Make Certain Dataset Fields Optional

[awtkns]

Opened from a comment on blog post.

PatientAge is optional information. It seems the utils requires PatientAge.

I have a CT dataset that has no PatientAge. The code would be crashed.

Traceback (most recent call last):
File “convert_nifti_segments_2_dicom.py”, line 6, in
rtstruct = RTStructBuilder.create_new(dicom_series_path=”./chest_CT”)

Is it possible to make PatientAge as an optional?
