Special Issue Information
Dear Colleagues,
Deep learning has had a profound impact on computational imaging, offering powerful new methodologies for solving inverse problems in image reconstruction. Modern approaches leverage data-driven representations to address long-standing challenges such as sparse sampling, limited-angle acquisition, low-dose imaging, and the mitigation of complex artifacts. Yet, despite their impressive empirical success, many of these methods still lack a rigorous theoretical foundation. Questions of stability, reliability, interpretability, and the integration of learned components with classical reconstruction and regularization techniques are becoming increasingly central—both for scientific understanding and for trustworthy deployment in real-world imaging systems.
This Special Issue aims to highlight advances at the intersection of deep learning, inverse problems, and mathematical imaging. We invite contributions that develop and deepen the mathematical theory underpinning modern learning-based imaging methods. Submissions addressing the following topics are particularly welcome:
- Inverse problems and regularization theory for learned reconstruction methods;
- Representation and approximation theory relevant to neural networks and data-driven priors;
- Hybrid reconstruction algorithms that combine physical forward models with learnable components;
- Stability, robustness, and error analysis of deep learning–based reconstruction schemes;
- Optimization and training methodologies, including fine-tuning strategies and architecture design informed by mathematical principles;
- Reliability and trustworthiness of AI methods, including frameworks to mitigate hallucinations and ensure predictable behavior;
- Applications demonstrating mathematically grounded approaches to CT, MRI, PET, ultrasound, and related imaging modalities.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Mathematics is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
