Methods and apparatus for scanning an object and displaying an image in a computed tomography system
First Claim
1. A method for scanning an object in a computed tomography system, the computed tomography system including an x-ray source for projecting x-rays, a detector for detecting x-rays from the x-ray source and attenuated by the object, a display, and a processor coupled to the detector and coupled to the display for generating images on the display, said method comprising the steps of:
- obtaining scan projection data;
processing the projection data to generate image data; and
displaying at least one image slice and one three-dimensional image simultaneously on the display.

Abstract
Methods and apparatus for scanning an object in a computed tomography system during an interventional procedure are described. The computed tomography system includes an x-ray source, a detector, and a display. The detector detects x-rays projected from the x-ray source and attenuated by an object. A processor is coupled to the detector and coupled to the display for generating images of the object on the display. A helical scan is executed to generate an image slice of the object corresponding to each gantry rotation. At least one image slice and one three-dimensional image are simultaneously displayed on the display.
