Add functional MRI support to InVesalius

[paulojamorim]

InVesalius currently does not support the simultaneous visualization of functional and structural MRI. This task will expand the support to processed functional MRI.

It is suggested to add a new tab "Images" (like image below) to show or hide the different exams or processing on the image such as applying filters. In the case of fMRI, two exams will be shown in the list (structural and functional).

Hi Paulo, I would be curious about the feature for simultaneous display.

• If I understood well it would be a "selection tab" in which we would overlay in all (sagittal, coronal and axial + volume) in case of fMRI, the fMRI and structural? Would registration be already done between functional and structural or is that as well something to add?
• as well I would be curious as to know more about the filters/other exams you would want to add in the image section

Thanks in advance for the answer.

Hi @miki998 ,

Thanks for your interest.

The idea of the new "Images" tab is because InVesalius currently only works with one exam at a time. When the user loads the exams, the tab could have listed "Structural", "Functional", "Registered" and the user could choose which one to analyze.

About the registration method, @tfmoraes (another InVesalius developer) already has something ready. We can use from some library too.

InVesalius only works with one volume. The visualization of the sagittal, coronal and axial orientations is done by changing the camera position.

About the filters, we intend to insert basic filters like mean, median, sobel, etc.

hi @paulojamorim , I am really interested about adding this new functionality in invesalius3
as it is possible to expand the capabilities of InVesalius to support processed functional MRI, making it a more useful tool for medical professionals working with this type of data
I have already installed and run the program and have been studying about various aspects of InVesalius , the more i read the more it got interesting , and the more I wanted to learn about it
I have already completed step1 and step2 of application process and working on my draft proposal, that will be ready earliest possible.
I hope my understanding of this project do align with the requirements.

@miki998 we need to breakdown this issue into smaller steps. Please, do that and create separate issues as a roadmap to achieve the final goal of full fMRI support.
