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.

Abstract: A data processing system is operable in a multitasking mode to include at least one process having a plurality of threads. Exception management is done on a per thread basis, as opposed to a per process basis. Further, when a process termination exception occurs, each thread is accessed to execute any process termination exception handler associated with the thread.
