Abstract

According to the present invention, at least one image pair, consisting of a fluoroscopic image and an angiographic image taken from the same viewing position of the imaging device relative to the patient at the time of capturing the respective image, is acquired. This is referred to as the acquisition phase. This is followed by a live phase, in which a live fluoroscopic image is registered individually with the fluoroscopic image of at least one image pair, such that the spatial relationship between the live fluoroscopic image and the fluoroscopic image, and thus with the angiographic image and the image pair in general, becomes known. Angiographic information representing the vascular structure can then be taken from the part(s) of the angiographic image(s) within the image pair(s) which overlap with the live fluoroscopic image and be overlayed over the live fluoroscopic image. The present invention focusses on the acquisition phase, in which the fluoroscopic image and/or the angiographic image of at least one of the at least one image pair is displayed after acquisition of said fluoroscopic or angiographic image, respectively. The position at which the image is displayed depends on the viewing position of the imaging device relative to the patient when capturing the respective image.

Abstract

Disclosed is a computer-implemented method of validating a determined deformation of an image rendering of an anatomical structure between digital medical images. The disclosed method encompasses a comparison of the position of corresponding image constituents representing the same moving anatomical structure throughout a set of 4D-CT slices as determined by 1) elastic fusion from a reference slice to the other slices and 2) segmentation of a contour of the anatomical structure in each of the slices, for example (only) the other slices. This procedure allows determining the validity of the fusion results. This allows improving the quality of determining the movement of the anatomical structure for planning radiation treatment of the anatomical structure.

Abstract

Disclosed is a computer-implemented method of determining imaging control data for controlling medical imaging for localizing the position of an anatomical body part. The disclosed method encompasses generation of synthesized medical images from a tomographic planning image at an image contrast which allows to appropriately recognize a representation of soft tissue in the synthesized medical images. An imaging parameter, for example the energy, of a (virtual) beam of imaging radiation is adjusted to achieve such a contrast. The determined value of the imaging parameter can then be used later for image-based tracking of the anatomical body part during a medical procedure such as radiation treatment. For example, too high energy values should be avoided because they would result in a comparably low contrast of image constituents representing soft tissue because only a small fraction of the energy would be absorbed by the soft tissue.

Abstract

The disclosed method encompasses performing local dimming of a dimmed area within a display area of mixed reality glasses. The dimmed area comprises a part of the display area on which a virtual object is displayed. While local dimming increases perceptibility of the virtual object, it might impair usability since it blocks real world objects from view. This is avoided by reducing a dimming intensity of the local dimming in at least a part of the dimmed area.

Abstract

Disclosed is an incision foil made of a sterile, thin adhesive plastic film with a defined pattern printed on it (e.g. a fine grid pattern) which can be stuck e.g. on a patient's skin surface and which marks the anatomical region of interest. Using a camera, images are acquired of the attached film and the deformation of the pattern is digitized. With a computer vision algorithm the surface of the patient, which corresponds to the surface of the film, is reconstructed from the detected pattern features in the images in comparison to the known original undeformed pattern. Disclosed is also a method for determining a geometry of the surface of the patient using the incision foil.

Abstract

Disclosed is a computer-implemented method of determining the position of an image rendering of a region of interest in medical image data which encompasses determination of the position of an anatomical region of interest (e.g. a treatment target) in contrast-enhanced medical image data. The contrast enhancement is due to using a specific imaging modality, namely grating-based phase contrast imaging (for example, dark-field contrast imaging). This allows to identify a sharper contour of soft tissue in the image than could be achieved with approaches known from the state of the art. The region of interest is identified in the grating-based phase contrast image by comparing it to a DRR generated from planning data using a known positional transformation between the image datasets. Such a procedure can be used in the framework of positioning a patient ready for radiation treatment.

Abstract

Disclosed is a computer-implemented method of determining a control parameter for controlling a medical imaging device. The disclosed method encompasses acquiring an operating parameter such as an imaging depth of an ultrasound probe used for imaging an anatomical structure (e.g. an internal organ or bony tissue or cartilage) and using the operating parameter as a guidance for appropriately orienting an x-ray device to generate an image of the same anatomical structure from for example the at least substantially same perspective as the perspective used for generating the ultrasound image. In examples, this is accomplished by using a transformation matrix which is suitable to transform the operating parameter of the ultrasound device into a corresponding control parameter of the x-ray device, or by using an appropriately configured, specifically trained, learnable algorithm such an artificial intelligence algorithm for determining the control parameter of the x-ray device.

