  • System and method for interactive image contrast control in a magnetic resonance imaging system
    Patent number: 6377046
    Abstract: A magnetic resonance (MR) imaging system equipped with real-time imaging capability and method of interactively prescribing image contrast are disclosed herein. The MR imaging system includes a sequence controller for constructing MR imaging pulse sequences and a waveform memory for storing waveform segments. The MR imaging system allows an operator to interactively prescribe image contrast mechanism prior to and/or during real-time imaging. The use of image contrast waveform segments, only as needed, minimizes unnecessary MR scan time.
    Type: Grant

  • MR imaging system with interactive image contrast control over a network
    Patent number: 6362620
    Abstract: An interactive magnetic resonance (MR) imaging system includes a MR imaging device, a network coupling the MR imaging device and a remote facility, an operator interface coupled to the MR imaging device and the network, a memory coupled to the MR imaging device, and a sequence controller coupled to the memory. The MR imaging device is configured to acquire and reconstruct MR data in real-time of a current imaging section and display a MR image in real-time of the current imaging section. The network provides remote services to the MR imaging device. The operator interface permits an operator to select from a plurality of image contrast mechanisms. The memory stores a plurality of image contrast waveform segments and at least one imaging waveform segment. Each of the plurality of image contrast waveform segments and the at least one imaging waveform segment is distinctly addressable such that each waveform segment can be independently accessed from the memory.
