Abstract: In paediatric imaging, it is common practice to hold children still for an examination by using immobilisation devices, parents, and/or staff. Historically, there has been a perceived need to restrain a child against their will when uncooperative behaviour was demonstrated. The issue of patient consent and use of physical force forms this fundamental difference between "immobilisation" and "restraint". To avoid unknowingly "restraining" a child, the factors affecting a radiographer's decision to "restrain" are explored in this literature review from a child's rights and radiation protection perspective. Literature searches were performed using the primary keywords "paediatric", "immobilisation", "restraint", and "medical imaging". Titles, abstracts, and full texts were screened for their relevance and resulted in 16 articles to address the aims of this literature review. The literature discussing immobilisation and restraint in paediatric imaging includes 16 articles published between 1980 and 2017. The literature findings were categorised, analysed, and discussed under the five subtopics: definitions of immobilisation and restraint, consent and children's rights, paediatric radiation protection, radiation dose to parents and staff, and the future implications of restraint in medical imaging. Many factors, including the justification of the examination, the rights of the child, the child's cooperative ability, and the radiation doses to the patient and accompanying persons, mean the decision to restrain may be a difficult one to make. The introduction of guidelines and training in Australia would prove useful in assisting this decision-making process. An in idual assessment of the child's best interests and family's needs must be considered however, restraint should ideally be avoided unless justified through a risk-benefit analysis.

Abstract: Effective operation of a microgrid depends critically on accurate forecasting of its components. Recently, internet forecasting competitions have been used to determine the best methods for energy forecasting, with some competitions having a special focus on microgrids and COVID-19 energy-use forecasting. This paper describes forecasting for the IEEE Computational Intelligence Society 3rd Technical Challenge, which required predicting solar and building loads of a microgrid system at Monash University for the month of November 2020. The forecast achieved the lowest error rate in the competition. We review the literature on recent energy forecasting competitions and metrics and explain how the solution drew from top-ranked solutions in previous energy forecasting competitions such as the Global Energy Forecasting Competition series. The techniques can be reapplied in other forecasting endeavours, while approaches to some of the time-series forecasting are more ad hoc and specific to the competition. Novel thresholding approaches were used to improve the quality of the input data. As the training and evaluation phase of the challenge occurred during COVID-19 lockdown and reopening, the building demand was subject to pandemic-related effects. Finally, we assess other data sources which would have improved the model forecast skill such as data from different numerical weather prediction (NWP) models, solar observations, and high-resolution price and demand data in the vicinity of the c us.

Abstract: A series of 31 radiographs is recommended by the Royal College of Radiologists (RCR) when investigating suspected physical abuse (SPA). To determine the radiation dose delivered for skeletal surveys performed for SPA in Victorian radiology departments based on their local protocols. A 5-year-old paediatric bone fracture phantom was radiographed at five radiology sites using both the RCR recommended protocol and, where applicable, the local departmental SPA protocol. The radiation doses were measured and recorded. These were scaled down to estimate the effective radiation doses for a 2-year-old child at each site and the associated radiation risks estimated. The median effective dose for all radiographic projections in the RCR skeletal survey radiographic series was 0.09 mSv. The estimated risk of radiation-induced cancer and radiation-induced death from cancer for 2-year-old children is classified as “very low,” with girls having a higher risk than boys. The median effective radiation dose for the RCR skeletal survey for imaging in SPA was 0.09 mSv resulting in a “very low” additional risk of radiation-induced cancer. The authors will now aim to ascertain whether whole-body CT skeletal survey can replace the radiographic series for imaging in SPA while maintaining a comparable radiation dose.

Abstract: Introduction: Diagnostic reference levels (DRLs) are typical dose levels for medical imaging examinations for groups of standard‐sized patients or standard phantoms for broadly defined types of equipment used as a tool to aid optimisation of protection for medical exposures. Currently, there are no paediatric DRLs for conventional radiography (i.e. general X‐rays) published in Australia. The aim of this study was to establish typical radiation doses and risks that are representative of those delivered for commonly performed X‐ray projections for a 5‐year‐old/20 kg child using a 5‐year‐old anthropomorphic ‘bone fracture’ phantom in three dedicated paediatric radiology departments in Victoria. Methods: A total of 20 projection images were acquired for a standard 5‐year‐old/20 kg phantom using digital radiography X‐ray equipment. The air kerma‐area product (KAP) measured at each centre by a KAP metre, which was calibrated to a national primary standard, was considered to represent the median value for that centre for each X‐ray projection. Organ doses and effective dose were estimated using PCXMC software, and risks of radiation‐induced cancer and radiation‐induced death were calculated based on the BEIR VII report. Results: The typical doses for the in idual X‐ray projections ranged from 3 mGy•cm 2 to 86 mGy•cm 2 , whilst the effective doses ranged from 0.00004 to 0.07 mSv. The radiation risks were ‘minimal’ to ‘negligible’. Conclusion: The estimation of typical radiation doses and associated risks for a 5‐year‐old/20 kg phantom study provides reference values for guidance and is a first step in assisting optimisation at other institutions until national DRLs, based on patient data from the clinical setting, are published.
