Abstract: The present invention relates to an image reconstruction system for statistically reconstructing images from transmission measurements. The image reconstruction system comprises an update equation providing unit for providing an update equation based on an iterative statistical model. The update equation comprises a data term and a regularization term. The invention proposes to not modify the regularization term, but rather the weights with which individual measurements contribute are modified on a per image voxel and per measurement basis. This is achieved by modifying the contributions of each measurement by including an additional weight on a per image voxel/per measurement basis. The additional weight for each measurement is determined by calculating the noise perpendicular to each measurement ray at each voxel position and a voxel and measurement dependent weight for each measurement, and integrated into the update equation's data term.

Abstract: An ultrasonic diagnostic imaging system is described which assesses regurgitant flow through a mitral valve by color-flow imaging. A Doppler processor produces Doppler velocity measurements of blood flow around a regurgitant valve to identify an iso-velocity surface to be used in the PISA method of regurgitant flow quantification. The velocity measurements are used to color pixels in the colorflow image and are mapped to a plurality of colors for a color bar used with the image. The color bar exhibits distinct color transitions at one or more velocities in the velocity range of the color bar which distinctively identify an iso-velocity surface in the colorflow image. The color bar may be formed with an aliasing velocity in the middle of the bar, between a zero velocity reference color of the bar and an end of the bar, and the aliasing velocity aligned with a desired iso-velocity and used to create the color transition.

Abstract: An oral care appliance (100), such as an electric toothbrush, utilizing non-linear resonant systems is described herein. In one exemplary embodiment, the oral care appliance includes a longitudinal shaft (102), a brush head (130), and a handle (190). The handle includes a motor (140) that generates a first amplitude (404) for the brush head based on the brush head being outside of the user's mouth, when no mass is applied to the brush head. In response to the brush head being inside of the user's mouth, when mass is applied, such as by pressing the brush head against the teeth, the motor causes a second amplitude (410) to be generated for the brush head that is larger than the first amplitude.

Abstract: The invention relates to an electronic device for estimating energy consumption of a person. The electronic device uses a mathematical model based on acceleration data for estimating the person's energy consumption as a function of the actual performed activity and acceleration values. The acceleration values are converted to an estimate of energy consumption of a given activity by scaling a value of time integrated acceleration data with an activity scaling parameter. The activity scaling parameters for different activities have been determined off-line by comparing measured energy consumptions over e.g. a day with estimated energy consumptions over the same period, where the estimated values are determined using the mathematical model.
