摘要： A method and a device for measuring blood pressure and heart rate is disclosed. Blood pressure signals corresponding to the Korotkoff sounds are detected using an array of primary acoustic sensors. A secondary acoustic sensor is used for detecting noise and vibrations. The signals provided by the primary acoustic sensors are then processed using adaptive linear beamforming and are combined into a single signal. The combined signal is then provided to an adaptive interferer canceller together with the signal of the secondary acoustic sensor for removing noise and vibration effects. Artifacts due to a patient's motion are removed in a following post-processing step. The post-processed signal and the pressure signal are then graphically displayed enabling a trained user to correct the automatic measurement, to decide whether a repeat measurement is necessary, and to quickly and accurately diagnose heart pulse patterns.

摘要： The present invention relates to a method for blind reconstruction of multi-frame image data. Multi-frame image data corresponding to at least two image frames are received. Using a filter function the image data corresponding to each of the at least two image frames are filtered. The filtered image data are then classified producing data indicative of a classified image for each of the at least two image frames. In a following step the filtered image data are fusion-based classified producing data indicative of a classified fused image. By superposing the corresponding data indicative of the classified image with the data indicative of the classified fused image an error function is determined for each of the at least two image frames. Using the error function the filter function for each of the at least two image frames is then updated. This process is repeated until a stopping criterion is met. After stopping the iteration reconstructed image data based on the filtered image data of at least one of the at least two image frames are provided.

摘要： A method and a device for measuring blood pressure and heart rate in an environment comprising extreme levels of noise and vibrations is disclosed. Blood pressure signals corresponding to the Korotkoff sounds are detected using an array of primary acoustic sensors, placed on the patient's skin over the brachial artery. A secondary acoustic transducer is placed on the outside of a pressure cuff the patient away for detecting noise and vibrations. Pressure is applied to the artery using the pressure cuff forcing the artery to close. The pressure is then reduced and while reducing the pressure the acoustic signals detected by the first and second acoustic sensor as well as a signal indicative of the pressure applied to the artery are provided to a processor. The signals provided by the primary acoustic sensors are then processed using a combination of focused beamforming and planar wave beamforming. The final beam time series is then processed using an adaptive interferer canceller algorithm with the signal provided by the secondary acoustic sensor as interferer. Use of an array of acoustic sensors in combination with beamforming substantially enhances signal detection as well as accurate isolation of the signal source which is highly beneficial for blood pressure measurements measurements performed under extreme levels of noise and vibrations.

摘要： An adaptive multidimensional beamformer having near-instantaneous convergence for ultrasound imaging systems deploying multidimensional sensor arrays is disclosed. In a first step, the multidimensional beamformer is decomposed into sub-apertures. Each sub-aperture is then again decomposed into two coherent subsets of circular and/or line array beamformers in different coordinate directions of the multidimensional array. Implementation of the multidimensional beamformer according to the present invention provides the basis for a 3D ultrasound imaging system according to the present invention comprising a compact multidimensional sensor array and a compact processing unit that is field deployable and generates high resolution three-dimensional images in real time. It is also possible to capture four-dimensional images, the fourth dimension being time and the resulting images forming a video image of a volume of a moving organ.

摘要： A microwave thermography apparatus to measure temperatures within a dielectric body comprises a partial ellipsoidal cavity with an electrical conductive surface wherein the body can be located at one focus of the cavity. A microwave antenna located at a second focus of the cavity is connected to a radiometer. That radiometer amplifies and filters signals from the antenna before they are applied to a detector with the temperature of the body being determined from the voltage amplitude of the detected signals.

摘要： A method of tracking organ motion and removing motion artifacts in conventional computer tomography scans is disclosed. Sensor time series indicative of projection measurement data of the object are correlated using a software spatial overlap correlator method in order to obtain a sinogram indicative of organ motion. The software spatial overlap correlator method is based on the fact that the image sampling process of a computer tomography scanner is periodical, therefore, image samples taken at a time t and at a time t+T are taken from identical spatial locations. The sinogram is then processed using a retrospective gating method or a coherent sinogram synthesis method in order to correct the image data for motion effects. This method for motion correction is software based and, therefore, can be easily implemented in existing computer tomography systems without major hardware modification.
