In conventional MRI, bone and air appear as signal voids due to signal decay, making them difficult to distinguish. This remains a major limitation for synthetic CT (sCT) generation in MRI-based radiotherapy. Although AI-based approaches have shown promise, t...
Stereotactic radiosurgery (SRS) requires submillimeter geometric accuracy and commonly relies on combined computed tomography (CT) and magnetic resonance imaging (MRI). However, MRI is susceptible to geometric distortions that increase with distance from the...
In MRI-only radiotherapy treatment pathways, synthetic CT (sCT) images can be used for dose calculation, but achieving adequate bony detail in the pelvic region remains challenging. This study aimed to evaluate the performance of multiple AI-based algorithms...
Standard glioblastoma (GBM) radiotherapy planning uses uniform margins to expand the gross tumour volume (GTV) to the clinical target volume (CTV) and planning target volume (PTV). This approach does not account for patient-specific microscopic infiltration o...
