Disclosed is a method of transforming a first medical image dataset describing an anatomical body part of a patient into a reference system of a second medical image dataset describing the anatomical body part. The method encompasses taking images of a surface of an anatomical body part during both free breathing and deep inspiration breath-hold using a surface camera as well as a tomography such as a CT of the anatomical body part during deep inspiration breath-hold. Contours are extracted from the surface camera images and the tomography representing a contour of the anatomical body part such as a surface of the patient's thorax. The contour extracted from the camera image taken during free breathing is transformed into a coordinate system used for defining positions in the tomograph (i.e. a coordinate system used by the tomograph used for generating the tomography) by fusing the contour extracted from the tomography with the contour extracted from the deep inspiration breath-hold camera image and applying the transformation representing the fusion result to the camera image taken during free breathing.

ULTRASOUND TO 3D REGISTRATION USING A-MODE SIGNALS
In many medical applications, it is crucial to match or register two different image data with each other, for example live image data with previously obtained 3D image data. The present disclosure relates to registration of a 3D image dataset with (live) ultrasound data. Rather than reconstructing an image from the ultrasound data and registering the reconstructed image with the 3D image dataset, the approach of the present disclosure matches the ultrasound A mode signals output by an ultrasound transducer with simulated ultrasound A mode signals generated from the 3D image dataset.
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.

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.

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.

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.

LOCAL DIMMING OF MIXED REALITY GLASSES IN MEDICAL ENVIRONMENT
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.

Disclosed is a computer-implemented method of training a likelihood-based computational model for determining the position of an image representation of an annotated anatomical structure in a two-dimensional x-ray image, wherein the method encompasses inputting medical DRRs together with annotation to a machine learning algorithm to train the algorithm, i.e. to generate adapted learnable parameters of the machine learning model. The annotations may be derived from metadata associated with the DRRs or may be included in atlas data which is matched with the DRRs to establish a relation between the annotations included in the atlas data and the DRRs. The thus generated machine learning algorithm may then be used to analyse clinical or synthesized DRRs so as to appropriately add annotations to those DRRs and/or identify the position of an anatomical structure in those DRRs.

DETECTION OF IMAGE STRUCTURES VIA DIMENSIONALITY-REDUCING PROJECTIONS
A system and related method for computer-implemented medical image processing. The method may comprise a step of receiving (S720) input data comprising a projection of a three-dimensional, 3D, or higher dimensional image volume generated by a medical imaging apparatus. The method may comprise processing (S740) the input data by using a trained machine learning model (M) to facilitate computing a location in the 3D volume of a structure of interest. The method may include outputting (S760) output data indicative of the said location.
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.
Disclosed is a computer-implemented method of determining control data for controlling a radiation treatment apparatus. The disclosed method encompasses, in one aspect, acquisition of a Cherenkov radiation image from a body surface of a patient and comparing it to a simulated Cherenkov radiation pattern for example with regard to its position relative to an anatomical body part which is designated to be irradiated with treatment radiation. The result of the comparison is used to control a radiation treatment apparatus, for example to switch the beam off if the comparison indicates that the position of the detected Cherenkov radiation relative to the anatomical body part is not according to plan.

PATIENT MONITORING USING GRATING-BASED PHASE-CONTRAST X-RAY IMAGING
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.

COMPUTING A HYBRID SURFACE FROM MEDICAL IMAGE DATA USING TRUSTED REGIONS AND A PLAUSIBILITY CHECK
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.

COMPUTER-IMPLEMENTED METHOD FOR MODELLING A PROJECTION OF A SCENE IN THREE-DIMENSIONAL SPACE INTO A COMPOSITE IMAGE
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.

Sections of the acceleration signals which contain identified artefacts are then disregarded in subsequent processing steps, or artefacts are removed therefrom, such that a comparison between artefact-free acceleration signals acquired from different subjects having a similar and/or dissimilar physiological status is possible.
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.