Abstract

This disclosure encompasses approaches for determining whether an anatomical region is suitable for comparing the planning image (the CT) to the live positioning image (a surface camera image) or whether it is likely to be subject to deformation for example due to swelling and thus generally an undesirable basis for patient positioning. A first method aims at using only anatomical regions which are likely not to be subject to such behaviour as basis for establishing a positional relationship between the planning image and the live positioning image. A second method aims at determining whether differences in image contents between the planning image and the live positioning image are plausible, for example acceptable due to known effects occurring when positioning the patient.

Abstract

A computer-implemented method for modelling a projection of a scene in three-dimensional space into a composite image by a camera system comprising a plurality of cameras is presented. In particular, in this method the scene is subsequently projected onto a plurality of camera unit spheres and a compositing unit sphere. Each camera unit sphere of the plurality of camera unit spheres represents one camera of the plurality of cameras, respectively. The compositing unit sphere unifies the plurality of camera unit spheres, wherein a compositing unit sphere centre of the compositing unit sphere is equally distanced by a unified offset to each camera unit sphere centres of the plurality of camera unit spheres. A radius of the camera unit spheres and the compositing unit sphere corresponds to an alignment distance, wherein the alignment distance relates to an extrinsic distance between the camera system and a point of interest. Thus, the proposed method inter alia allows to improve the modelling of a projection of a scene in three dimensional space into a composite image by a camera system comprising a plurality of cameras in view of parallax. In particular, a parallax of zero can be achieved at the alignment distance.

Abstract

According to the present invention, the method presented herein may determine, which lesions of a patient need modulation, and which not. In an optional step an arc setup optimization is performed for creating the RT treatment plan. Moreover, a conformal shape optimization is performed, preferably for all lesions of the patient. Furthermore, a VMAT optimization is performed with the restriction that conformal the shapes determined before must stay conformal during the VMAT optimization for subset of lesions. In this way, the benefits of conformal arcs and modulated arcs are combined by generation of treatment plans using hybrid arcs. This method allows that each arc can contain both conformal and modulated apertures.

Abstract

Disclosed is a computer-implemented method which encompasses registering a tracked imaging device such as a microscope having a known viewing direction and an atlas to a patient space so that a transformation can be established between the atlas space and the reference system for defining positions in images of an anatomical structure of the patient. Labels are associated with certain constituents of the images and are input into a learning algorithm such as a machine learning algorithm, for example a convolutional neural network, together with the medical images and an anatomical vector and for example also the atlas to train the learning algorithm for automatic segmentation of patient images generated with the tracked imaging device. The trained learning algorithm then allows for efficient segmentation and/or labelling of patient images without having to register the patient images to the atlas each time, thereby saving on computational effort.

The method encompasses determination of the orientation of a medical stimulation electrode from medical image data showing an image of the electrode. A first scan is generated from which the position of the electrode is determined, and a second scan with optimized imaging parameters is generated using the same or a different imaging modality. The second scan shows a for example more precise image of the electrode and is used to determine the rotational orientation of the electrode along its longitudinal axis.

Abstract

The disclosed computer-implemented method of detecting at least one foreign object in one or more intraoperative images encompasses the provision and use of one or more intraoperative images, which are compared to expected image content. This also includes particularly the use of live intraoperative video data that are acquired and used in the computer-implemented method defined herein. The method further encompasses the creation, i.e. the calculation and or provision, of expected image content based on several different inputs. Such creation of expected image content can be based on e.g. data associated with the patient's body undergoing a medical procedure, parameters that are indicative of said medical procedure, and/or imaging parameters of the individual imaging device used to generate said one or more intraoperative images. In a further step, a comparison between the expected image content and the one or more acquired intraoperative images is conducted, preferably using an image and/or video analysis algorithm for analyzing the at least one acquired intraoperative image and for automatically detecting the at least one foreign object in the intraoperative image.

Abstract

The present invention relates to a method for determining the spatial position of objects, in particular medical objects. First position data is acquired that describes a spatial position of an object in a first coordinate system. First transformation data is acquired that transforms the object's position from the first coordinate system to a second coordinate system. Based on the foregoing data, second position data is acquired that specifies the spatial position of the object in the second coordinate system. Second transformation data is acquired that transforms the object's position from the second coordinate system to an inertial coordinate system. Based on the second position data and the second transformation data, inertial position data is determined that specifies a position of the object in the inertial coordinate system.
