Abstract: A parameter transformer generates level parameters, indicating an energy relation between a first and a second audio channel of a multi-channel audio signal associated to a multi-channel loudspeaker configuration. The level parameter are generated based on object parameters for a plurality of audio objects associated to a down-mix channel, which is generated using object audio signals associated to the audio objects. The object parameters have an energy parameter indicating an energy of the object audio signal. To derive the coherence and the level parameters, a parameter generator is used, which combines the energy parameter and object rendering parameters, which depend on a desired rendering configuration.

Abstract: An apparatus (1) for rotating objects (40) on screens (9) defines a hand axis (20) in response to 3D position information related to the hands (21, 22) of a user and detects a changed orientation of the hand axis (20) with respect to a 3D space and calculates a rotation for the object (40) on the screen (9) in response to said detecting. This way, to rotate the object (40) on the screen (9), an imaginary copy of the object (40) is considered to be inside an imaginary ball (41) held by the user, which imaginary ball (41) is being rotated. The changed orientation of the hand axis (20) comprises changes in angles between the hand axis (20) and the axes (31, 32, 33) of the 3D space. To improve stability in case of each one of said changes being unequal to zero, the apparatus (1) further detects the angles and compares the respective angles with respective thresholds and reduces or weights the respective changes in response to respective comparison results.

A joint probability distribution (520) is determined for at least two planned ablations in the target volume. A final configuration is visualized (530) to determine if plan objectives are met based on a probability of treatment for the target volume.

Abstract: The invention relates to a sensor device (100) and a method for the detection of magnetic particles (1) in a sample chamber (2) with a contact surface (11). The sensor device (100) comprises a sensor unit (120, 130) for detecting magnetic particles (1) in a target region (TR) and/or in at least one reference region on the contact surface. Moreover, it comprises a magnetic field generator (140) for generating a magnetic field that shall guide magnetic particles to the contact surface. With the help of these components, an “auxiliary parameter” is determined that is related to the magnetic particles (1) and/or their movement but that is independent of binding processes taking place in the target region between magnetic particles and the contact surface. The auxiliary parameter may for example be related to the degree of mismatch between the positions reached by the magnetic particles (1) under the influence of a magnetic field and the target region (TR).

Abstract: A method, system and program product are provided for planning an intervention procedure in a body lumen. A CT scan of the body lumen is performed. A virtual rendering is created of the inside of the body lumen corresponding to an interventional camera image. Then a virtual tape corresponding to a planned path for the intervention procedure is projected onto a wall of the body lumen. The virtual tape is projected onto the lumen wall, which is relatively distant from the camera point on the virtual rendering, so the tape does not appear to oscillate like a central thread. Also, since the virtual tape is located on the lumen wall, it does not occlude the center of the lumen, allowing a user to better visualize the lumen during planning, during fly through, and even during an actual intervention.

Abstract: A matrix array ultrasound probe passively dissipates heat developed by the matrix array transducer and beamformer ASIC away from the distal end of the probe. The heat developed in the transducer stack is coupled to a metallic frame inside the handle of probe. A metallic heatspreader is thermally coupled to the probe frame to convey heat away from the frame. The heatspreader surrounds the inside of the probe handle and has an outer surface which is thermally coupled to the inner surface of the probe housing. Heat is thereby coupled evenly from the heatspreader into the housing without the development of hotspots in the housing which could be uncomfortable to the hand of the sonographer.

Abstract: A diagnostic imaging device includes a signal processing circuit (22) processes signals from a detector array (16) which detects radiation from an imaging region (20).

A plurality of time to digital converters (40) receive the hit signals and generate a digital time stamp.

Abstract: A remote command center for providing services to geographically dispersed hospitalized patients. A datastore accessible to the remote command center receives patient data from geographically dispersed hospitalized patients. Monitored data elements of geographically dispersed hospitalized patients are also received at the remote command center and stored in the datastore. A smart alert module generates and applies patient specific rules to data elements. If a patient-specific rule for a hospitalized patient has been contravened, an alert is issued from the remote command center. A patient care module displays selected data elements of the hospitalized patients. A decision support module applies decision support algorithms to selected data elements of a hospitalized patient and to user input to provide patient care advice. Patient care advice comprises a diagnosis, a method of treatment, and a laboratory protocol.
