Abstract: A system and method is described wherein components of the reagent (4), e.g. labelled antibodies, are separated from the biologically active sensor surface (5) by depositing the reagent (4) on a carrier surface (3) distinct from the sensor surface (5) in the detection region (2), e.g. detection chamber. In this way, a high assay reproducibility is obtained. By allowing a short, well-defined and controlled, pre-incubation time between the particles of interest, e.g. drugs, in the sample fluid (20) and the reagent (4), the reproducibility will be increased, whereas the speed of the assay is guaranteed by having all components in one detection region (2), e.g. detection chamber.

The method further includes the operation of deriving one or more 3-D model segments from each of the one or more 3-D reconstructions, wherein a plurality of 3-D model segments are formed thereby, and wherein each of the one or more 3-D model segments is derived from a single one of the one or more 3-D model segments. The plurality of derived 3-D model segments forms a 4-D reconstruction of the region of interest.

Abstract: A video system (100) comprises an input (102) for receiving a plurality of broadcast content channels. A tuner (104) generates a content signal corresponding to at least one of the broadcast content channels. A time shift buffer (106) stores the content signal generated by the tuner to provide a time shift capability. A storage means (108) for stores a profile, the profile comprising one or more preference settings, wherein a preference setting comprises at least one preferred channel and at least one corresponding time criterion, the preference setting indicating that the content signal corresponding to the preferred channel is to be stored in the time shift buffer when the corresponding time criterion is satisfied. Control means (110) cause the tuner to generate the content signal of the preferred channel in agreement with the time criterion.

Abstract: It is described an improved visualization of an object under examination (107). Thereby, original 2D rotational projections are combined preferably in an overlaying manner with corresponding viewings of a 3D reconstruction. By showing the 2D rotational projections in combination with the 3D reconstruction, 3D vessel information can be compared with the original 2D rotational image information over different rotational angles. In a clinical setup the combined visualization will allow for an easy check if findings in the 3D RA volume such as stenosis or aneurysms are not overestimated or underestimated due to e.g. an incomplete filling with contrast agent and/or a spectral beam hardening during the rotational scan.

Abstract: A method of suggesting accompaniment tracks for synchronised rendering with a content data item includes obtaining data descriptive of the content data item. A database query based at least partly on the data descriptive of the content data item to identify auxiliary content items to a user is resolved. The database (14;28) includes records, each configured to associate descriptive data with an auxiliary content data item for forming an accompaniment track. Data representative of a selection of an auxiliary content data item is received in association with the query, and a database record for the selected auxiliary content data item is caused to be amended to reflect the selection in association with at least part of the descriptive data included in the query.

Abstract: The invention relates to a light-reflecting material (240) of a radiation detector (200), which also comprises photo-detecting elements (220) and imaging elements (250) adjacent to the photo-detecting elements. Typically, epoxy resin is used as the light-reflecting material. According to the invention, a tough, pliable resin may be used for the photo-detecting elements. This has the advantage of reducing thermal stresses inside the radiation detector, thus reducing the risk of delamination due to e.g. temperature shifts. Moreover, the tough, pliable resin preferably also has a low refractive index, which may increase the scattering co-efficient of the resin as compared to epoxy resin, which has a refractive index of 1.58. The layer thickness of a low-refractive index resin may thereby be reduced as compared to the layer thickness of epoxy resin for a given level of optical crosstalk. Preferable resins are silicon resins and resins of thermoplastic fluoropolymers.

Abstract: When adapting models of anatomical structures in a patient for diagnosis or therapeutic planning, an atlas (26) of predesigned anatomical structure models or image volumes can be accessed, and a segmentation of one or more such structures can be selected and overlaid on an a 3D image of corresponding structure(s) in a clinical image (52) of a patient. A user can click on an initially unapproved segmentation 5 landmark (72) on the patient image (52), reposition the unapproved landmark, and approve the repositioned landmark. Remaining unapproved landmarks (72) are then repositioned as a function of the position of the approved landmark (92) using one or more interpolation techniques to adapt the model to the patient image on the fly.

Using the model, which is based on the physical principles of the processes occurring in the gas discharge lamp, it is possible to determine the physical state of the gas discharge lamp.

Abstract: An ultrasonic imaging apparatus and method are described for monitoring the progress of therapy for pathology such as lesions, tumors, and metastases by means of contrast agent imaging. A sequence of images are acquired as a bolus of contrast agent infuses the tissue containing the pathology. A contrast wash-in time parameter is calculated for both the tumor and normal tissue, and a ratio is calculated of the two wash-in time parameters (called WITR) which removes the effects of variations in the procedure from one therapy monitoring session to another. A difference curve of the time-intensity curves of the pathology and normal tissue is also produced, which is similarly immune to procedural variations. The motional effects of respiration can be taken into account by detecting the position of a landmark such as the diaphragm in each of the images of the sequence and discarding from processing those which exhibit a change in the position of the landmark relative to the probe.

A display incorporating the backlight is also described.

Abstract: A system and a method are described for determining a stress level of a person based on the performance of the person in a game or puzzle. First, in a calibration phase the person is asked to judge his/her currently experienced stress level (120) and the person is asked to play (130) a game or puzzle resulting in a certain performance score. Subsequently in this calibration phase, the system links (150) the indicated stress level and the performance score. By repeating these steps a number of times, the system builds a table linking game performance scores and stress levels.

Then, based on the current performance score and on the table assembled in the calibration phase, the system determines (250) the current stress level.
