Abstract
Method for producing an image of an object, for example, tissue having fat and water components. A uniform magnetic field is generated to magnetize the object. A shaped pulse sequence is selected for each of waveform, phase and frequency components of an RF signal. An RF signal which includes the selected waveform, amplitude and frequency pulse sequences is generated to produce transverse magnetization in the object. First, second, and third changing magnetic fields are then generated in the object and a series of gradient echoes are produced in response thereto. From the gradient echoes, an image of the object may be produced.
