    摘要： One embodiment of the present invention is a method for analyzing tubular structures in a patient, including steps of: selecting a region of interest and a location within the region of interest from a displayed tube-shaped tree representative of a tubular structure in a patient; identifying a centerline of a structure within the tube-shaped tree within the region of interest; and displaying one or more views of the region of interest. The view or views are selected from at least a segmented 3-D view having the region of interest identified, a curved view of the selected branch, a reformatted view dependent upon the identified centerline, and a 3-D view dependent upon the identified centerline.

    摘要： 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.
