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. The sequence controller dynamically links the selected image contrast waveform segments and one imaging waveform segment, causing the MR imaging device to acquire a new image with the selected waveform segment mechanisms.
