“…To thoroughly evaluate any systematic discrepancies in the dose comparisons pulled from literature would require a detailed comparison of technique and geometric parameters reported and stored by the system through either radiation dose structure reports (RDSRs) or controller area network (CANs). 20 Unfortunately, this level of detail was not available in the literature we found and does pose an additional limitation of this study. Although, as state previously, the literature we pulled represents many institutions, procedures, and physicians.…”

“…The quality of training for fluoroscopy system operators can play a large role in physician dose, particularly for C‐Arm procedures, given considerations for AEC response of the imaging system. To thoroughly evaluate any systematic discrepancies in the dose comparisons pulled from literature would require a detailed comparison of technique and geometric parameters reported and stored by the system through either radiation dose structure reports (RDSRs) or controller area network (CANs) 20 . Unfortunately, this level of detail was not available in the literature we found and does pose an additional limitation of this study.…”

PurposeTo quantify operator dose in interventional CT fluoroscopy (CTF) procedures and compare to catheterization laboratory and interventional radiology procedures.MethodsFifteen studies quantifying operator scatter dose for c‐arm fluoroscopy and CTF were reviewed from a literature survey. The dose provided in each study was normalized to skin entrance air kerma and air kerma rate including backscatter. The average air kerma rate and exposure duration were calculated and compared between c‐arm fluoroscopy and CTF. To enable operator scatter dose calculations in CTF procedures, a model was created which scaled the dose from a reference condition.ResultsOur literature survey indicated that for CTF relative to c‐arm fluoroscopy: (1) the mean air kerma rate is 3.5 times higher, while (2) the mean exposure duration is 31.6 times lower. On average, a physician would have to perform 9.1 times (i.e., 31.6/3.5) more CTF procedures relative to c‐arm fluoroscopy procedure to receive equal operator scatter doses. Our own experimental measurements provided scaling factors allowing physician scatter dose to be obtained at any rotation time, tube current, beam collimation, or beam energy.ConclusionOur results shed light onto a currently mis‐understood issue in radiology. Namely, that physicians receive more dose from CT relative to c‐arm fluoroscopy motivating them to retreat from the room during interventional exposures. Our literature review and experimental measurements indicate the opposite it true; interventional CT produces on average nine times less physician dose relative to c‐arm procedures. Our method allows for prospective/retrospective determination of an individual's dose.

“…In procedures using ionizing radiation, one of the most valuable assets that ER provides is minimizing the doses used during procedures [ 24 , 25 , 55 , 56 , 57 , 58 , 59 , 60 ], with benefits to the patients and the staff. On the other hand, evaluating the cost-effectiveness of VR and AR in medical education is a crucial question when analyzing these technologies.…”

“…Currently, this research area has yet to be fully explored. Further research in this area will modernize diagnostic procedures and improve healthcare by creating new techniques and tools that can be used in clinical practice [ 58 , 59 , 60 , 61 ]. In conclusion, virtual and augmented reality technologies have the potential to transform medical education and patient care in diagnostic imaging.…”

The utilization of extended reality (ER) has been increasingly explored in the medical field over the past ten years. A comprehensive analysis of scientific publications was conducted to assess the applications of ER in the field of diagnostic imaging, including ultrasound, interventional radiology, and computed tomography. The study also evaluated the use of ER in patient positioning and medical education. Additionally, we explored the potential of ER as a replacement for anesthesia and sedation during examinations. The use of ER technologies in medical education has received increased attention in recent years. This technology allows for a more interactive and engaging educational experience, particularly in anatomy and patient positioning, although the question may be asked: is the technology and maintenance cost worth the investment? The results of the analyzed studies suggest that implementing augmented reality in clinical practice is a positive phenomenon that expands the diagnostic capabilities of imaging studies, education, and positioning. The results suggest that ER has significant potential to improve diagnostic imaging procedures’ accuracy and efficiency and enhance the patient experience through increased visualization and understanding of medical conditions. Despite these promising advancements, further research is needed to fully realize the potential of ER in the medical field and to address the challenges and limitations associated with its integration into clinical practice.
