Impact of Audio-Visual Assisted Therapeutic Ambience in Radiotherapy (AVATAR) on Anesthesia Use, Cost, and Time in Pediatric Patients

Abstract

in the lower extremities, 5% to 16% in the ribs, 4% to 10% in the upper extremities, 1% to 5% in the scapulae, and 1% to 4% in the sternum & clavicles. A gradual shift of RBM towards the central skeleton occurred with aging. Compared to our measured data, the mathematical model underestimated the %RBM in the cranium & mandible and the sternum & clavicles. However, the model overestimated the %RBM in the upper extremities, the ribs, and the pelvis & vertebrae. Trends and rates of change in %RBM for these sites were consistent between our measured data and the mathematical model. Finally, although our %RBM values were similar to those of the mathematical model for the lower extremities and scapulae, the trends and rates of change differed. Conclusion: In most sub-volumes, distributions of RBM in children measured in our study slightly differed from those estimated by the most commonly accepted mathematical model. Despite the limited number of subjects for this study, we were able to validate or find inconsistencies between measured and modeled trends and rates of RBM changes with age. Further studies of high-resolution pTB-MRI should be performed for a broader spectrum of ages as high-efficiency pTB-MRI acquisition becomes manageable. These measured data will be important for aiding clinicians to consider the risk of secondary hematological malignancies in pediatric radiation therapy survivors.

“…In addition, the iPhone ® was connected to a preexisting clinical radiolucent audio-visual (AVATAR) system, 15,16 shown in Fig. 1(d) (phantom) and Figs.…”

“…In the present work, a real-time position monitoring system, coined the Instant Respiratory Feedback (IRF) system, that leverages accurate motion related data from onboard hardware in Apple iOS devices is developed and evaluated. The IRF system was also integrated into a current clinical audiovisual-assisted therapeutic ambience in radiation therapy (AVA-TAR) system 15,16 and evaluated its ability to measure surface motion by comparing it to a commercial system.…”
