Patent number: 6704593Abstract: Realtime magnetic resonance imaging (MRI) uses cardiac and respiratory monitoring tools to avoid or minimize motion-induced image artifacts. A series of initial MR images are associated with the physiological data from the cardiac, respiratory, or other monitoring tools. The tools provide physiological data in conjunction with anatomic or spatial information such that the optimal gating times (i.e., for acquiring MR image data) in the cardiac and respiratory cycles can be identified and the optimal acquisition durations are identified relative to the physiological data. The process then uses MRI with the identified optimal gating times and acquisition durations to produce a high quality output image of the anatomy of interest. The high quality image can be one or more of the following: a two-dimensional (2D) with a higher signal-to-noise ratio (i.e.Type: GrantFiled: April 19, 2001Date of Patent: March 9, 2004Assignee: Sunnybrook & Women's College Health CentreInventors: Jeff Stainsby, Marshall S.

Patent number: 6507749Abstract: The present invention is directed to a method and system for tracking the motion of fluid traveling through a vessel and determining its velocity spectrum from magnetic resonance data collected within a single cycle. The present invention provides a process of independently acquiring and processing MR data from a single cardiac cycle. By combining a SPAMM excitation with a two-dimensional selective excitation, suitable tags of fluid flowing through the vessel may be created. The combination of the excitations produces a sinusoidal variation of transverse magnetization along a column of the fluid. A succession of gradient echoes are then collected to provide information about the flow of fluid in the excited vessel. Each gradient echo undergoes a transformation to obtain a 1-D projection of the excited fluid across the vessel. The magnitudes of the projections are then used to construct a velocity spectrum of the fluid.Type: GrantFiled: July 18, 2001Date of Patent: January 14, 2003Assignee: Sunnybrook and Women's CollegeInventors: Christopher K. Macgowan, Michael L. Wood
