Embodiment Construction
[0013] refer to figure 1 , shows a patient 10 being treated for cardiovascular disease. A patient 10 is placed in the imaging field of a magnetic resonance scanner 20 . The scanner is included for generating B in the imaging area 0 The main magnetic field magnet 22 of the field. gradient coil 24 across the B 0 field, usually gradient magnetic fields are induced along three orthogonal axes. The whole body RF coil 26 transmits RF pulses to excite and manipulate resonance within the patient in the imaging region. The whole body RF coil optionally also receives RF resonance signals from the examination region. A surface or other local RF coil 28, if present, receives the resonant signal. Optionally, the local coil is also capable of inducing and manipulating resonance. A sequence controller 30 controls the RF and gradient coils to achieve a selected magnetic resonance imaging sequence. Sequence memory 32 stores DWI, PWI, MRA and other imaging sequences. A reconstruction p...
