Abstract:
1. An image display method which displays an image of an object of examination showing a periodic contracting movement by image processing performed by a computer, the image display method comprising: defining a plurality of view angles, wherein each of the view angles with respect to the object of examination is less than 90 degrees, and defining at least three kinds of phases in the contracting movement of the object of examination, each view angle comprising a combination of a first angle expressed in terms of a head direction and a tail direction and a second angle including a first oblique direction and a second oblique direction with respect to the object of the examination; preparing a plurality of first three-dimensional image data including temporal elements according to the view angles from four-dimensional data including the temporal elements of the object of examination, or a plurality of second three-dimensional image data including the temporal elements in which each of the view angles for the object of examination has been moved at one of the first angle and the second angle combinations with respect to the object of examination for each of the phases, from the four-dimensional image data, with each phase fixed; movie displaying, on a monitor screen, the plurality of first three-dimensional image data of the object of examination showing the contracting movement as respective moving images at the same time under the condition of fixing each of the view angles, the moving images being arranged in vertical and horizontal directions of the monitor screen, or movie displaying, on the monitor screen, the plurality of second three-dimensional image data as respective moving images at the same time under the condition of fixing the phase, after the plurality of second three-dimensional image data has been moved at one of the first angle and the second angle combinations; and determining, after one of the plurality of first three-dimensional image data displayed as the respective moving images at the same time on the monitor screen is selected or one of the plurality of second three-dimensional image data displayed as the respective moving images at the same time on the monitor is selected, a first view angle or a second view angle, which is associated with the selected one of the plurality of first three-dimensional image data or the selected one of the plurality of second three-dimensional image data, as an optimal view angle.
