20080317342 | Method for segmenting structures in image data records and image processing unit for carrying out the method - In the method according to at least one embodiment of the invention, a first segmentation of a structure in an image data record is firstly carried out, and a first final segmentation result is obtained therefrom. A region in the image data record is selected based on the first final segmentation result obtained. A first band is placed at a first, outwardly pointing distance from the selected region. This first band characterizes a background region. A second band is placed at a second, inwardly pointing distance from the projected first final segmentation result of the first segmentation. This second band characterizes a structure region. A further segmentation is carried out based on the characterized background region and the characterized structure region, and the final segmentation result of the further segmentation is saved and/or displayed. Furthermore, an image processing unit for carrying out the method is disclosed. | 12-25-2008 |
20080317351 | Method for interactively segmenting structures in image data records and image processing unit for carrying out the method - In the method according to at least one embodiment of the invention, an image data record having a structure to be segmented is first of all displayed by display equipment. Using an input apparatus, a segmentation algorithm to be used is selected from a group of different segmentation algorithms, including a contour-based segmentation algorithm, a region-based segmentation algorithm and manual segmentation, based on the local image contrast in a region to be segmented in the image data record. A region to be segmented in the image data record is marked, and the structure to be segmented in the marked region is segmented using the selected segmentation algorithm, and a segmentation result of the segmentation is displayed. This procedure (selecting a segmentation algorithm/marking a region/segmenting the region/displaying) is repeated until the structure to be segmented is completely segmented in the displayed image data record and a boundary line of the structure is produced as the final segmentation result. Lastly, the final segmentation result is saved and/or displayed. Furthermore, an image processing unit is disclosed for carrying out the method of at least one embodiment. | 12-25-2008 |
20090010506 | Method for Processing Image and Volume Data Based on Statistical Models - A method for visually displaying and/or evaluating measurement data from imaging methods involve the following acts: a) calculating a parameterized statistical model from example voxel data sets that map different objects of an identical object class; b) carrying out at least one imaging method on an object to be examined of the object class in order to extract real measurement data; c) setting a set of model parameters of the parameterized statistical model; d) determining a difference between the real measurement data and the parameterized statistical model; e) repeating steps c) and d) while changing the model parameters until the difference between the real measurement data and the parameterized statistical model is minimal; and f) visually displaying and/or evaluating the statistical model parameterized in aforementioned manner. | 01-08-2009 |
20090202121 | METHOD FOR CONTROLLING AN IMAGE DATA ACQUISITION AND/OR EVALUATION PROCEDURE IN MEDICAL EXAMINATIONS - In a method to control the acquisition and/or evaluation procedure of image data in medical examinations, in a previously acquired planning image data set entirely or partially covering a target volume, spatial information of the target volume is determined automatically using a statistical model of the target volume based on data about real anatomy. The acquisition and/or evaluation operation is controlled using the spatial information. A statistical model of at least one greyscale value distribution in the region of the surface of the target volume is used to calculate the location information. | 08-13-2009 |
20100002921 | MEDICAL IMAGE ACQUISITION APPARATUS AND OPERATING METHOD THEREFOR - In a medical image acquisition device, and a method for operating such a device, before acquiring a current planning image data set from a subject, a statistical atlas is generated that is a statistical compilation concerning at least one part of the human body, the statistical compilation including an average image data set electronically associated, in the statistical atlas, with association information that identifies anatomy of the human body represented by the statistical compilation. The statistical atlas is compiled from multiple planning image data sets acquired using a specific measurement protocol. After the current planning image data set is acquired, the stored average image data set is transformed into the current planning image data set, so that the association information associated with the average image data set are accurately also associated with the current planning image data set. A diagnostic image acquisition of the subject is then controlled using the association information that is now associated with the current planning image data set. | 01-07-2010 |
