My research interests include mixed reality based volume rendering and interactions focused on 3D cardiac ultrasound data. Currently my work focuses on real time global illumination with dynamic lights in mixed reality using Monte Carlo based rendering techniques. In this context, the ultrasound data is treated as participating media with multiple scattering rendering model using path tracing. The challenge with monte carlo methods is that they need many samples ( example images below ) to generate a clean image (noise free) which cannot be achieved in real-time. My work aims to take advantage of properties of ultrasound cardiac data combined with advanced sampling techniques and saptio-temporal reuse to generate renderings.
