Purpose: The purpose of this study was to discuss the merits of using depth-sensing infrared camera technology in the brachytherapy operating room during interstitial brachytherapy for gynecologic malignancies.
Materials and methods: The infrared depth-sensing camera from a Microsoft Kinect that had been adapted for surgical use was introduced into a high-volume interstitial brachytherapy operating room. Brachytherapists then used the touchless, gestural interface to review preoperative MRI in real time to guide needle insertion.
Results: The interface was used for 10 consecutive procedures by 4 separate brachytherapists. The initial training and adjustment to the technology was variable among brachytherapists. All brachytherapists found the controls intuitive and were able to successfully navigate MRI on the system after 1, 30, 30, and 45 min. Qualitatively, brachytherapists found the system helpful for interpretation of intraoperative ultrasound imaging. Furthermore, it ensured adequate needle positioning and deposition was maintained for large tumors. Surgeons involved in its use agreed on potential for considerable benefit when performing interstitial brachytherapy.
Conclusions: Adapting this technology for use in the brachytherapy suite provided a higher level of comfort with interstitial catheter placement. This novel tool or similar technology might be considered within other brachytherapy suites.
