“…Future work therefore requires a more rigorous quantification of the improvements such as informativeness of the visualization, measured radiation exposure, and perceived improvement in workflow in the mentioned application scenarios. For instance, the subjective quality of perception could be evaluated using the Maryland Visual Comfort Scale 34 . The usefulness of VR/MR technologies should also be contrasted with psychological research on the concept of presence MR 35 to elucidate why they are useful, thereby potentially aiding in the guided ideation for future applications of MR technologies.…”

Radiation source localization and characterization are challenging tasks that currently require complex analyses for interpretation. Mixed reality (MR) technologies are at the verge of wide scale adoption and can assist in the visualization of complex data. Herein, we demonstrate real-time visualization of gamma ray and neutron radiation detector data in MR using the Microsoft HoloLens 2 smart glasses, significantly reducing user interpretation burden. Radiation imaging systems typically use double-scatter events of gamma rays or fast neutrons to reconstruct the incidence directional information, thus enabling source localization. The calculated images and estimated ’hot spots’ are then often displayed in 2D angular space projections on screens. By combining a state-of-the-art dual particle imaging system with HoloLens 2, we propose to display the data directly to the user via the head-mounted MR smart glasses, presenting the directional information as an overlay to the user’s 3D visual experience. We describe an open source implementation using efficient data transfer, image calculation, and 3D engine. We thereby demonstrate for the first time a real-time user experience to display fast neutron or gamma ray images from various radioactive sources set around the detector. We also introduce an alternative source search mode for situations of low event rates using a neural network and simulation based training data to provide a fast estimation of the source’s angular direction. Using MR for radiation detection provides a more intuitive perception of radioactivity and can be applied in routine radiation monitoring, education & training, emergency scenarios, or inspections.

“…It would also be useful to validate our results with a larger group of scope operators and offsite reviewers. Whereas the Likert scale utilized in this study is not specifically validated for display quality, several studies have used similar optical characteristics and scaled grading to analyze optical data . As with any technology, subsequent adaptor models and devices made by competing manufacturers may differ in their clinical utility and features.…”

Objective To determine whether a smartphone adaptor can record laryngoscopic videos of adequate quality for clinical diagnosis and communication among otolaryngologists and assess the impact of recorded exams on patient satisfaction. Methods Twenty adult inpatients undergoing flexible laryngoscopy in a tertiary care medical center were prospectively enrolled. Each subject's larynx was visualized with the standard laryngoscope eyepiece and with an attached mobile phone adaptor with video recording capabilities. A 5‐point Likert scale was used by the resident performing the scope to grade the adaptor and eyepiece exams. The same scale was used by an offsite otolaryngology attending to grade the adaptor video. Patients were shown the video, and a satisfaction survey was administered. Results In all patients, the adaptor was easy to use and required minimal setup. Ninety percent of patients reported an increase in satisfaction after watching the video of their exam. The eyepiece was superior to the adaptor in resolution, focus, color fidelity, brightness, and optical fluidity (P < 0.05). The video recording was deemed sufficient for clinical assessment in 90% of cases. The offsite reviewer determined that there would be “little” (15%) or “no value” (65%) in repeating the scope exam in the majority of patients. The laryngeal subsites were equally visible with the eyepiece and the adaptor (“full view,” 85%–100%). Conclusion Laryngoscopy videos recorded by a portable smartphone adaptor are sufficient for clinical evaluation in the majority of cases. This technology may improve patient satisfaction and communication among clinicians. Level of Evidence 4 Laryngoscope, 129:2147–2152, 2019

“…One of the most studied ergonomic models is the surgeon performing laparoscopic surgery [31,32]. Current literature explores ergonomic concepts such as optimal bed height, monitor placement, adjustable screen heights, screen sizes, image quality and standing mat technology, which have been associated with improved provider comfort [33][34][35][36][37][38][39][40].…”

Interventional pulmonologists require a unique set of skills including precise motor abilities and physical endurance, but surprisingly the application of ergonomic principles in the field of bronchoscopy remains limited. This is particularly intriguing when considering the significant impact that poor ergonomics can have on diagnostic aptitude, income potential and overall health. It is therefore imperative to provide comprehensive education to physicians regarding the significance of ergonomics in their work, especially considering the introduction of advanced diagnostic and therapeutic procedures. By implementing simple yet effective measures (e.g.maintaining neutral positions of the wrist, neck and shoulder; adjusting the height of tables and monitors; incorporating scheduled breaks; and engaging in regular exercises), the risk of injuries can be substantially reduced. Moreover, objective tools are readily available to assess ergonomic postures and estimate the likelihood of work-related musculoskeletal injuries. This review aims to evaluate the current literature on the impact of procedure-related musculoskeletal pain on practising pulmonologists and identify modifiable factors for future research.
