A Synthetic-Geometry, Mlc-Aware Machine Learning Framework for Collimator Angle Selection In Single-Isocenter Multi-Target VMAT SRS
Collimator orientation in single-isocenter multi-target (SIMT) SRS significantly impacts multileaf collimator (MLC) modulation and overall plan quality. We developed a machine learning (ML) framework to identify optimal collimator angles prior to Treatment Pl...

Log File Based Patient-Specific Quality Assurance Supplement for SRS Mapcheck on Single Isocenter Multiple Target SRS/Fsrs Treatments
SRS MapCheck has been widely used for SRS pretreatment patient-specific quality assurance (PSQA); however, it requires multiple machine deliveries due to limited array size. To improve the pretreatment PSQA efficiency for Single Isocenter Multiple Target (SIM...

Neural Event Time Series Based Functional Connectivity Analysis for Functional MRI
Functional connectivity (FC) derived from functional magnetic resonance imaging (fMRI) is a key marker of brain health and cognitive function. Most analyses rely on the blood-oxygen-level-dependent (BOLD) signal; however, BOLD reflects both neural activity an...

Robust Single-Isocenter Selection for Multi-Target SRS Using Weighted Expected Dice Similarity Coefficient
This work demonstrates the use of a weighted expected Dice similarity coefficient (wDSC) for optimizing isocenter placement in single-isocenter multi-target (SIMT) LINAC-based stereotactic radiosurgery (SRS).
