Abstract: In a device, method and computer program product for generation of an exposure plan for irradiating a patient, at least one reference data set independent of the patient is provided, from which an attenuation of high-energy radiation upon passage through a reference body can be determined. A patient magnetic resonance image of the patient is adapted using the reference data set and an exposure plan is generated based on the patient magnetic resonance image and the patient-specific attenuation of high-energy radiation upon passage through the patient. The patient-specific attenuation of high-energy radiation upon passage through the patient is determined using the adaptation of the patient magnetic resonance image with the reference data set.

Abstract: Techniques for converting analog medical video data to digital objects include receiving a digital video signal. The signal is produced by converting an analog video signal from playing a legacy analog medical video medium on an appropriate analog video player. Without human intervention, a first portion of a video frame of the digital video signal is determined where characters are imaged onto the analog medical video by the legacy system. The first portion of the video frame is processed in a video optical character recognition process to generate first character data. Non-video descriptive data associated with the analog medical video data is determined based on the first character data. Digital video data based on the digital video signal is stored in association with the non-video descriptive data. These techniques allow one or more extensive analog medical video libraries to be converted quickly and at low cost in human labor.

Abstract: A system and method for fusing sensor data and synthetic data to form an integrated image are described. An image registration process is used to fuse the images. The image registration process is performed on gradients of a landmark image. The gradients are extracted from both sensor and synthetic datasets for the landmark image. Using the image gradient, a center of mass for each of the gradient's curves is calculated. By solving a minimization problem to reduce error, a desired transformation operator can be obtained to match the sensor image to the synthetic image.

Abstract: A method is disclosed for visualization of plaque deposits from 3D image data records of vessel structures, in particular of the coronary vascular system, in which at least one predeterminable section of the vessel structure with the plaque deposits is segmented in the 3D image data record in order to obtain segmented 3D image data. A synthetic 3D model image of the at least one section of the vessel structure and of the plaque deposits is produced from the segmented image data, and includes only boundary surfaces of the vessel structure and of the plaque deposits. The synthetic 3D model image is produced by three-dimensional interpolation between pixels which are associated with boundary surfaces of the vessel structure, and between pixels which are associated with boundary surfaces of the plaque deposits in order to obtain a uniform grid at pixels for the 3D model image. Finally, the synthetic 3D model image or a partial volume of it is visualized.

Abstract: A method and a device are disclosed for segmenting at least one substance in an x-ray image. In at least one embodiment of the method, two attenuation values relating to different energies of an x-radiation are acquired in relation to each pixel. The pixels are mapped into a two-dimensional feature space on the basis of the acquired attenuation values, and there is subsequently determined as assessment variable from the mapping of an image environment respectively assigned to the pixels the number of those pixels that fall in a classification region assigned to the substance. It is then possible to calculate in a simple way on the basis of the assessment variable a segmented image that contains the substance and in which misclassification can largely be avoided by taking account of the neighborhood relationship of the pixels.

Abstract: Skin characteristics are analyzed. A device acquires a digital image of an area of skin of a user. A processor quantitatively analyzes the digital image to determine a characteristic of all or part of the area of skin which is indicative of a skin condition of interest. Depending on the results of the quantitative analysis, the processor provides information to the user about the area of skin relative to the condition of interest. The information provided to the user is not necessarily sufficient for a definitive medical diagnosis and may include an indication to the user as to whether a knowledgeable person should evaluate the area of skin.
