Tomographic perfusion imaging is a well accepted method for stroke diagnosis that is available with current CT and MRI scanners. A challenging new method, which is currently not available, is perfusion imaging with an interventional C-arm CT that can acquire 4-D images using a C-arm angiography system. This method may help to optimize the workflow during catheter-guided stroke treatment. The main...
An approach is presented for analysing cardiac deformation mechanics. A physics-based deformable model is trained from a set of 4D images. The mechanics of myocardium are quantitatively analysed and the working conditions of the heart are statistically evaluated by observing their deviations from normal values.
