Pilot study to determine if there is a radiation protection value from augmented reality smart glasses in interventional fluoroscopy procedures
S. Dorey1, L. Gray1, A. K. Tootell1, R. Higgins1, S. Al-Islam2, H. Baxter3, P. Hogg1; 1Salford/UK 2Blackburn/UK 3Manchester/UK

Aims and objectives:
Advancement in portable information and telecommunication technology has progressed at an incredible rate. The introduction of smart glasses such as Google Glass [1] (Figure 1), a device that can be worn like conventional glasses, whilst also incorporating a computerised central processing unit, int[...]
Methods and materials:
Data acquisition: A Ultimax-i Toshiba Fluoroscopy machine was used for imaging. An anthropomorphic phantom was utilised to simulate the patient, representing comparable absorption and scattering characteristics of human tissue (RSD Anthropomorphic Pelvis Phantom (RS-113T)). The phantom was positione[...]
Results:
Figure 7. shows a comparison between the average TLD dose readings around the simulated clinicians eyes for the varying head positions A – E at a normal head alignment (as represented in Figure 4). A reduction in eye dose was greatest when the simulated clinicians gaze was at a horizontal direction [...]
Conclusion:
A significant reduction in dose to clinician’s eye is received when looking directly at the scattering source. A new standard of practise can therefore be introduced whilst wearing smart glasses eliminating the need for the clinician to look at fixed position computer monitors during exposures. By i[...]

Image artefacts found on mobile chest imaging on transition to wireless digital cassettes. Experimentation to show cause of these artefacts and techniques to remove them
G. R. Ison1, D. W. Glenn2, M. Fitzgerald1, T. Dillon1, M. Klees1, S. So1, C. Pugh1, G. Tan1, C.-L. Kuo1; 1Sydney/AU 2Kogarah/AU

Learning objectives:
Rectangular image artifacts were noted on a few cases of AP chest radiographs performed using new high sensitivity digital wireless cassettes. These artifacts were accentuated in patients of larger body habitus where elevated kVPs were utilised. Possible parameters our research team considered in[...]
Background:
On moving to new high sensitivity wireless digital radiography cassettes, multiple low contrast rectangular shaped image artefacts have been found in AP chest radiographs especially in patients of larger body habitus where high kVPs were utilised. Collimation of the image can reduce how conspicuou[...]
Findings and procedure details:
To demonstrate these image artefacts, we endeavoured to visually enhance them by using 18cm of Perspex as a patient phantom. This allowed us to create similar real case beam energy and backscatter but a constant grey scale image, enabling visual amplification of the artefacts. The resultant image [...]
Conclusion:
Unlike film or CR cassettes, modern wireless digital cassettes have circuitry and a battery on the rear of the cassette. This dense componentry can create a differential absorption of backscatter to the front detector layer causing multiple regular shaped image artefacts. These artefacts are especi[...]

A survey to establish the methods used to appraise exposure in digital images by Irish radiographers
E. Broderick, K. Matthews; Dublin/IE

Aims and objectives:
Previous authors have discussed the absence of visual feedback on appropriate exposure with direct digital radiography (DDR) and computed radiography (CR) [1-7]. The concept of radiographic density that existed with film screen systems no longer has relevance. Instead, a numerical indication of expo[...]
Methods and materials:
Design An online image-based survey was developed using commercial survey software which provided Secure Socket Layer (SSL) security and encryption of transmitted data. No personal data were gathered. The study had institutional ethical approval. Questionnaire The questionnaire focussed on chest r[...]
Results:
Participant demographics Within the 85% response rate, respondents had a broad range of career experience (Fig. 5), were working across all areas of the imaging department and were familiar with one or more of Siemens, Philips, Agfa and GE CR/DDR equipment. Responses Respondents' opinions were c[...]
Conclusion:
The current study has tested five hypotheses by surveying a representative sample of Irish radiographers. The careful sampling and high response rate lead the authors to propose that the results can be generalised to the current population of radiographers working in Ireland. The conclusions are: [...]

Application of Digital Tomosynthesis (DTS) in the diagnosis of scaphoid fractures - a review of current research.
E. Carroll1, A. Robertson2; 1Aberdeen/UK 2Dublin/IE

Learning objectives:
To investigate the effectiveness of Digital Tomosynthesis (DTS) in the detection of scaphoid injuries when compared with Computed Tomography (CT) and general X-ray.
Background:
Background: Traditionally described as a single joint, the wrist is comprised with complex articulations between each of the carpal bones and metacarpals. Within the wrist, the scaphoid plays a crucial role in wrist function, linking the proximal and distal carpal rows of the wrist. This carpal bo[...]
Findings and procedure details:
Search Strategy: An initial literature search was performed using the databases Sciencedirect, PubMed and Google Scholar using keywords including “tomosynthesis” and “scaphoid”, as well as “digital scaphoid tomosynthesis”. Boolean terms were used to further refine results. References from releva[...]
Conclusion:
Considerations for the future: General x-ray remains the standard initial imaging technique of suspected acute scaphoid fractures. Despite the evidence available, it remains difficult to suggest that DTS could indeed become an alternative to CT where MRI is not available. It is evident that there [...]

A Survey of Radiography Educator Opinions about Patient Lead Shielding during Projection Radiography
C. Shanley, K. Matthews; Dublin/IE

Aims and objectives:
The background to the research is summarised in Fig. 1 In projection radiography, lead rubber aprons and shielding (all termed lead shielding in this poster) are applied both within and outside the collimated field [1]. Opinions on the efficacy and necessity of such shielding vary in peer review[...]
Methods and materials:
The methodological process is summarised in Fig. 2 Strategy An online questionnaire was designed in commercial software (Survey Monkey ®) and distributed to a purposive sample of 44 radiography educators across 15 countries. No personal data were gathered. The study had institutional ethical appro[...]
Results:
The response rate was 61% (27 of 44 invited participants), with 24 participants providing geographic information as presented in Table 1. All respondents had worked as a clinical radiographer during their career, 74% (n=20) had been teaching for more than five years. Most respondents (65%, n=18) w[...]
Conclusion:
Conclusions and recommendations are summarised in Fig. 5. Conclusions The mixed opinions found in literature concerning the use of lead shielding are replicated in the educator opinions and teaching reported in the current survey. Most educators acknowledge that tissue radio-sensitivity should in[...]
