suggestion to avoid issue when multiple types of files are in the same folder

[EmmaSkarsoe]

Hi rt_Utils authors,

Thanks for a great tool !

I've experienced some problems, when I am running the add_roi function.
I got the following error-message: Mask must have the same number of layers (In the 3rd dimension) as input series. Expected 130, got 129.

The problem arises, because my folder contains both RT structs, CT scans, RT dose and RT plan. The RT dose file do also have a 'pixel_array' attribute.

I changed a line in the function: load_dcm_images_from_path

from
if hasattr(ds, "pixel_array"):
series_data.append(ds)
to
if ds.Modality == 'CT':
series_data.append(ds)

It solved my problem. :)

This is a really good idea! Perhaps instead of hardcoding it to "CT", there could be an option which defaults to CT, but is changable to other modalities. It could even be set with SOPClassUID to avoid overlapping uses of Modality?

Thanks for reaching out @EmmaSkarsoe, and good call @mathiser. I'm not sure when I can work on that but that seems like a good solution.
