Accurate prediction of origin-destination (OD) demand is critical for service providers to efficiently allocate limited resources in regions with high travel demands. However, OD distributions pose significant challenges, characterized by sparsity, complex spatial correlations within or chains, and potential repetition due the recurrence similar semantic contexts. These challenges impede traditional graph-based approaches, which connect two vertices through an edge, from performing...
Purpose or ObjectiveReduced-dose protocols have been made available on Varian Edge kV cone beam CT (CBCT) and Halcyon MV CBCT.To assist clinicians in choosing optimal imaging modality for specific patient anatomy, this work compared the dose positioning accuracy of CBCT using various scanning phantoms.
