Time-intensity Curves (TIC) for Dynamic Studies

Description of the new feature/enhancement

Some MR sequences dynamically study the enhancement of a certain tissue (e.g. pituitary MRI and breast MRI).

While it is relatively easy when we're talking about a couple of phases (arterial and venous), it becomes harder when we are trying to image the same area every 10 seconds while monitoring the enhancement pattern to get a clear idea of a suspected lesion.

This is where plotting Time-intensity Curves (TIC) comes handy, as it removes the subjective bias of examining every section by plotting an objective curve of how the signal intensity changed over time, and it allows us to compare the suspected area with other "normal" areas.

Proposed technical implementation details (optional)

Well in a dynamic study, let's take a dynamic pituitary study, generally we have multiple coronal slices (around 36), that are divided into groups of 6 (meaning we are taking 6 coronal slices from the pituitary slice every 10 seconds for the following 60 seconds).

We should be able to select an ellipse ROI over an area by drawing, and have an option in addition to it displaying the signal intensity (SI) to plot a Time-intensity Curve (TIC) over the series of slices.

Describe alternatives you've considered (optional)

I found this feature from RadiAnt to be as close as what's being used by proprietary DICOM diagnostic software:

Currently, some major features with a high priority must be implemented and the resources on this project are very limited. In order to develop more specialized tools, we need contributors.
