Task:

Load the Aneurism dataset from "aneurism/data/aneurism_256x256x256_uint8.raw", the information about this dataset:
Aneurism
Description: Rotational C-arm x-ray scan of the arteries of the right half of a human head. A contrast agent was injected into the blood and an aneurism is present.
Data Type: uint8
Data Byte Order: little Endian
Data Spacing: 1x1x1
Data Extent: 256x256x256
Data loading is very important, make sure you correctly load the dataset according to their features.

Visualize the blood vessels using:
1. Apply volume rendering with a transfer function that highlights the contrast-enhanced vessels
2. Use a red-to-white color map for blood vessels
3. Extract an isosurface at a value that clearly shows the aneurism or vessel structure (experiment with values around 100-150)
4. Adjust opacity to make internal structures visible (opacity around 0.6-0.8 for vessels)

Please think step by step and make sure to fulfill all the visualization goals mentioned above.

Finally, save the paraview state as "aneurism/results/aneurism.pvsm"
