Radiographers’ perspectives’ on visual grading analysis as a scientific method to evaluate image quality (2019)
Journal Article

Introduction

Radiographers routinely undertake many initiatives to balance image quality with radiation dose (optimisation). For optimisation studies to be successful image quality needs to be carefully evaluated. Purpose was to 1) discuss the st...

Impact of acquisition parameters on dose and image quality optimisation in paediatric pelvis radiography - a phantom study (2019)
Journal Article

Purpose: Within paediatric pelvis imaging there is a lack of systematic dose optimisation studies which consider age and size variations. This paper presents data from dose optimisation studies using digital radiography and pelvis phantoms representi...

Radiation protection value to the operator from augmented reality smart glasses in interventional fluoroscopy procedures using phantoms (2019)
Journal Article

Introduction: Smart glasses can be adapted to display radiographic images to allow clinician’s gaze not to be directionally fixed or predetermined by computer monitor location. This study presents an analysis of eye lens dose during interventional fl...

Scoliosis imaging : an analysis of radiation risk in the CT scan projection radiograph and a comparison with projection radiography and EOS (2019)
Journal Article
Alrehily, F., Hogg, P., Twiste, M., Johansen, S., & Tootell, A. (2019). Scoliosis imaging : an analysis of radiation risk in the CT scan projection radiograph and a comparison with projection radiography and EOS. Radiography, 25(3), https://doi.org/10.1016/j.radi.2019.02.005

Introduction: Scoliosis is defined as a deformity of the spine with lateral curvature in the coronal plane. It requires regular X-ray imaging to monitor the progress of the disorder, therefore scoliotic patients are frequently exposed to radiation. I...

ROI-based reversible watermarking scheme for ensuring the integrity and authenticity of DICOM MR images (2018)
Journal Article

Reversible and imperceptible watermarking is recognized as a robust approach to confirm the integrity and authenticity of medical images and to verify that alterations can be detected and tracked back. In this paper, a novel blind reversible watermar... Read More about ROI-based reversible watermarking scheme for ensuring the integrity and authenticity of DICOM MR images.
