US 2013/0155066 A1 · Method and system for visualizing a volume dataset

Abstract

A machine-implemented display method that, with respect to a volume dataset being rendered, enables a user to navigate to any position in space and look in any direction. Preferably, the volume dataset is derived from a computer tomography (CT) or magnetic resonance imaging (MRI) scan. With the described approach, the user can see details within the dataset that are not available using conventional visualization approaches. The freedom-of-motion capability allows the user to go to places (positions) within the volume rendering that are not otherwise possible using conventional “orbit” and “zoom” display techniques. Thus, for example, using the described approach, the display image enables a user to travel inside physical structures (e.g., a patient's heart, brain, arteries, and the like).

Dependent claims

An article comprising a non-transitory machine-readable medium that stores a program, the program being executable by a machine having a hardware component and a display routine, comprising:

program code to calculate, for a given frame of a display image, a difference between a current frame rate and a desired frame rate and, based on the difference, to render a next frame of the display image by adjusting one of:
a pixel column, and a pixel row;
and
program code operative at an end of the given frame to rescale the display image back to a given screen resolution to account for a change in a number of pixels that results from adjustment of the pixel column or pixel row.
