The plasma is initially trapped in a symmetrical cusp magnetic field configuration with a low magnetic field barrier to radial motion. The integrity protection method for the mobile terminal includes sensing a power-on of the mobile terminal, verifying, by a trusted entity in the normal world, the integrity of a first subsequent entity, and sending, when an integrity breach is detected in the first subsequent entity, by the trusted entity, a modification indication signal to the secure world. Compression plates are integrated into the breast coil which compress the breast either laterally or in the headfeet direction as required for optimal access to the breast. A backlight unit includes: a light guide plate configured to allow a light source to proceed to a liquid crystal panel; a light emitting diode mounted in a main body mounted on a substrate and generating a light source; and an LED package having a lead frame exposed to allow the main body to be selectively top-mounted or side-mounted, and being mounted on the light guide plate.
