Theory of optimising radiation protection among diagnostic radiographers depicted as a model.

Background: When radiation protection practices are suboptimal, it becomes necessary to take additional steps to optimise practices.

Aim: Therefore, this study aimed to develop a model to facilitate radiation protection among diagnostic radiographers.

Setting: The study was conducted in South Africa.

Australian graduate radiographers' perspectives and experiences of work readiness.

Introduction: Graduate radiographers entering their qualified positions need to orientate and familiarise themselves with a rapidly changing work environment to deliver a high standard of diagnostic imaging services. During this transitional phase, these newcomers also strive to meet self-expectations and workplace expectations. This study was performed to understand the work readiness perspectives and initial experiences of graduate radiographers on beginning their newly qualified roles.

Radiation Protection among South African Diagnostic Radiographers-A Mixed Method Study.

Worldwide, radiographers' radiation protection practices vary. In South Africa, evidence of diagnostic radiographers' suboptimal radiation protection practices has been reported, but the reasons for these practices and suggestions to improve practices were lacking. Therefore, this study explored radiation protection among South African diagnostic radiographers.

Collimation and cropping in diagnostic radiography: How concerned are we?

This editorial examines current collimation and cropping practices in general radiography. We critically reflect on whether we are concerned by the practice of collimation creep amongst radiographers. Discussions around policy, evidence‐based practice and potential hypocrisies are outlined in this editorial piece.

An exploratory study on recently qualified Australian radiographers' expectations and experiences in emergency and trauma imaging.

Background: Radiographers provide imaging services in multiple healthcare settings, including emergency and trauma. Transitioning to a qualified radiographer is already a time of vulnerability - with the increasing complexity and unpredictable nature of the emergency and trauma healthcare environment, recently qualified radiographers may experience this environment distinct from other service delivery areas.

Objective: The study explored recently qualified radiographers' expectations and experiences in emergency and trauma imaging service delivery.

The influence of patient positioning on radiation dose in CT imaging: A narrative review.

Background And Purpose: Although it is fundamental for optimal scanner operation, it is generally accepted that accurate patient centring cannot always be achieved. This review aimed to examine the reported knowledge of the negative impact of patient positioning on radiation dose and image quality during CT imaging. Furthermore, the study evaluated the current optimisation tools and techniques used to improve patient positioning relative to the gantry iso-center.

The Impacts of Vertical Off-Centring, Localiser Direction, Phantom Positioning and Tube Voltage on CT Number Accuracy: An Experimental Study.

Background: This study investigates the effects of vertical off-centring, localiser direction, tube voltage, and phantom positioning (supine and prone) on computed tomography (CT) numbers and radiation dose. Methods: An anthropomorphic phantom was scanned using a Discovery CT750 HD—128 slice (GE Healthcare) scanner at different tube voltages (80, 120, and 140 kVp). Images employing 0° and 180° localisers were acquired in supine and prone positions for each vertical off-centring (±100, ±60, and ±30 mm from the iso-centre).

The reliability of CT numbers as absolute values for diagnostic scanning, dental imaging, and radiation therapy simulation: A narrative review.

Background And Purpose: The purpose of this review was to examine the reported factors that affect the reliability of Computed Tomography (CT) numbers and their impact on clinical applications in diagnostic scanning, dental imaging, and radiation therapy dose calculation.

Methods: A comprehensive search of the literature was conducted using Medline (PubMed), Google Scholar, and Ovid databases which were searched using the keywords CT number variability, CT number accuracy and uniformity, tube voltage, patient positioning, patient off-centring, and size dependence. A narrative summary was used to compile the findings under the overarching theme.

Using the theory of planned behaviour to determine radiation protection among South African diagnostic radiographers: a cross-sectional survey.

Introduction: The use of ionising radiation in medicine accounts for the majority of radiation exposure from artificial sources. Therefore, all measures to safeguard against unnecessary radiation exposure must be taken. As radiographers are central to radiation protection, this study aimed to determine South African radiographers' attitude towards radiation protection, subjective norm and perceived behavioural control concerning radiation protection.

0° vs. 180° CT localiser: The effect of vertical off-centring, phantom positioning and tube voltage on dose optimisation in multidetector computed tomography.

Introduction: Patient positioning is an essential consideration for the optimisation of radiation dose during CT examinations. The study objectives seek to explore the effects of vertical off-centring, localiser direction (0° and 180°), and phantom positioning (supine and prone) on radiation dose, using three different tube voltages in multidetector computed tomography (MDCT) imaging.

Methods: The trunk of a PBU-60 anthropomorphic phantom was imaged using a Discovery CT750 HD - 128 slice (GE Healthcare).

A Survey Exploring Personalised Medicine amongst Radiography Academics within the United Kingdom.

Introduction: This article explores the application of personalized medicine (PM) within the academic environment in the United Kingdom. There is a growing acceptance of the utility of PM in health care and the role medical imaging can play. In response, this article explored the views and opinions of diagnostic and therapeutic academics and the utilization of PM in education.

Ethnographic mosaic approach for health and rehabilitation practitioners: an ethno-radiographic perspective.

This methodological commentary focuses on the use of ethnography for health and rehabilitation practitioners. In recent years, ethnography has become a methodology of choice amongst diagnostic radiography researchers at uncovering phenomena pertinent to the clinical setting. This paper adds to the evidence base by providing not only a methodology account from two experienced researchers, but also offers a paradigmatic approach to ethnography that incorporates qualitative and quantitative approaches.

Ethnography for Radiographers: A Methodological Insight for Prospective Researchers.

In recent years, ethnography has become a methodology of choice for exploring radiographic practices. This article adds to the existing evidence base by providing detailed methodological accounts of two experienced researchers. It aims to provide a critical methodological lens to prospective researchers who may also use ethnography as their methodology of choice.

The Use of Digital Side Markers (DSMs) and Cropping in Digital Radiography.

Introduction: This article explores two phenomena in the general radiography environment-the increasing use of digital side markers (DSMs) by radiographers and the possibility for radiographers to "crop" radiographs post-exposure. This article offers originality by identifying the rationales of radiographers when using digital equipment.

Methods: This study formed part of a larger ethnographic study undertaken in the United Kingdom (UK).

Personalised Medicine and Medical Imaging: Opportunities and Challenges for Contemporary Health Care.

This commentary offers a contemporary perspective on personalised medicine (PM) within diagnostic radiography. PM refers to the use of a person's genetic information in tailoring strategies for the detection, treatment, or prevention of disease. Some key issues are raised in light of this new specialty and how it may affect diagnostic imaging.
