Abstract: A method for planning ablation treatment using ultrasound data begins by identify pathology to be treated and one or more blood vessels proximate the treatment site in a medical diagnostic image. Ultrasonic Doppler velocity data is acquired from the flow within the vessels and the Doppler data is used to calculate the volume blood flow through the vessels. The thermal effect of the heat transported by this blood flow is considered in the planning of the ablation treatment.

Abstract: The present invention relates to a method of manufacturing a capacitive micro-machined transducer (100), in particular a CMUT, the method comprising depositing a first electrode layer (10) on a substrate (1), depositing a first dielectric film (20) on the first electrode layer (10), depositing a sacrificial layer (30) on the first dielectric film (20), the sacrificial layer (30) being removable for forming a cavity (35) of the transducer, depositing a second dielectric film (40) on the sacrificial layer (30), depositing a second electrode layer (50) on the second dielectric film (40), and patterning at least one of the deposited layers and films (10, 20, 30, 40, 50), wherein the depositing steps are performed by Atomic Layer Deposition. The present invention further relates to a capacitive micro-machined transducer (100), in particular a CMUT, manufactured by such method.

Abstract: A system (100) includes a retrieval unit (110) for retrieving an image from the storage of images, on the basis of the similarity of images from the storage of images to a query image. The similarity is defined by means of a similarity function. A relevance unit (120) computes the relevance of a first portion of the retrieved image to a respective first portion of the query image and of a second portion of the retrieved image to the respective second portion of the query image. A visualization unit (130) visualizes the relevance of the first and second portion of the retrieved image to the respective first and second portion of the query image. The relevance of the first and second portion of the retrieved image to the respective first and second portion of the query image is computed using a first and second relevance function. The computed values of the relevance are visualized, e.g. using a color coding and coloring the first and second portion of each retrieved image.

Abstract: An attribute-based digital signature system is disclosed. A first signature generating unit (1) is used for generating a first signature (10) for a document (11), based on a first signature key (12) and the document (11). A re-signing unit (2) is used for generating a second signature (13) for the document (11), based on the first signature (10) and a re-signing key (14), wherein the re-signing unit (2) is arranged for handling attributes (15, 16) associated with the first signature (10) and/or the second signature (13). The second signature (13) is associated with a second set of attributes (16,16?) determined by the re-signing key (14), wherein the second set of attributes (16) comprises a plurality of attributes.

Abstract: Methods and systems for selecting a cohort group or a patient at risk from a population of patients with mild cognitive impairment. The methods include using a computer configured to perform the steps: receiving normalized learning data from a portion of the population of patients; tuning a set of decision trees on the normalized learning data; receiving patient data from one or more patients of the population, wherein the patient data is independent from the learning data; classifying the patient data with the tuned set of decision trees to obtain patient threshold values; and displaying the patient threshold values.

Abstract: In a method and apparatus to enable increased RF duty cycle in high field MR scans, a specific energy absorption rate (SAR) calculation processor calculates the local and global SAR or even a spatial SAR map. By incorporating additional information as, e.g. patient position, the SAR calculation accuracy can be increased as well as by using more patient specific pre-calculated information (e.g. based on different bio meshes), the so called Q-matrices. A sequence controller maybe provided to create a global SAR optimal RF pulse. After the optimal RF pulse is applied, the SAR and its spatial distribution are determined. SAR hotspots are also determined. Q-matrices within an appropriate radius around the hotspots are averaged and added to a global Q-matrix in a weighted fashion. After the global Q-matrix is updated, a new optimal RF pulse is created.

Abstract: The invention provides a lighting unit comprising a substantially continuous, pliable surface (10) and a plurality of light sources. The light sources (20) are arranged to generate light beams (24) with respective optical axes (O). Each of the light sources (20) is connected to the pliable surface (10) at respective surface areas (30) of the pliable surface (10), whereby orientations of the respective surface areas (20) and orientations of the respective optical axes (O) are linked. The pliable surface (10) has a profile (Z) that is pliable into different profiles with corresponding different orientations of at least part of the plurality of surface areas (30). The lighting unit can thus easily provide different illumination profiles. In this way, a flexible lighting unit is provided, as the profile of the pliable surface can be defined and, after having been initially defined, also changed in dependence on e.g. user needs.
