ACR Low-Contrast Object Detectability Task #450

Open abdrysdale opened 1 month ago

abdrysdale commented 1 month ago

As per section 7 of the Large and Medium Phantom Test Guidance for the ACR MRI Accreditation Program; the low contrast detectability test assesses the extent to which objects of low contrast are discernible in the images.

These are performed on slices 8 through 11 by counting the number of visible spokes.

To my knowledge this doesn't seem to be available in Hazen - would it be possible to add this task?

I don't mind writing the tests for this myself and submitting a pull request if there aren't the resources to add this task in-house.

Here is an example of slice 10 taken from the ACR Phantom Manual to illustrate the test:
