  • Publication number: 20130131493
    Abstract: A method for performing an examination of a patient using a dual-modality imaging system includes accessing a list that includes a magnetic resonance imaging (MRI) examination protocol to be used to perform a predetermined MRI examination, the examination protocol including a plurality of MRI protocol actions, receiving an input selecting at least one of the MRI protocol actions, scanning the patient using the MRI examination protocol, scanning the patient using a positron emission tomography (PET) imaging system to acquire PET data, and marking the PET data, using a first visual indication, to indicate the selected MRI protocol action. An imaging system and a non-transitory computer readable medium are also described herein.

  • Patent number: 6061420
    Abstract: Methods and apparatus for a multislice graphic Rx display which, in one embodiment, determines a true image location in the Z axis, selects a the correct scan data for image generation, and if a scan is initiated via the GUI or via graphic Rx, determines the affect on the ISO center and DFOV, are described. More particularly, the system determines the offset from the scan plane for each image plane, so that the true image location in Z is displayed. The image offset from the scan plane is a function of the detector row thickness, the number of detector rows, the scan pitch (helical scanning only), the image thickness, and the gantry tilt angle. Further, the image thickness is selected by the user via the GUI, and constrains the image interval which is displayed on the graphic Rx display. Based on image thickness and image interval, the correct scan data is selected so that images are generated at locations exactly matching those shown on the graphic Rx display.
