Segmentation was done first with an interactive software (Mialab), followed by manual inspection and correction using ITKSNAP. The interactive method is based on fuzzy connectedness followed by level set method. Both the segmentation mask and annotated anatomical landmarks were created by a trained radiologist.
DICOM. Please see our help pages for some examples of working with DICOM.
Importing binary masks to numpy
The dataset contains a DICOM SEG file, which can be converted to an ITK image file (mha, nifti, etc) by using dcmqi and the command line tool segimage2itkimage, which is straightforward to read into a numpy array.
Landmarks are available in the sr.dcm file and saved using the TID 1500 template.

Subject: Requesting access to dataset doi:10.23698/aida/ctpel
I work at INSTITUTION department of DEPARTMENT in COUNTRY, emailing from my institutional account.
I would like to request access to the dataset doi:10.23698/aida/ctpel, for use in research or education.
Our planned use of the data can be summarized as:
Also, I would like to ALTERNATIVELY_WOULD_NOT_LIKE_TO be included in the public record of data sharing facilitated by AIDA:
which is used to facilitate scientific discussion, and to show what good AIDA has been to the global research community.
(If "not", then only the institution/department information will be included. This choice of personal participation is not weighed into the access request eligibility evaluation.)
