Compressed sensing MRI: a review.
- S. Geethanath, Rashmi Reddy, R. Venkatesan
- Environmental Science, Computer ScienceCritical reviews in biomedical engineering
The important requirements to qualify MRI to become an optimal application of CS, namely, sparsity, pseudo-random undersampling, and nonlinear reconstruction, are discussed.
Accessible magnetic resonance imaging: A review
This article collates recent global MR scanner density data and group them into six geographical regions based on the WHO classification, and describes demonstrated examples for each category, ranging from ultralow‐field to ultrahigh‐field MRI.
Compressive sensing could accelerate 1H MR metabolic imaging in the clinic.
A reduction of acquisition time by up to 80%, with negligible loss of information as evaluated with clinically relevant metrics, has been successfully demonstrated for hydrogen 1 MR spectroscopic imaging.
Magnetic Resonance Fingerprinting Reconstruction via Spatiotemporal Convolutional Neural Networks
This work proposes to perform MRF map reconstruction using a spatiotemporal convolutional neural network, which exploits the relationship between neighboring MRF signal evolutions to replace the dictionary matching.
PyPulseq: A Python Package for MRI Pulse Sequence Design
Pulseq is introduced, which enables pulse sequence programming in Python with zero licensing fees and easy integration with deep learning methods developed in Python, aimed at MRI researchers, faculty, students, and other allied field researchers such as those in neuroscience.
