How to display DICOM RT structure

Hello everyone,
I have some DICOM files with RS structure such as GTV and PTV from radiation therapy planning.
Then, I want to display it as a volume. First, I have done with 'dicominfo' to take any information and looking at GTV contour already.
I have seen the data with how many slice and others, but I don't know how to display. Just only one slice with coordinate is OK.
please help
Sandra

Perhaps https://www.mathworks.com/matlabcentral/answers/120098-how-to-read-dicom-rt-structure#answer_127021 would help read the files.

In my current project I'm reading RT-structures, transforming them into a nwe fram of reference and distort them. Here's some of my code for reading the RT-structures and displaying them using the plot3 command.
matlabFolder = pwd;
MyDirInfo=dir(pathway to your file); % Ex. 'C:\username\documents\....\rtstructure.dcm'
cd('C:\username\documents\....\rtstructurefolder')
info=dicominfo(MyDirInfo(1).name);
cd(matlabFolder)
structures=fieldnames(info.ROIContourSequence); %Lists all the structures
num_cont=size(structures,1); %Says how many it is
for n=1:num_cont %Loops through all structures
curr_struct=structures{n};
%Lists all the ROI-layers within a structure
ROIlayers=fieldnames(info.ROIContourSequence.(curr_struct).ContourSequence);
num_layers=size(ROIlayers,1);
for i=1:num_layers %Går igenom alla lager och hämtar deras positioner
currROIlayer=ROIlayers{i};
item_pos=info.ROIContourSequence.(curr_struct).ContourSequence.(currROIlayer).ContourData;
item_pos=reshape(item_pos, [3 length(item_pos)/3]);
item_pos_all=[item_pos_all, item_pos];
end
figure(n)
hold on
plot3(item_pos_all(1,:), item_pos_all(2,:), item_pos_all(3,:))
end
