  Interactive photorealistic rendering of 3D anatomy is used in medical
education to explain the structure of the human body. It is currently
restricted to frontal teaching scenarios, where even with a powerful GPU and
high-speed access to a large storage device where the data set is hosted,
interactive demonstrations can hardly be achieved. We present the use of novel
view synthesis via compressed 3D Gaussian Splatting (3DGS) to overcome this
restriction, and to even enable students to perform cinematic anatomy on
lightweight and mobile devices. Our proposed pipeline first finds a set of
camera poses that captures all potentially seen structures in the data.
High-quality images are then generated with path tracing and converted into a
compact 3DGS representation, consuming < 70 MB even for data sets of multiple
GBs. This allows for real-time photorealistic novel view synthesis that
recovers structures up to the voxel resolution and is almost indistinguishable
from the path-traced images
