Publication number: 20100220911Abstract: At least one approximation image is created of the image at one or multiple scales. Translation difference images are created by pixel-wise subtracting the values of an approximation image at scale s and the values of a translated version of the approximation image. A non-linear modification is applied to the values of the translation difference image (s) and at least one enhanced center difference image at a specific scale is computed by combining the modified translation difference images at that scale or a smaller scale with weights Wi,j. An enhanced image is computed by applying a reconstruction algorithm to the enhanced center difference images. The non-linear modification of the values of the translation difference images is steered by the values of an orientation map which comprises for each pixel a local direction of interest.Type: ApplicationFiled: October 2, 2008Publication date: September 2, 2010Applicant: AGFA HEALTHCARE NVInventors: Tom Bertens, Pieter Vuylsteke

Patent number: 7786990Abstract: A cursor mode display system and method for indicating an offset distance between a cursor position on an image and a closest image slice in a corresponding image series. First, the three-dimensional coordinates associated with the cursor position on the image are determined by projecting the cursor position onto a three-dimensional patient coordinate system. The closest image slice is then identified as the image slice in the corresponding image series that is closest to the three-dimensional coordinates of the cursor position. The offset distance between the closest image slice and the three-dimensional coordinates associated with the cursor position is then calculated. If the offset distance does not exceed a threshold value, then the closest image slice is displayed. Otherwise a modified version of the closest image slice is displayed.Type: GrantFiled: November 22, 2006Date of Patent: August 31, 2010Assignee: Agfa HealthCare Inc.Inventors: Rainer Wegenkittl, Donald K.

Patent number: 7787679Abstract: A system and method for navigating an image series, the image series containing a number of substantially aligned planar images. First, the images of the image the image series are grouped into a number of subseries, the number of subseries being less than the number of substantially aligned planar images in the image series. A representative image series is generated by generating an image from each subseries. The representative image series is displayed. It is determined whether an image from the representative image series has been selected. If an image from the representative image series has been selected, then the subseries associated with the selected image is displayed.Type: GrantFiled: November 22, 2006Date of Patent: August 31, 2010Assignee: Agfa HealthCare Inc.Inventors: Rainer Wegenkittl, Donald K.
