Crop to match

[kenrickschulze]

Hey Community,

is there a MONAI transform like ResampleToMatchd but for cropping?

Lets say i have two volumes and one is just a small patch within the bigger volume. As both volumes have center and spacing coordinates, is there a monai transform to overlap both images in pixelspace by cropping the bigger volume to the field of view of the smaller one.

Best wishes :)

Hi @kenrickschulze, thanks for your interest here.

At present, we don't offer support for the "crop to match" operation. However, you could use the SpatialCrop which admits an "roi_center" parameter. By using "roi_center", you can specify the center for cropping your data.

MONAI/monai/transforms/croppad/array.py

Line 462 in ec63e06

roi_center: Sequence[int] | NdarrayOrTensor | None = None,

Hope it helps, thanks.
