Abstract
Brachytherapy is an efficient clinical treatment way for cervical cancer, which is one of the most common gynecological malignancies. Traditional manual cervical tumor segmentation is a massive and time-consuming task, and we tend to enhance the manual segmentation efficiency. In this study, we present a novel virtual reality environment that supports cervical tumor 3D segmentation using user hands and spatial pan. We created a cervical imaging visualization platform, included the 2D and 3D medical image display and an interactive plane that connects 2D and 3D medical images. Furthermore, we proposed a 3D spatial interaction method that combines free-hand interaction with an optical localization-based interactive pen, which is both convenient and efficient. We built a prototype and verified the feasibility of the proposed environment through user research. Our prototype was well received by the participants, and the average tumor segmentation time was around 5 min. We hope to improve our environment in future.
