The aim of this exercise is to load in GIMIAS a predefined workflow and perform all the steps from loading the DICOM image (acquired using XA modality) of an intracranial aneurysm with the surrounding vessels to the comparison of the aneurysm shape with another aneurysm. The exercise shows how to crop the image to isolate the region of interest (containing the aneurysm), extract the aneurysm geometry, perform different mesh editing operations to edit and refine the aneurysm geometry, and activate different visualization options, e.g. volume rendering of the vessels, visual representations of the geometry, multiple windows for shape comparison, etc.
The aim of this exercise is to explore the different types of measurements we can do using GIMIAS, on a 3D + t image. The exercise will allow to perform all the steps from loading the DICOM image (acquired using MRI modality) measure distances, select points and save their coordinates in order to analyze their displacement in time, manually draw regions of interest (ROIs), compute mean, standard deviation, minimum and maximum intensity values of the image in the ROI, and plot these values over time.
GIMIAS Tutorial 3: multimodal image fusion and comparison.
The aim of this exercise is to show different visualization and fusion functionalities applied to neurological images. The predefined workflow that will be loaded in GIMIAS will allow to load images acquired using different modalities (MRI, SPECT, PET, fMRI) and visualize them as overlaid images, compare them using more multirender windows in the same working area, display the desired number of slice and orientation, flip and rotate the images using the multislice view.
