Which of the following is false about volume rendering?

a Volume rendering does not require prior tissue segmentation, unlike surface rendering.

b Volume rendering requires a means of aggregating tissue properties along a sampled path that is orthogonal to the image plane and pierces it at the pixel of interest.

c One strategy for aggregating tissue properties is Maximum Intensity Projection, which assigns the largest tissue voxel value (e.g. Hounsfield unit in CT), along the path, to the image pixel.

d In splatting, every voxel of the image volume is splatted like a snowball onto the viewing surface in front-to-back order.

e None of these statements is false.
