Abstract
Methods for changing the values of parameters of a pulse sequence of a magnetic resonance imaging scanning procedure to change a characteristic of at least one image resulting from the scanning procedure are disclosed wherein an input device in the room with the patient is used to provide an input to the magnetic resonance imaging system. The input device is preferably a hand-operated device, such as a mouse. Values of parameters corresponding to TR time, TE time, slice axis, slice thickness, slice location, field of view, oblique angle and resolution may, for example, be changed by providing suitable inputs through the input device. Methods of conducting MRI scans are also disclosed wherein an updated pulse sequence is formed based on a current pulse sequence and an input from an input device, during execution of the current pulse sequence. MRI systems are disclosed, as well. The methods and systems are particularly suitable for use by a surgeon during a surgical procedure, to obtain magnetic resonance images in real-time or nearly in real-time.
