TOGS: Gaussian Splatting with Temporal Opacity Offset for Real-Time 4D DSA Rendering

arXiv:2403.19586v1 Announce Type: new
Abstract: Four-dimensional Digital Subtraction Angiography (4D DSA) is a medical imaging technique that provides a series of 2D images captured at different stages and angles during the process of contrast agent filling blood vessels. It plays a significant role in the diagnosis of cerebrovascular diseases. Improving the rendering quality and speed under sparse sampling is important for observing the status and location of lesions. The current methods exhibit inadequate rendering quality in sparse views and suffer …
