Optimizing Selective RF Pulses for Enhanced Signal Stability in Turbo Spin Echo Using a Differentiable Extended Phase Graph Model

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 214-226, July 2026.
ABSTRACT Purpose To improve slice profile consistency across echo trains in turbo spin echo (TSE) imaging, thereby reducing image blurring and increasing the accuracy of multi echo spin echo T2$$ {T}_2 $$ mapping. Methods Excitation and refocusing RF pulses were optimized for TSE using a differentiable extended phase graph model that incorporates the ...

Improved Myocardial Sodium Quantification at 7 T Using Interleaved 23Na/1H pTx MRI With Motion and Anatomy‐Based B1 Correction

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 173-190, July 2026.
ABSTRACT Purpose To improve accuracy and repeatability of myocardial 23Na quantification in cardiac MRI at 7 T by combining retrospective respiratory and cardiac motion correction with a novel anatomy‐based B1 bias field correction. Methods In this study, a dual‐nuclear interleaved 23Na/1H MRI sequence at 7 T was applied.

The Human Visual Claustrum Responses to Physical Stimulus Properties and Subjective Content During Movie Viewing

Human Brain Mapping, Volume 47, Issue 9, June 15, 2026.
To determine what drives the responses of the visual claustrum zone, we extracted physical features and collected participants' subjective ratings of naturalistic videos. Claustrum activity was associated with motion, but also with subjective ratings of arousal, valence, and interest, implying the human claustrum's role beyond sensory processing ...

A novel technique for the evaluation of the transfer function of parallel concatenated convolutional codes [PDF]

, 2006
Turbo codes, in the form of parallel concatenated convolutional codes, consist of two recursive systematic convolutional encoders separated by an interleaver. Due to the presence of the interleaver, each constituent convolutional encoder accepts as input
