Image viewing application and method for orientationally sensitive display devices

摘要

A system and method for presenting three-dimensional image volume data utilizing an orientationally-sensitive display device whereby the image volume is navigable simply by tilting, raising and lowering the display device. Doing so presents an image on the screen that relates to the angle and position of the display device such that the user gets the impression that the device itself is useable as a window into the image volume, especially when the device is placed on or near the source of the image data, such as a patient.

1. A method of displaying images on a screen of a display device, which is orientationally sensitive, the method comprising:
providing three-dimensional image volume data relating to an object to the display device; displaying on the screen of the display device a slice image of the object generated from the three-dimensional image volume data based on a location and an orientation in a coordinate system for the three-dimensional image volume data, wherein the location and the orientation in the coordinate system correspond to a location and an orientation of the display device in a real space, respectively, wherein the slice image is a geometrically reconstructed two dimensional image from the 3D volume by slicing the 3D volume according to the orientation at the location; displaying a target sign over the slice image; detecting a sliding input on the screen of the display device; generating new slice images based on changes in the location and orientation of the display device with respect to the coordinate system for the three-dimensional image volume data and based on the sliding input; and displaying an indication of a plane of the displayed slice image with respect to the coordinate system for the three-dimensional image volume data, wherein, when the new slice images are generated based on the sliding input, the new slice images are generated based on a location of the target sign over the slice image and a direction of the sliding input.
