Abstract
A system and method for creating a panoramic projection of a volumetric image of an object is disclosed. A virtual camera is placed in a center of a cubic space within the object. Images obtained from the camera are projected onto a single plane. A front image is mapped in a window at a center of the plane. A left, right, top and bottom image of the cubic space are mapped around the rectangular window such that the left, right, top and bottom images form a continuous image surrounding the rectangular window.
Claims16
A method for performing a virtual fly-through inside of an anatomical lumen, represented by medical image data, using a medical image processing system, comprising:
- placing a virtual camera within the lumen;
- obtaining five images of the interior of the lumen from the point of view of the virtual camera, at 90° viewing angles, the five images comprising a forward image, a left image, a right image, a top image and a bottom image;
- displaying a first virtual fly-through frame by mapping the forward image to a rectangular window at the center of the frame while the remaining four images are projected to windows to the left, right, top, and bottom of the rectangular window, respectively;
- and
- repeating steps of advancing the position of the virtual camera down the lumen and displaying a subsequent virtual fly-through frame in the manner in which the first virtual fly-through frame was displayed until the virtual fly-through is completed.
A system for performing a virtual fly-through inside of an anatomical lumen, represented by medical image data, comprising:
- an image acquisition apparatus for acquiring the medical image data;
- and
- an image processing system for:
- receiving the acquired medical image data;
- placing a virtual camera within the lumen;
- obtaining five images of the interior of the lumen from the point of view of the virtual camera, at 90° viewing angles, the five images comprising a forward image, a left image, a right image, a top image and a bottom image;
- displaying a first virtual fly-through frame by mapping the forward image to a rectangular window at the center of the frame while the remaining four images are projected to windows to the left, right, top, and bottom of the rectangular window, respectively;
- and
- repeating steps of advancing the position of the virtual camera down the lumen and displaying a subsequent virtual fly-through frame in the manner in which the first virtual fly-through frame was displayed until the virtual fly-through is completed.
