Visualization of 3D ultrasound uterine data in virtual reality

Gavrilović, Ilija (author), Bohak, Ciril (author)

Virtual reality (VR) has emerged as a powerful medium for medical imaging visualization and training, ofering immersive and interactive experiences that complement conventional two-dimensional (2D) imaging worklows. In gynecology, ultrasound (US) is the primary imaging modality for assessing uterine morphology, yet its interpretation requires signiicant spatial reasoning and is challenging for trainees with limited clinical exposure. This paper presents a standalone VR system for interactive visualization of uterine US volumes, designed for deployment on Meta Quest 2. The system integrates three core components: (i) textured surface meshes mapped directly from US intensity values, (ii) per-vertex deviation heatmaps comparing individual anatomy to a population-average uterus, and (iii) orthogonal slice browsing with adjustable transfer functions and lookup tables. The system is developed in Unity for immersive rendering. Preliminary demonstrations indicate that providing outside- and inside-based views improves spatial understanding and provides educational value by contextualizing individual variability. Performance proiling conirms real-time rendering on standalone hardware, ensuring luid interaction without tethered computing resources. By unifying segmentation-driven shape analysis with immersive visualization, this work highlights the potential of lightweight VR applications to enhance gynecological training and provide accessible platforms for medical education and research.
