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.

Impact of body part thickness on AP pelvis radiographic image quality and effective dose (2018)
Journal Article

Introduction: Within medical imaging variations in patient size can generate challenges, especially when selecting appropriate acquisition parameters. This experiment sought to evaluate the impact of increasing body part thickness on image quality (...

A novel method for comparing radiation dose and image quality, between and within different X-ray units in a series of hospitals (2018)
Journal Article

Objectives: To develop a novel method for comparing radiation dose and image quality (IQ) to evaluate adult chest X-ray (CXR) imaging among several hospitals.
Methods: CDRAD 2.0 phantom was used to acquire images in eight hospitals (17 digital X-r... Read More about A novel method for comparing radiation dose and image quality, between and within different X-ray units in a series of hospitals.

Construction and validation of a low cost paediatric pelvis phantom (2018)
Journal Article
Ali, M., Hogg, P., Johansen, S., & England, A. (2018). Construction and validation of a low cost paediatric pelvis phantom. European Journal of Radiology, 108, 84-91. https://doi.org/10.1016/j.ejrad.2018.09.015

PURPOSE: Imaging phantoms can be cost prohibitive, therefore a need exists to produce low cost alternatives which are fit for purpose. This paper describes the development and validation of a low cost paediatric pelvis phantom based on the anatomy o...

An investigation of pressure ulcer risk, comfort and pain in medical imaging (2018)
Journal Article

In this study, we investigated the interface pressure of healthy volunteers on medical imaging (MI) table surfaces to determine the risks of developing pressure ulcers (PU). We also investigated volunteers’ perception of pain and comfort while lying... Read More about An investigation of pressure ulcer risk, comfort and pain in medical imaging.

Calculating individual lifetime effective risk from initial mean glandular dose arising from the first screening mammogram (2018)
Journal Article

Objectives: To use the initial mean glandular dose (MGD) arising from the first screening mammogram to estimate the individual total screening lifetime effective risk.
Methods: Organ doses from FFDM screening exposures (craniocaudal and mediolatera... Read More about Calculating individual lifetime effective risk from initial mean glandular dose arising from the first screening mammogram.

Breast compression across consecutive examinations among females participating in BreastScreen Norway (2018)
Journal Article

Objectives
Breast compression is used in mammography to improve image quality and reduce radiation dose. However, optimal values for compression force are not known, and studies has found large variation in use of compression forces between breast...

An investigation into the validity of utilising the CDRAD 2.0 phantom for optimisation studies in digital radiography (2018)
Journal Article

Objectives: To determine if a relationship exists between low contrast detail (LCD) detectability using the CDRAD 2.0 phantom, visual measures of image quality (IQ) and simulated lesion visibility (LV) when performing digital chest radiography (CXR).... Read More about An investigation into the validity of utilising the CDRAD 2.0 phantom for optimisation studies in digital radiography.

Effective lifetime radiation risk for a number of national mammography screening programmes (2018)
Journal Article

Background and purpose: The performance of mammography screening programmes is focussed mainly on breast cancer detection rates. However, when the benefits and risks of mammography are considered, the risk of radiation-induced cancer is calculated fo...
