Optimizing Kilovoltage Cone-Beam Computed Tomography for Image-Guided Radiation Therapy
… (kV CBCT) has important applications in image guided radiation therapy (IGRT). In its current state, CBCT is suboptimal for these applications due to its considerable radiation dose, poor soft-tissue contrast and inaccurate Hounsfield Units as a result of in-patient scatter. The specific …

Improving Cone-Beam Computed Tomography Based Adaptive Radiation Therapy with Deep Learning
… challenge involves generating synthetic CT (sCT) images that retain CBCT anatomy while maintaining CT image quality. Clinically used sCT is typically obtained through deformable image registration (DIR) between pre-planning CT (pCT) and CBCT; however, this method often inadequately preserves CBCT …

Modelling geometric uncertainties in prostate radiotherapy
Image guided radiotherapy (IGRT) presents a range of techniques to enhance thegeometric accuracy of radiotherapy treatment. A full evaluation of such techniques,against increased cost, workload, or unnecessary radiation dose, would require theincorporation of geometric errors into existing methods …
