    摘要: The invention relates to a method, an apparatus and a computer program for transferring scan geometry between a first region and a second region, similar to the first region. In the method according to the invention the first region and the second region are being identified (4), preferably in the overview image, followed by determination (6) of the first scan geometry corresponding to the first region. Then, the first scan geometry is being transferred into the second scan geometry corresponding to the second region, whereby information on geometrical correspondence between the first region and the second region is used. Preferably, the step of transferring comprises establishing corresponding mappings between similar regions and their respective scan geometries.

    摘要: A tomographic apparatus (10) includes at least two x-ray sources (14) that rotate about and alternately emit radiation into an imaging region (22). The at least two x-ray sources (14) emit radiation from a first set of angular positions during a first data acquisition cycle and from a different set of angular positions during a subsequent data acquisition cycle. At least two sets of detectors (24) detect primary radiation emitted by a corresponding one of the at least two x-ray sources (14) and produce data representative of the detected radiation. An interleaver (32) interleaves the data associated with the first and the subsequent data acquisition cycles for each of the at least two x-ray sources (14).

    摘要: In a magnetic resonance data acquisition method, magnetic resonance is excited (72, 74) in an observed nuclear species. Magnetic resonance data of the observed nuclear species are acquired (76). A plurality of different broadband decoupling radio frequency pulses (80) configured to decouple a coupled nuclear species from the observed nuclear species are applied. Each broadband decoupling radio frequency pulse has a different or randomized or pseudorandomized amplitude (110) as a function of time. Each broadband decoupling radio frequency pulse has about the same peak power, pulse duration, and frequency spread. The differences between the broadband decoupling radio frequency pulses are effective to substantially suppress cycling sidebands.
