Arberet S, Ghesu F, Gao R, Kraus M, Sackett J, Kuusela E, et al.
Med Phys . 2025 Feb; PMID: 39935217
Background: Volumetric modulated arc therapy (VMAT) revolutionizes cancer treatment by precisely delivering radiation while sparing healthy tissues. Fluence maps generation, crucial in VMAT planning, traditionally involves complex and iterative, and...

Li T, Still J, Xu K, Lee H, Cai L, Krishnan A, et al.
Med Image Comput Comput Assist Interv . 2024 May; 14221:649-659. PMID: 38779102
The accuracy of predictive models for solitary pulmonary nodule (SPN) diagnosis can be greatly increased by incorporating repeat imaging and medical context, such as electronic health records (EHRs). However, clinically...

Yu X, Yang Q, Tang Y, Gao R, Bao S, Cai L, et al.
J Med Imaging (Bellingham) . 2024 Apr; 11(2):024008. PMID: 38571764
Purpose: Two-dimensional single-slice abdominal computed tomography (CT) provides a detailed tissue map with high resolution allowing quantitative characterization of relationships between health conditions and aging. However, longitudinal analysis of body...

Liu H, Xu Z, Gao R, Li H, Wang J, Chabin G, et al.
IEEE Trans Med Imaging . 2024 Jan; 43(5):1995-2009. PMID: 38224508
Deep learning models have demonstrated remarkable success in multi-organ segmentation but typically require large-scale datasets with all organs of interest annotated. However, medical image datasets are often low in sample...

Yu X, Yang Q, Zhou Y, Cai L, Gao R, Lee H, et al.
Med Image Anal . 2023 Sep; 90:102939. PMID: 37725868
Transformer-based models, capable of learning better global dependencies, have recently demonstrated exceptional representation learning capabilities in computer vision and medical image analysis. Transformer reformats the image into separate patches and...

Li T, Lee H, Xu K, Gao R, Dawant B, Maldonado F, et al.
J Med Imaging (Bellingham) . 2023 Jul; 10(4):044002. PMID: 37469854
Purpose: Anatomy-based quantification of emphysema in a lung screening cohort has the potential to improve lung cancer risk stratification and risk communication. Segmenting lung lobes is an essential step in...

Xu K, Khan M, Li T, Gao R, Antic S, Huo Y, et al.
Proc SPIE Int Soc Opt Eng . 2023 Jul; 12464. PMID: 37465098
In lung cancer screening, estimation of future lung cancer risk is usually guided by demographics and smoking status. The role of constitutional profiles of human body, a.k.a. body habitus, is...
