  • Patent number: 5415163
    Abstract: Method for diagnosing and treating tissue suspected of containing a lesion. A shaped pulse sequence is selected for each of waveform, phase and frequency components of an RF signal based upon characteristics of the tissue suspected of containing a lesion and an RF signal comprised of the selected waveform, amplitude and frequency shaped pulse sequences generated. A series of echoes is received in response to the generated RF signal and a real-time MR image of the tissue suspected of containing a lesion is produced using the series of received echoes. The tissue is then diagnostically evaluated for the presence of lesions using the produced real-time MR image.

  • Patent number: 5202631
    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.
