I don't know much about nibabel and dicom but the KvikIO usage looks good!

Only suggestion I have is to include some information about the thread pool size. E.g., maybe show how to change the number of threads KvikIO uses: https://docs.rapids.ai/api/kvikio/nightly/runtime_settings/#thread-pool-kvikio-nthreads.
By default, KvikIO only uses 1 thread but often more threads improve performance (16-32 threads seems to be a good option in many cases).

kvikio.defaults.num_threads_reset(nthreads=16)
