Synopsis

Keywords: fMRI Analysis, fMRI Analysis

Motivation: Currently, Sparse and Subspace Constraints have not been used for ultra-short TR Line-scanning fMRI accelerated reconstruction.

Goal(s): Shorten Line-scanning fMRI scanning time and improve image quality.

Approach: Reconstruct simulated undersampled Line-scanning fMRI data using reconstruction algorithms and perform fMRI analysis.

Results: Accelerated reconstruction can improve the quality of ultra-short TR Line-scanning fMRI images, but there is a possibility of losing BOLD signals.

Impact: Laying the groundwork for future research on Line-scanning fMRI acceleration methods.
