Background:

Functional magnetic resonance imaging (fMRI) generates complex datasets vital for neuroscience research.
Incomplete or compressed fMRI data poses challenges for accurate blood oxygenation level dependent (BOLD) signal detection and analysis.
Existing reconstruction techniques may not optimally address simultaneous BOLD detection and data recovery.

Purpose of the Study:

To develop a novel method for simultaneous BOLD detection and data completion in fMRI.
To address the challenge of reconstructing missing samples in fMRI data with minimal quality degradation.
To evaluate the effectiveness of the proposed method against state-of-the-art techniques.

Main Methods:

A new cost function integrating BOLD detection and data reconstruction terms was formulated.
A solution employing singular value thresholding and sparsity-inducing approaches was developed.
The low-rank properties inherent in fMRI data were leveraged for reconstruction.

Main Results:

The proposed method demonstrated promising results in recovering compressed/incomplete fMRI data.
Experiments in noisy conditions showed significant improvements in data quality and analysis accuracy.
The method outperformed several state-of-the-art image reconstruction techniques.

Conclusions:

The developed technique is effective for the recovery of incomplete fMRI data.
Simultaneous BOLD detection and data completion can be achieved with high fidelity.
The approach offers a valuable tool for neuroimaging data analysis, particularly with corrupted or compressed datasets.
