An imaging system includes an imaging unit, a display unit, and at least one processor. The at least one processor is configured to acquire a first type of diagnostic imaging information of the patient; reconstruct a first image using the first type of diagnostic imaging information; if a first stop criterion for terminating imaging is not satisfied, acquire a second type of diagnostic imaging information having an increased level of acquisitional burden; reconstruct a second image; if a second stop criterion for terminating imaging is not satisfied, acquire a third type of diagnostic imaging information having an increased level of acquisitional burden, wherein the patient is maintained on a table of the imaging unit during the acquisition of the second type of diagnostic imaging information, reconstruction of the second image, and acquisition of the third type of diagnostic imaging information; reconstruct a third image; and display the third image.

Systems and methods for progressive imaging

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. Also, if a scan is prescribed either via the GUI or graphic Rx display, the affect on ISO center and DFOV is determined. This information is automatically updated on the graphic Rx display by modifying the cut-line position up/down to show ISO affect and by modifying the cut-line length to show DFOV.

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.
