- Abstract: A desire to achieve large medical imaging datasets keeps increasing as
machine learning algorithms, parallel computing, and hardware technology
evolve. Accordingly, there is a growing demand in pooling data from multiple
clinical and academic institutes to enable large-scale clinical or
translational research studies. Magnetic resonance imaging (MRI) is a
frequently used, non-invasive imaging modality. However, constructing a big MRI
data repository has multiple challenges related to privacy, data size, DICOM
format, logistics, and non-standardized images. Not only building the data
repository is difficult, but using data pooled from the repository is also
challenging, due to heterogeneity in image acquisition, reconstruction, and
processing pipelines across MRI vendors and imaging sites. This position paper
describes challenges in constructing a large MRI data repository and using data
downloaded from such data repositories in various aspects. To help address the
challenges, the paper proposes introducing a quality assessment pipeline, with
considerations and general design principles.

Magnetic resonance imaging (MRI) raw data, or k-Space data, is complex-valued, containing both magnitude and phase information.
We introduce $textitPhaseGen$, a novel complex-valued diffusion model for generating synthetic MRI raw data conditioned on magnitude images.

Magnetic particle imaging (MPI) is an emerging medical imaging modality which offers a unique combination of high temporal and spatial resolution, sensitivity and biocompatibility.
For system-matrix (SM) based image reconstruction in MPI, a huge amount of calibration data needs to be acquired prior to reconstruction in a time-consuming procedure.
Due to its size, handling the calibration data can be challenging.
We propose a data space aimed at improving the efficiency of SM-based image reconstruction in MPI.

Resting-state MRI functional (rs-fMRI) is increasingly employed in multi-site research to aid neurological disorder analysis.
Many methods have been proposed to reduce fMRI heterogeneity between source and target domains.
But acquiring source data is challenging due to concerns and/or data storage burdens in multi-site studies.
We design a source-free collaborative domain adaptation framework for fMRI analysis, where only a pretrained source model and unlabeled target data are accessible.

Deep Learning (DL) models have achieved state-of-the-art performance in diagnosing multiple diseases using reconstructed images as input.
DL models are sensitive to varying artifacts as it leads to changes in the input data distribution between the training and testing phases.
We propose to use other normalization techniques, such as Group Normalization and Layer Normalization, to inject robustness into model performance against varying image artifacts.

The application of compressed sensing (CS)-enabled data reconstruction for accelerating magnetic resonance imaging (MRI) remains a challenging problem.
This is due to the fact that the information lost in k-space from the acceleration mask makes it difficult to reconstruct an image similar to the quality of a fully sampled image.
We propose a deep learning-based attention hybrid variational network that performs learning in both the k-space and image domain.
