This task is closed since the ModelFit/Perfusion views will be part of MITK v2024.06 and it is planned that they will be part of the official releases from MITK v2024.06 onwards.

In the MitkNodePredicateGeometry to precision is set to 1e-6. So this is at least one of the issues why the old masks are not found. It could be an option to relax the precision, but since the rotation matrix might have a large effect even for small inaccuracies, it needs to be thoroughly tested first how big the effect is if. e.g 1e-4 is accepted.
For now, the new segmentation masks are provided as test data instead of the old masks.

I compared the geometry of the dynamic image, the old mask (which could not be found anymore) and a new mask (is found), using the Details info box in MITK. I found small differences in the geometries between the old mask and the dynamic image, but not between the new mask and the dynamic image. Namely:
Spacing:
dynamic image: [1.0156, 1.0156, 5.99998]
old mask: [1.0156, 1.0156, 5.99997]
new mask: [1.0156, 1.0156, 5.99998]

It is not straighforward which name to use, since what is displayed in the Image Navigator depends on if the dynamic image has been globally or locally initiated. Therefore, for now we keep the name "Time" in the Image Navigator. What is shown is therefore not obvious for the user and should be documented clearly in the F1 help. It needs to be checked if this is the case.
A solution could be to provide a separate slider in the ModelFit Inspector View.

Since this issue was pointed out by a user recently (and I also found it confusing before reading this task description), I would like to re-open this task for discussion.

It seems to be an issue with this specific dataset. I made new set of segmentations (Prostate label and AIF label) and stored them each as DICOM segmentation. And now I find that the segmentation nodes are found as expected. It needs to be determined if the old data set is somehow corrupted or if it is a backwards compatibility issue (the masks were initially created in 2019).

This task is closed and will be worked on as part of task https://phabricator.mitk.org/T30217.

The Fit Generator Demo is no part of the currentl releases, therefore no checklist is provided.

This task is closed as wontfix since the perfusion ModelFit user manual is not provided anymore. All the information available in the user manual is given via the F1-help/ the plugin documentation at https://docs.mitk.org/2023.12/PluginListPage.html.

This task is closed as wontfix since we decided to not support this conversion method anymore (see https://phabricator.mitk.org/T30225).

I looked into the issue in more detail and found that the current implementation of the variable flip angle T_1-mapping cannot be easily replaced with a more general T_1-mapping approach. The reason for this is that not just the T_1-map is calculated but also the signal scaling factor S_0 is determined (which is additionally required for the conversion).

The Fit Generator Demo View is not part of the MITK release and is not actively supported anymore for now.

This fitting task was applied not to many cases, therefore AVID batch processing was not required and fitting was done in MITK using the formula parser.

In the current ModelFit Inspector version, the current time point is not marked at all. When moving through the time steps in the Image Navigator all data points are displayed at the same color, the current time point is not highlighted in another color. We should discuss if we want this behaviour back and check if there is a bug due to which this functionality is not present anymore.
