Devices, methods, and computer programs are presented for displaying information output of a host. The method includes acquiring sequential volumetric representations of an area of the heart and defining a target tissue region andor a radiation sensitive structure region in 3D for a first of the representations. A damage sensor has a film of an alloy of nickel and titanium. The method further includes storing a first frame of the digital video stream. The present invention further discloses a liquid crystal display device comprising the backlight module. The non-myocytical marker preferably is galectin-3 or thrombospondin-2.
