Deep Learning-Based Reconstruction for Low-Dose Sparse-View Digital Breast Tomosynthesis

Conference Progress in Biomedical Optics and Imaging Proceedings of SPIE · April 2, 2026 Purpose: Digital breast tomosynthesis (DBT) is an emerging breast imaging modality, which reduces tissue overlap and improves lesion visibility. Due to the nature of ionizing radiation in DBT and the risk of secondary cancer, scholars made extensive effort ... Full text Cite

ResUNet-based Deep Learning Technique for Ram-Lak Filter-Free CBCT Reconstruction

Conference Progress in Biomedical Optics and Imaging Proceedings of SPIE · April 2, 2026 Cone-beam computed tomography (CBCT) is widely used in image-guided radiotherapy, yet traditional reconstruction methods often introduce noise and streak artifacts, limiting the visibility of low-contrast soft tissue. This study presents a deep learning-ba ... Full text Cite

Constructing Long COVID Risk Communication in the US: A Topic Modeling-Based Critical Discourse Analysis of News Coverage

Conference Proceedings of the 43rd International Conference on Design of Communication SIGDOC 2025 · October 24, 2025 This study conducts a topic modeling-based critical discourse analysis of 111 articles from The New York Times and 89 articles from The Washington Post between 2020 and 2022. Incorporating a Latent Dirichlet Allocation (LDA)-based machine learning techniqu ... Full text Cite

Radiogenomic explainable AI with neural ordinary differential equation for identifying post-SRS brain metastasis radionecrosis.

Conference Med Phys · April 2025 BACKGROUND: Stereotactic radiosurgery (SRS) is widely used for managing brain metastases (BMs), but an adverse effect, radionecrosis, complicates post-SRS management. Differentiating radionecrosis from tumor recurrence non-invasively remains a major clinic ... Full text Link to item Cite
