Fractional Segmentations

[lluisb3]

Hi,

First of all thanks for this impressive work. Papaya looks promising as a 3d medical image viewer. I am choosing a viewer for my application and I am undecided, my 2 options right now are OHIF Viewer and Papaya.

One important utility for me is to be able to load Fractional segmentations (with continuous data), does Papaya allow this? I checked and in OHIF only Binary segmentations are available at the moment if I am not wrong and discretization of the data is needed to allow loading a fractional segmentation. This would be a good point to go for Papaya.

Thanks in advance!

Hi @lluisb3 ,

I have started working on segmentation for papaya but drop the idea because of the workload I have. I will try to implement segmentation with binary as well as fractional but it will take time and precision. I will suggest you to go with OHIF as it has at least some thing implemented or share me what exactly you are looking for so that I can start analyzing on same if you are considering papaya only.

Hi @niks2060 ,

Thanks for your answer!

I was attracted by Papaya as allows me to visualize NIFTI images directly, avoiding the conversion from NIFTI to DICOM as needed in OHIF. The features I would like to have in the viewer are:

• To have the image and different overlays that can be easily switched for visualization. Binary segmentations (labels for different Multiple Sclerosis classes), and fractional segmentations (heatmaps, and trust scores).
• Be able to modify the segmentations because they are obtained from an automatic model and a doctor may want to correct them and output this modified segmentation file for future inferences.
• Navigate easily through the different lesions. As multiple lesions from different classes would be present.

I understand are many features. I just wanted to be sure if this was already available in Papaya, if not may be better for me to go with OHIF.
