TransQA: deep hybrid transformer network for measurement-guided volumetric dose prediction of pre-treatment patient-specific quality assurance
Phys Med Biol. 2023 Sep 15. doi: 10.1088/1361-6560/acfa5e. Online ahead of print.ABSTRACTOBJECTIVE: Performing pre-treatment patient-specific quality assurance (prePSQA) is considered an essential, time-consuming, and resource-intensive task for volumetric modulated arc radiotherapy (VMAT) which confirms the dose accuracy and ensure patient safety. Most current machine learning and deep learning approaches stack excessive convolutional/pooling operations (CPs) to predict prePSQA with two-dimensional or one-dimensional information input. However, these models generally present limitations in explicitly modeling long-range d...

Analysis and prediction of liver volume change maps derived from computational tomography scans acquired pre- and post-radiation therapy
This study leverages the use of deep learning-based segmentation and biomechanical deformable image registration (DIR) to analyze and predict this relationship. Pre- and Post-EBRT imaging data were collected for 100 patients treated for HCC, CC or CRC with IMRT with prescription doses ranging from 50 to 100 Gy delivered in 10 to 28 fractions. For each patient, DIR between the portal and venous (PV) phase of a diagnostic CT scan acquired before RT planning, and a PV phase of a diagnostic CT scan acquired after the end of RT (on average 147±36 days) was performed to calculate Jacobian maps representing volume changes in the...

Ring artifacts correction for computed tomography image using unsupervised contrastive learning
Phys Med Biol. 2023 Sep 15. doi: 10.1088/1361-6560/acfa60. Online ahead of print.ABSTRACTComputed tomography (CT) is a widely employed imaging technology for disease detection. However, CT images often suffer from ring artifacts, which may result from hardware defects and other factors. These artifacts compromise image quality and impede diagnosis. To address this challenge, we propose a novel method based on dual contrast learning image style transformation network model (DCLGAN) that effectively eliminates ring artifacts from CT images while preserving texture details. 
Approach: Our method involves simulating ri...

Congener-specific uptake and accumulation of bisphenols in edible plants: Binding to prediction of bioaccumulation by attention mechanism multi-layer perceptron machine learning model
In this study, the uptake, translocation, and accumulation of five bisphenols (BPs) in carrot and lettuce plants were investigated through hydroponic culture (duration of 168 h) and soil culture (duration of 42 days) systems. The results suggested a higher bioconcentration factor (BCF) of bisphenol AF (BPAF) in plants than that of the other four BPs. A positive correlation was found between the log BCF and the log Kow of BPs (R2carrot = 0.991, R2lettuce = 0.784, P < 0.05), while the log (translocation factor) exhibited a negative correlation with the log Kow (R2carrot = 0.882, R2lettuce = 0.723, P < 0.05). The result...

Deep learning in MRI-guided radiation therapy: A systematic review
J Appl Clin Med Phys. 2023 Sep 15:e14155. doi: 10.1002/acm2.14155. Online ahead of print.ABSTRACTRecent advances in MRI-guided radiation therapy (MRgRT) and deep learning techniques encourage fully adaptive radiation therapy (ART), real-time MRI monitoring, and the MRI-only treatment planning workflow. Given the rapid growth and emergence of new state-of-the-art methods in these fields, we systematically review 197 studies written on or before December 31, 2022, and categorize the studies into the areas of image segmentation, image synthesis, radiomics, and real time MRI. Building from the underlying deep learning methods,...

Machine Vision and Image Analysis in Anesthesia: Narrative Review and Future Prospects
This article summarizes recently published works of interest, provides a brief overview of techniques used to create machine vision applications, explains frequently used terms, and discusses challenges the specialty will encounter as we embrace the advantages that this technology may bring to future clinical practice and patient care. As machine vision emerges onto the clinical stage, it is critically important that anesthesiologists are prepared to confidently assess which of these devices are safe, appropriate, and bring added value to patient care.PMID:37712476 | DOI:10.1213/ANE.0000000000006679

Protein classification by autofluorescence spectral shape analysis using machine learning
Talanta. 2023 Sep 9;267:125167. doi: 10.1016/j.talanta.2023.125167. Online ahead of print.ABSTRACTDepending on the relative numbers and spatial arrangement of Tryptophan (Trp; W) and Tyrosine (Tyr; Y) residues, different proteins produce distinct autofluorescence (AF) spectral shapes when excited at ∼280 nm. Yet, considering the vast number and heterogeneous forms in nature, visual analysis and precise identification of proteins based on their AF spectra is challenging and further compounded in cases when different proteins produce substantially similar AF spectral shapes. There is, thus, a serious need to develop a meth...

Association between co-exposure to phenols, phthalates, and polycyclic aromatic hydrocarbons with the risk of frailty
Environ Sci Pollut Res Int. 2023 Sep 15. doi: 10.1007/s11356-023-29887-7. Online ahead of print.ABSTRACTThe phenomenon of population aging has brought forth the challenge of frailty. Nevertheless, the contribution of environmental exposure to frailty remains ambiguous. Our objective was to investigate the association between phenols, phthalates (PAEs), and polycyclic aromatic hydrocarbons (PAHs) with frailty. We constructed a 48-item frailty index using data from the National Health and Nutrition Examination Survey (NHANES). The exposure levels of 20 organic contaminants were obtained from the survey circle between 2005 an...
