Abstract: The present invention relates to peripheral perfusion measurement. In order to provide more detailed peripheral perfusion characteristics for better knowledge about a current situation, a device (10) for peripheral perfusion measurement is provided that comprises an image data input (12), a data processor (14) and an output interface (16). The image data input receives at least one perfusion angiographic 2D X-ray image of a region of interest of a subject's foot and a 3D foot-model comprising spatial perfusion-related parameters. The data processor registers the 3D foot-model with the foot in the at least one perfusion angiographic X-ray image. The registering comprises a pose-estimation of the foot in the 2D X-ray image. The information is mapped between the 2D image and the 3D foot-model based on the pose-estimation. Image processing modification instructions are identified based on the mapped information. Further, the at least one image signal is modified based on the image processing modification instructions. The output interface provides the at least one modified image signal. In a first example, a regional perfusion analysis is provided. In a second example, a normalization of the perfusion signal by the fraction of perfused tissue is provided. In third example, reporting in a 3D model is provided.

Abstract: Presented are concepts for displaying medical images. One such concept generates transformation data by mapping image data of a medical image to a location in an anatomical atlas and by determining a transfer function for transforming image data of the medical image for display. The transfer function is then associated with the location in the anatomical atlas. A medical image can then be displayed by identifying a transfer function associated with a selected location in the anatomical atlas. The identified transfer function is applied to image data of a medical image that is mapped to the selected location in the anatomical atlas so as to obtain transformed image data. A transformed version of the medical image is then displayed based on the transformed image data.

Abstract: System and related method to visualize image data. The system comprises an input port (IN) for receiving i) image data comprising a range of intensity values converted from signals acquired by an imaging apparatus in respect of an imaged object, and ii) a definition of a first transfer function configured to map a data interval within said range of said intensity values to an image interval of image values. A transition region identifier (TRI) identifies from among intensity values outside said data interval, one or more transition intensity values representative of a transition in composition and/or configuration of said object or of a transition in respect of a physical property in relation to said object. A transfer function generator (TFG) generates for said intensity values outside said data interval a second transfer function. The second transfer function is non-linear and has a respective gradient that is locally maximal around said transition intensity values. A renderer (RD) then renders, on a display unit (MT), a visualization of at least a part of said image data based on the two transfer functions.

Abstract: When delineating anatomical structures in a medical image of a patient for radiotherapy planning, a processor (18) detects landmarks (24) in a low-resolution image (e.g., MRI or low-dose CT) and maps the detected landmarks to reference landmarks (28) in a reference contour of the anatomical structure. The mapped landmarks facilitate adjusting the reference contour to fit the anatomical structure. The adjusted reference contour data is transformed and applied to a second image using a thin-plate spline, and the adjusted high-resolution image is used for radiotherapy planning.

Abstract: The present invention relates to a method for use in the concurrent display of medical images from different imaging modalities. A system and a computer program product for use in relation to the method are also disclosed. In the method, a primary image and a secondary image from a different imaging modality are fused. In the fused image, a first pixel group from the primary image having primary image data values within a first range are mapped to grayscale image values. A second pixel group from the primary image having primary image data values within at least a second range are identified, and the secondary image data values of corresponding pixels in the secondary image are mapped to color image values in the fused image.

Abstract: A method of generating a modified X-ray image includes obtaining an X-ray image, obtaining a CT image corresponding to the X-ray image, determining a mapping between the X-ray image and the CT image, identifying a structure of interest in the CT image, generating an attenuation map from the CT image, the attenuation map indicative of attenuation due to the structure of interest or everything but the structure of interest on the X-ray image, and generating the modified X-ray image by subtracting the attenuation map from the X-ray image.

Abstract: An apparatus (10) for generating a training set of anonymized images (40) for training an artificial intelligence (AI) component (42) from images (11) of a plurality of persons. The apparatus includes at least one electronic processor (20) programmed to: spatially map the images of the plurality of persons to a reference image (30) to generate images (32) in a common reference frame; partition the images in the common reference frame into P spatial regions (34) to generate P sets of image patches (36) corresponding to the P spatial regions; assemble a set of training images (3) in the common reference frame by, for each training image in the common reference frame, selecting an image patch from each of the P sets of image patches and assembling the selected image patches into the training image in the common reference frame; and process the training images in the common reference frame to generate the training set of anonymized images including applying statistical inverse spatial mappings to the training images in the common reference frame, wherein the statistical inverse spatial mappings are derived from spatial mappings (33) of the images of the plurality of persons to the reference image.
