Abstract: A mechanism for adjusting the direction of one or more crossing electric fields that have been induced by a set of electrodes positioned on a patient, without necessitating movement of any of the electrodes. This is achieved through the use of one or more electrode patches, which effectively allow an electric field generator to control a position of a source/sink of an electric field, to thereby control a direction of the electric field.

Abstract: The invention relates to an imaging system for imaging a periodically moving object. An assigning unit (18) assigns ultrasound signals like A-lines to motion phases based on a provided phase signal,wherein an ultrasound images generation unit (19) generates several ultrasound images like gated M-mode images for the different motion phases based on the ultrasound signals assigned to the respective motion phase. The ultrasound images are temporally consecutively displayed on a display unit (21) for showing the periodic movement of the object (24).The resulting dynamic, movie-like image of the object allows a user like a physician to more reliably determine properties of the object like a thickness of a tissue wall, in particular, during an ablation procedure. The imaging system is therefore particularly useful for monitoring cardiac ablation procedures.

Abstract: The invention relates to an imaging system for imaging a periodically moving object. An assigning unit (18) assigns ultrasound signals like A-lines to motion phases based on a provided phase signal, wherein an ultrasound images generation unit (19) generates several ultrasound images like gated M-mode images for the different motion phases based on the ultrasound signals assigned to the respective motion phase. A selecting unit (20) is used to select an ultrasound image from the generated ultrasound images, wherein a display unit (21) displays the selected ultrasound image. The selected ultrasound image corresponds therefore to a single motion phase only such that motion artifacts in the displayed ultrasound image are reduced. The imaging system is particularly useful for, for instance, monitoring cardiac ablation procedures.

Abstract: A method and system for detecting the presence or absence of a target or desired object within a three-dimensional (3D) image. The 3D image is processed to extract one or more 3D feature representations, each of which is then dimensionally reduced into one or more two-dimensional (2D) feature representations. An object detection process is then performed on the 2D features map(s) to generate information about at least the presence or absence of an object within the 2D feature representations, and thereby the overall 3D image.

Abstract: An ultrasound image compounding method that is suitable for use with an ICE catheter that includes a first ultrasound transceiver array and a second ultrasound transceiver array, the first ultrasound transceiver array and the second ultrasound transceiver array being axially separated along a length of the ICE catheter, is described. In the method, first array data corresponding to ultrasound signals detected by the first ultrasound transducer array in response to an insonification of a region of interest by the first ultrasound transducer array at a first insonification angle; and second array data corresponding to ultrasound signals detected by the second ultrasound transducer array in response to an insonification of the region of interest by the second ultrasound transducer array at a second insonification angle; are received. A compound image corresponding to the region of interest is generating based on the first array data and the second array data.

Abstract: Images may be preprocessed to select pixels or voxels of interest prior to being analyzed by a neural network. Only the pixels or voxels of interest may be analyzed by the neural network to identify an object of interest. One or more slices may be extracted from the voxels of interest and provided to the neural network for analysis. The object may be further localized after identification by the neural network. The preprocessing, analysis by the neural network, and/or localization may utilize pre-existing knowledge of the object to be identified.

Abstract: The invention provides an ultrasound system including an ultrasound transducer array and a processor. The ultrasound transducer array comprises a plurality of transducer elements adapted to conform with a subject's body. Further, at least two ultrasound transducer elements of the plurality of transducer elements are adapted to acquire a plurality of ultrasound signals from a region of interest at different orientations relative to said region of interest. The processor is adapted to receive ultrasound signals acquired by the ultrasound transducer array. The processor is further adapted to partition the plurality of ultrasound signals according to a signal depth and, for each ultrasound signal partition, calculate a Doppler power. For each ultrasound signal, the processor identifies a depth of a fetal heartbeat based on the Doppler power of each ultrasound signal partition and identifies a fetal heart region based on the identified fetal heartbeat and a location of the at least two ultrasound transducers.

Abstract: An ablation catheter (100) for ablative treatment of ventricular tachycardia is provided. The catheter comprises a shaft (102) which is capable of being guided to the tissue to be ablated. An ablation element (104) for ablating tissue is mounted on the shaft. The catheter further comprises a plurality of ultrasound transducer arrays (106) for obtaining images of myocardial tissue. The arrays are positioned separately from each other around the circumference of the shaft. The catheter can adopt a folded configuration and a deployed configuration. In the folded configuration, the arrays are positioned against or close to the shaft thereby facilitating insertion and guiding of the catheter. In the deployed configuration, the arrays are more separated from the shaft than in the folded configuration. Further provided is a catheter arrangement including the ablation catheter, and a system for providing ablative treatment comprising the ablation catheter or catheter arrangement.
