摘要： A training module is used to produce a database that stores histogram landmarks for MR images acquired with different scan parameters such as TR, TE flip angle and inversion recovery time. This database is used by a transformation module which enables an MR image acquired at one prescribed set of scan parameters to be transformed into MR images that simulate MR images acquired with different scan parameters.

摘要： A circuit for driving GTL-type buses actively drives a bus trace towards a first reference voltage when a signal in a first voltage state is detected at its input and actively drives the bus trace towards a second reference voltage for a selected period when the signal at its input transitions from the first voltage state to a second voltage state. The circuit includes a flip-flop for storing the sequential voltage states of the signal, logic for comparing the current voltage state of the signal with a replica of the preceding voltage state of the signal, and first and second transistors of complementary conductivity types, for driving the bus trace to first or second reference voltages, respectively, when activated. The first transistor is turned on when the signal is in the first voltage state. The second transistor is turned on for a period determined by the clock signal driving the flip flop, the type of flip-flop, and, optionally, additional logic gates, when the signal transitions from the first voltage state to the second voltage state.

摘要： A system and method for rating the validity of multiple data processing algorithms A1-An on a set of multi-dimensional input data I where P1-Pn is the output data produced by the competing algorithms. Processing steps include: (1) computing the Fourier Transform or the phase congruence of the input data I, (2) computing the Fourier Transform or the phase congruence of the output data P1-Pn, (3) computing the phase of the data computed at step 1, (4) computing the phases of the data computed at step 2, and (5) computing a similarity metric, such as the normalized cross correlation of each phase computed at step 4 with the corresponding phase computed at step 3. The similarity metrics computed at step 5 can be ordered to provide a ranking of the algorithm validity.
