An evaluation of systematic errors on marker-based registration of computed tomography and magnetic resonance images of the liver

Physics and Imaging in Radiation Oncology, 2018
We demonstrated a general method to evaluate systematic errors related to Magnetic Resonance (MR) imaging sequences in marker-based co-registration of MR and Computed Tomography (CT) images, and investigated the effect of MR image quality in the co ...

Radiotherapy and Immunotherapy In Hepatocellular Carcinoma: Priming the Tumor Immune Microenvironment From Bench To Bedside

Precision Radiation Oncology, EarlyView.
The dual immunomodulatory network of radiotherapy in hepatocellular carcinoma. Radiotherapy initiates its effects by inducing immunogenic cell death and DNA double‐strand breaks. Immune Activation: Cytosolic DNA from damaged cells activates the cGAS‐STING pathway, triggering IRF3/NF‐κB‐mediated type I interferon production. This enhances dendritic cell

Salvage Androgen Deprivation Therapy Use After Definitive Radiotherapy With vs Without Androgen Deprivation Therapy in Prostate Cancer

The Prostate, EarlyView.
ABSTRACT Background For patients with unfavorable intermediate or high risk localized prostate cancer receiving definitive radiotherapy, androgen deprivation therapy reduces recurrence and improves survival but is underutilized due to toxicity concerns. Patients who forgo initial ADT may later require salvage ADT.

A Review of the Australian MRI Linac Program: From Pie in the Sky to Research Milestone

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT The Australian Magnetic Resonance Imaging (MRI) Linear Accelerator program (MRI linac) was a major research project that aimed to build and test a unique MRI linac prototype for cancer treatment. It aimed to improve radiotherapy anatomical targeting and explore physiological targeting. The purpose of this report is to summarise the development
