Description

Describe the bug Running LoadImage(reader="ITKReader") without itk installed will just warn that itk is not installed and will proceed with using PILReader instead.

https://github.com/Project-MONAI/MONAI/blob/33afaefff925dce45b8331e8290f234a4d95fd51/monai/transforms/io/array.py#L185

Expected behavior If the specified reader is not installed, an exception should be raised.

Contributor guide

Research direction
Inspect the LoadImage function in monai/transforms/io/array.py around line 185, and modify the logic to raise an ImportError or RuntimeError when the specified reader is not installed instead of falling back to PILReader.
