Abstract:
In a method and apparatus for magnetic resonance imaging preview and establishing an MR model, an MRI scanner is controlled so as to execute an MR model scan sequence to perform an MRI scan of a designated patient, to obtain an MR model of the patient. One type of scan sequence is sequentially selected from all types of scan sequence supported by the MRI device, and one parameter set is sequentially selected from at least one parameter set supported by this type of scan sequence. The selected sequence and the selected parameter set are used to subject the MR model to a virtual MRI scan, to obtain an MR preview image corresponding to the selected sequence and the selected parameter set for the sequence C. This is repeated for all types of scan sequence supported by the MRI scanner and all parameter sets supported by each type of scan sequence. An MR model of a patient can thereby be established, and MR images of the patient to be previewed quickly, before an MRI scan of the patient is actually begun.

Claim (Index 13):
An apparatus for establishing a magnetic resonance (MR) model, comprising:\n a magnetic resonance imaging (MRI) scan processor configured to control an MRI scanner to execute a preset MR model scan sequence so as to perform an MRI scan of a designated patient in order to obtain an MR image; and a model establishing processor configured to calculate a signal strength of each type of tissue of a human body under the MR model scan sequence, according to an MR characteristic parameter of each type of tissue of the human body and a scan characteristic parameter of the MR model scan sequence, and to individually map the calculated signal strength of each type of tissue of the human body under the MR model scan sequence to a brightness interval of the MR image, and to determine a tissue to which each pixel point on the MR image obtained by the MRI scan module belongs, according to the mapped signal strength of each type of tissue of the human body under the MR model scan sequence, and to establish an MR model of the patient on the basis of the tissue to which each pixel point on the MR image obtained by the MRI scan module belongs, and a position of the pixel point.
