New real-time MRI imaging techniques enable the acquisition of serial images with a temporal resolution of up to 20 ms. These new imaging sequences provide cardiac parameters such as cardiac function and blood flow over multiple heart cycles and their variation over time. To quantify these parameters new analysis methods are required. Our proposed solution combines automatic image processing with interactive exploration techniques in a web application setup. The solution has been successfully tested with data from arrhythmic patients as well as volunteers performing Valsalva maneuver and physical exercise tests.
