Patent number: 10663545Abstract: In order to execute a low-artifact magnetic resonance fingerprinting (MRF) scan, a preferred order of N k-space trajectories of a sampling pattern is determined in a computer, along which in each case an undersampled scan data set is to be scanned, such that artifacts are avoided in parameter maps created from the scan data sets in an MRF scan. The order in which the N k-space trajectories are to be sampled one after the other is varied, so at least two different orders are produced. According to the orders that result due to this variation, determined test signal characteristics are compared with each other and/or with ideal signal characteristics with respect to their artifact behavior. A preferred order is determined from the resulting orders by taking into account the results of the comparison.Type: GrantFiled: September 8, 2017Date of Patent: May 26, 2020Assignee: Siemens Healthcare GmbHInventors: Thomas Kluge, Mathias Nittka, Gregor Koerzdoerfer

Publication number: 20200158804Abstract: A method for generating control commands for execution on a magnetic resonance (MR) scanner includes receiving an MR sequence via an input interface, partitioning the MR sequence into a sequence of time slices, and defining an extendable set of sequence block control data types. Each time slice is mapped to at least one instance of a sequence block control data type or to at least one instance of a fundamental control data type for providing a stream of events. An event handler is provided for each event. A dispatcher is accessed for reading each event in the provided stream of events and passing each event together with the dispatcher to an appropriate event handler, so that the dispatcher may be called recursively by the event handlers. Fundamental control data types are translated into concrete control commands of the particular scanner to be used for execution on the MR scanner.Type: ApplicationFiled: November 14, 2019Publication date: May 21, 2020Inventor: Thomas Kluge
