摘要： A hidden structure of a volumetric data set is rendered in a medical image based on a volumetric data set received from a medical scanner. Reference information indicative of a parameter for a clip plane is received for rendering the hidden structure within the medical image. A differentiable rendering, DR, algorithm is applied on the received volumetric data set, which comprises determining a light accumulation along a viewing ray. The clip plane is approximated by including a smooth approximation to a Dirac delta distribution, which depends on the parameter comprised in the received reference information, in the determining of the light accumulation along the viewing ray. The parameter for the clip plane is optimized by optimizing an objective function. The medical image with the hidden structure visible is output for final rendering, and/or for display.

摘要： Systems and methods for automatically determining an image quality assessment of a rendered medical image are provided. A rendered medical image is received. One or more measures of interest are extracted from the rendered medical image. An image quality assessment of the rendered medical image is determined using a machine learning based image quality assessment network based on the one or more measures of interest. The image quality assessment of the rendered medical image is output.

摘要： Distance estimation is optimized in virtual or augmented reality. A distance map of a surgical instrument to a region of interest is determined, at least at the beginning and when a position of the surgical instrument has changed. A render-image is rendered based on a medical 3D image and the position of the surgical instrument, at least at the beginning and when the position of the surgical instrument has changed. At least the region of interest and those parts of the surgical instrument positioned in the volume of the render-image are shown in the render-image. Based on the distance map, at least for a predefined area of the region of interest, visible, acoustic, and/or haptic distance-information is added.
