Abstract
Augmented reality (AR) projects additional information into the user's field of view during interventions. The aim was to evaluate the acceptance and clinical feasibility of an AR system and to compare users with different levels of experience. A system was examined that projects a CT-generated 3D model of a phantom into the field of view using a HoloLens 2, whereby the tracked needle is displayed and navigated live. A projected ultrasound image is used for live control of the needle positioning. This should minimize radiation exposure and improve orientation.The acceptance and usability of the AR navigation system was evaluated by 10 physicians and medical students with different levels of experience by performing punctures with the system in a phantom. The required time was then compared and a questionnaire was completed to assess clinical acceptance and feasibility. For statistical analysis, frequencies for qualitative characteristics, location and dispersion measures for quantitative characteristics and Spearman rank correlations for correlations were calculated.9 out of 10 subjects hit all 5 target regions in the first attempt, taking an average of 29:39 minutes for all punctures. There was a significant correlation between previous experience in interventional radiology, years in the profession, and the time required. Overall, the time varied from an average of 43:00 min. for medical students to 15:00 min. for chief physicians. All test subjects showed high acceptance of the system and rated especially the potential clinical feasibility, the simplification of the puncture, and the image quality positively. However, the majority require further training for sufficient safety in use.The system offers distinct advantages for navigation and orientation, facilitates percutaneous interventions during training and enables professionally experienced physicians to achieve short intervention times. In addition, the system improves ergonomics during the procedure by making important information always directly available in the field of view and has the potential to reduce the radiation exposure of staff in particular by combining AR and sonography and thus shortening CT-fluoroscopy times. · AR navigation offers advantages for orientation during percutaneous radiological interventions.. · The subjects would like to use the AR system in everyday clinical practice on patients.. · AR improves ergonomics by making important information directly available in the field of view.. · The combination of AR and sonography can significantly reduce radiation exposure for staff.. · Rohmer K, Becker M, Georgiades M et al.

增强现实（AR）可在干预过程中将额外信息投射到用户视野中。目的是评估 AR 系统的接受度和临床可行性，并对不同经验水平的用户进行比较。该系统使用 HoloLens 2 将 CT 生成的三维模型投射到视野中，从而实时显示和导航追踪的针头。投射的超声图像用于实时控制针的定位。10 名具有不同经验水平的医生和医科学生通过在模型中使用该系统进行穿刺，对 AR 导航系统的接受度和可用性进行了评估。然后对所需时间进行了比较，并填写了一份调查问卷，以评估临床接受度和可行性。在统计分析中，计算了定性特征的频率、定量特征的位置和离散度量以及相关性的斯皮尔曼等级相关性。介入放射学经验、从业年限与所需时间之间存在明显的相关性。总体而言，所需时间从医学生的平均 43 分钟到主任医师的 15 分钟不等。所有测试对象对该系统的接受度都很高，尤其对其潜在的临床可行性、穿刺的简化程度和图像质量给予了积极评价。该系统在导航和定位方面具有明显的优势，便于在培训期间进行经皮介入治疗，并使有专业经验的医生能够缩短介入治疗时间。此外，该系统还能在手术过程中直接显示重要信息，从而改善人体工程学，尤其是通过将 AR 和超声波检查结合起来，缩短 CT-荧光透视检查时间，有可能减少工作人员的辐射暴露。- AR 导航在经皮放射介入过程中的定位方面具有优势。- 受试者希望在日常临床实践中对病人使用 AR 系统。- AR可在视野中直接显示重要信息，从而提高了人体工程学。- AR与超声造影术的结合可显著减少工作人员的辐射暴露。- Rohmer K, Becker M, Georgiades M 等人.基于增强现实技术的导航系统在介入放射学经皮手术中的接受度和可行性--基于模拟的模型研究。Fortschr Röntgenstr 2024; DOI 10.1055/a-2416-1080.
期刊介绍：
Die RöFo veröffentlicht Originalarbeiten, Übersichtsartikel und Fallberichte aus dem Bereich der Radiologie und den weiteren bildgebenden Verfahren in der Medizin. Es dürfen nur Arbeiten eingereicht werden, die noch nicht veröffentlicht sind und die auch nicht gleichzeitig einer anderen Zeitschrift zur Veröffentlichung angeboten wurden. Alle eingereichten Beiträge unterliegen einer sorgfältigen fachlichen Begutachtung.
Gegründet 1896 – nur knapp 1 Jahr nach der Entdeckung der Röntgenstrahlen durch C.W. Röntgen – blickt die RöFo auf über 100 Jahre Erfahrung als wichtigstes Publikationsmedium in der deutschsprachigen Radiologie zurück. Sie ist damit die älteste radiologische Fachzeitschrift und schafft es erfolgreich, lange Kontinuität mit dem Anspruch an wissenschaftliches Publizieren auf internationalem Niveau zu verbinden. Durch ihren zentralen Platz im Verlagsprogramm stellte die RöFo die Basis für das heute umfassende und erfolgreiche Radiologie-Medienangebot im Georg Thieme Verlag.
Besonders eng verbunden ist die RöFo mit der Geschichte der Röntgengesellschaften in Deutschland und Österreich. Sie ist offizielles Organ von DRG und ÖRG und die Mitglieder der Fachgesellschaften erhalten die Zeitschrift im Rahmen ihrer Mitgliedschaft. Mit ihrem wissenschaftlichen Kernteil und dem eigenen Mitteilungsteil der Fachgesellschaften bietet die RöFo Monat für Monat ein Forum für den Austausch von Inhalten und Botschaften der radiologischen Community im deutschsprachigen Raum.
