Embodiment Construction

[0051] figure 1 A flowchart of a typical implementation of the method 100 for controlling viewing parameters is shown. After the input at the input step 101, the method 100 proceeds to a determination step 110 for determining the VOI. After the VOI is determined, the method 100 proceeds to an identification step 120 for identifying the FOV. Method 100 then proceeds to control step 130 for controlling the value of the observation parameter. After the control step 130, the method 100 proceeds to a computing step 140 for computing the image. The method 100 then proceeds to a checking step 150 for checking whether there is an exit command. If there is no exit command, method 100 proceeds to identify step 120 or to determine step 110 . If there is an exit command, method 100 proceeds to exit step 199 for exiting method 100 .

[0052] Figure 2 schematically shows the field of view. When the user 210 views the image displayed on the display 200, only a part 220 of the displayed...

Abstract

The invention relates to a method (100) of controlling a viewing parameter for viewing an image on a display for displaying the image, the method comprising a determining step (110) for determining a view of interest within the image, an identifying step (120) for identifying a field of view within the display, a controlling step (130) for controlling the viewing parameter based on the field of view, and a computing step (140) for computing the image based on the controlled viewing parameter and on the field of view, which field of view comprises the view of interest, wherein the field of view is identified using an eye-tracking system for tracking an eye of a user. The method (100) provides a way of controlling the viewing parameter which reduces interruptions in viewing the view of interest. This is particularly useful for a surgeon performing a procedure on a patient using a surgical tool navigation system, when the surgeon needs to adjust a viewing parameter while watching the surgical tool and a surrounding anatomic structure displayed by the navigation system.

Description

technical field [0001] The invention relates to a method of controlling viewing parameters used in viewing an image on a display for displaying the image. [0002] The invention also relates to a system for controlling observation parameters used in observing an image on a display for displaying the image. [0003] The invention also relates to an image acquisition device comprising said system. [0004] The invention also relates to a workstation comprising said system. [0005] The invention also relates to a computer program product comprising instructions for performing the method when said program product is run on a computer. Background technique [0006] Implementations of methods of the type described in the opening paragraph are known from many image viewing and editing applications, for example from Jasc Paint Shop Pro 7. In order to control observation parameters such as brightness, the user can open the brightness / contrast control window through menu operation...
