Interactive visualization of four-dimensional ultrasound data.
We present a hardware-accelerated method using three-dimensional (3D) textures to visualize four-dimensional (4D) images of the heart. Novel data subdivision and caching ideas enable interactive performance even though 4D data exceed the size of 3D texture memory. The capability to visualize 4D images is critical to continued evolution and clinical acceptance of 4D imaging.
