“…62 A more focused systematic review of AM for patient-specific surgical guides reviewed 38 publications, 59 while another study on patient-specific immobilization devices used in radiotherapy treatments found 18 articles. 63 Compared to these reviews of medical applications, where the average number of papers reviewed was 131, this broad systematic review of AM for sports applications with only 26 publications is significantly smaller than medical applications and reinforces comments by Mawale et al 9 that research into sports applications is only at the ''initiating phase'' compared to the more established medical industry.…”

Sport is an industry that may benefit from the opportunities offered by additive manufacturing (AM), and the media has portrayed increasing adoption of the technology in sports products. This systematic review aimed to consolidate and interpret the available empirical evidence concerning applications of AM in sports following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) 2015. Four databases were searched within the date range of January 1984 to May 2019, using 28 broad and specific search phrases. This search resulted in 26 articles for analysis, the first appearing in 2010. Twelve sports in total were identified across the literature, with running/walking the most popular sport with ten articles (38%) investigating AM, followed by cycling with four articles (15%) and badminton with three articles (12%). Ten articles (38%) observed improvements in performance of products developed via AM compared to conventionally manufactured products, eight articles (31%) found a similar performance, and five articles (19%) found a lower performance. From a technical perspective, powder bed fusion technologies were the most utilized with 50% of articles using either selective laser sintering (SLS) or selective laser melting (SLM), although 52% of articles did not name the 3D printer used and 36% did not name any software used to design or optimize products. 3D scanning technology was also utilized in 11 articles (42%). Results indicate that AM has been slow to permeate sports research, and while considered across a variety of potential applications, has largely resulted in singular studies with potentially limited opportunities or funding for follow-up investigations.

A Simulation-Based Methodology of Developing 3D Printed Anthropomorphic Phantoms for Microwave Imaging Systems

et al. 2021

This work is devoted to the development and manufacturing of realistic benchmark phantoms to evaluate the performance of microwave imaging devices. The 3D (3 dimensional) printed phantoms contain several cavities, designed to be filled with liquid solutions that mimic biological tissues in terms of complex permittivity over a wide frequency range. Numerical versions (stereolithography (STL) format files) of these phantoms were used to perform simulations to investigate experimental parameters. The purpose of this paper is two-fold. First, a general methodology for the development of a biological phantom is presented. Second, this approach is applied to the particular case of the experimental device developed by the Department of Electronics and Telecommunications at Politecnico di Torino (POLITO) that currently uses a homogeneous version of the head phantom considered in this paper. Numerical versions of the introduced inhomogeneous head phantoms were used to evaluate the effect of various parameters related to their development, such as the permittivity of the equivalent biological tissue, coupling medium, thickness and nature of the phantom walls, and number of compartments. To shed light on the effects of blood circulation on the recognition of a randomly shaped stroke, a numerical brain model including blood vessels was considered.

“…Customisation of immobilisation devices is very common, and patient-specific assessments may be required if new methods such as 3D printing are introduced. 51 It is important to note that positioning devices are usually in direct contact with the patient and as such they may require specific consideration as a medical device. In Australia, the Therapeutic Goods Administration (TGA) has recently provided update guidance on this issue (https://www.tga.gov.au/ medical-devices-reforms-personalised-medical-devices).…”

Quality management in radiotherapy treatment delivery

Radiation Oncology continues to rely on accurate delivery of radiation, in particular where patients can benefit from more modulated and hypofractioned treatments that can deliver higher dose to the target while optimising dose to normal structures. These deliveries are more complex, and the treatment units are more computerised, leading to a re-evaluation of quality assurance (QA) to test a larger range of options with more stringent criteria without becoming too time and resource consuming. This review explores how modern approaches of risk management and automation can be used to develop and maintain an effective and efficient QA programme. It considers various tools to control and guide radiation delivery including image guidance and motion management. Links with typical maintenance and repair activities are discussed, as well as patient-specific quality control activities. It is demonstrated that a quality management programme applied to treatment delivery can have an impact on individual patients but also on the quality of treatment techniques and future planning. Developing and customising a QA programme for treatment delivery is an important part of radiotherapy. Using modern multidisciplinary approaches can make this also a useful tool for department management.
