Scalable Large Field‐of‐view 3D Photoacoustic Ultrasound Imaging With Digital Multiplexing for Human Extremities

Laser &Photonics Reviews, EarlyView.
A digitally multiplexed, large‐aperture photoacoustic and ultrasound imaging architecture is presented to overcome the fundamental limited‐view artifact inherent in conventional arrays. By significantly broadening the structural detection coverage, this scalable platform enables high‐fidelity 3D visualization of human extremities within a single ...

Group‐Patch Joint Compression: Compressing Dynamic B0 and Static RF Spatial Modulations Across k‐Space Subregion Groups for Highly Accelerated MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To accelerate MRI further, rapid B0 field modulations can be applied during oversampled readout to capture additional physical information, as in Wave‐CAIPI/FRONSAC/local B0 coils modulation techniques. These methods, however, turn the Fourier readout into a non‐Fourier‐encoded dimension that cannot be reconstructed by FFT, posing ...

View Order With Arbitrary Center Echoes

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To provide explicit, vendor‐independent view‐order constructions that enable selection of an arbitrary center echo in multi‐shot imaging, with a focus on RARE and MPRAGE. Methods Vendor‐independent view‐order methods were developed to assign echo and shot indices to a prescribed set of phase encodes, enabling explicit selection of the ...

Cartesian MPnRAGE for Efficient Simultaneous Multi‐Contrast and Quantitative Relaxometry Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose T1‐weighted images with different weighting and T1 quantification can be useful in the differentiation of both native and pathologic tissue; however, acquiring multiple images requires substantial time. A rapid and robust brain imaging sequence was developed to simultaneously provide quantitative T1 maps and multiple T1‐weighted images.

The Potential for Absolute Temperature Imaging Based on Brain Metabolites Using an FID‐Shifting Approach in Gradient Echo Planar Spectroscopic Imaging (GREPSI)

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To implement and evaluate an efficient method for absolute temperature measurement using a gradient echo implementation of the echo planar spectroscopic imaging (EPSI) sequence. Methods The gradient echo EPSI sequence (GREPSI) utilizes an oscillating readout gradient together with continuous signal readout after slab selective ...

A Deep Nonlinear Subspace Modeling and Reconstruction for Diffusion‐Weighted Imaging Using Denoising Auto‐Encoder

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To present a novel, nonlinear subspace modeling and joint k–q‐space reconstruction technique for high‐resolution, multi‐band, multi‐shell diffusion‐weighted imaging (DWI). Methods High b‐value (> 1000 s/mm2), high resolution DWI has the drawback of generally low signal‐to‐noise ratios (SNRs).
