regressor. The method further includes analyzing the data using the time-delayed regressors to determine blood delivery from vessels across the brain, and generating a report. In some aspects, a second recursive procedure may be performed using an optimized seed regressor obtained from a first recursive procedure. |
