Neonatal chest radiography : influence of standard clinical protocols and radiographic equipment on pathology visibility and radiation dose using a neonatal chest phantom (2020)
Journal Article

Introduction: Little is known about the variations in pathology visibility (PV) and their corresponding radiation dose values for neonatal chest radiography, between and within hospitals. Large variations in PV could influence the diagnostic outcome...

Introduction: Adolescent idiopathic scoliosis (AIS) is a spinal deformity that can affect young children. It requires frequent exposure to X-rays to monitor the deformity, which can lead to the development of radiation-induced cancer later in life. T...

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...
