Abstract:
An MRI system comprising:a magnet system for producing a polarizing magnetic field in a magnet bore;a scan control device including a display mounted therein, the scan control device being moveable within the magnet bore and being manipulatable to aim at a subject when said subject is located in the magnet bore;a set of tracking coils mounted to the scan control device;a pulse generator for controlling operation of the MRI system to perform an imaging pulse sequence in accordance with a set of scan parameters and for controlling operation of the MRI system to acquire NMR tracking signals from the set of tracking coils;a locator system for calculating location and orientation of the scan control device from the acquired NMR tracking signals and producing updated scan parameters for the pulse generator; andimage reconstruction means for receiving NMR imaging signals produced by the imaging pulse sequence and reconstructing an image of the subject;wherein the location of the image is determined by the updated scan parameters produced by the locator system.
