Abstract: The present invention relates to determining the rotation of an interventional device in an ultrasound field. An interventional device is provided that is suitable for being tracked in an ultrasound beam of a beamforming ultrasound imaging system by correlating transmitted ultrasound signals from the beamforming ultrasound imaging system as detected by ultrasound receivers attached to the interventional device with the beamforming beam sequence of the ultrasound signals. The interventional device includes a longitudinal axis (A-A′), a first linear sensor array (12) comprising a plurality of ultrasound receivers (R1 . . . n) wherein each ultrasound receiver has a length (L) and a width (W), and wherein the array extends along the width (W) direction. Moreover the first linear sensor array (12) is wrapped circumferentially around the interventional device with respect to the axis (A-A′) such that the length (L) of each ultrasound receiver is arranged lengthwise with respect to the axis (A-A′).

Abstract: A method for monitoring fetal health. The method of the present disclosure comprises transmitting (100) an ultrasound signal from an at least one transducer element in an array towards a maternal abdomen. An at least one ultrasonic echo signal corresponding to an at least one depth of the maternal abdomen is then received (102) by the at least one transducer element. The at least one Doppler signal is determined after the echo is received by the at least one transducer element is then processed (104) in an at least one channel. A multidimensional map is then generated (106) from the processed Doppler signal. A feedback (114) to reposition the at least one transducer element is then provided when the fetal heart is determined to lie outside an ultrasound beam volume.

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: 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: The invention provides a system (1) for determining an identification characteristic of a medical device (3) carrying at least an ultrasound emitter/sensor element (321). The identification characteristic is based on a detection signal from the ultrasound emitter/sensor element (321) upon a drive signal. The system (1) can identify the medical device from a database (211,511) of known medical devices. Furthermore, the system (1) can update the duration and frequency of use of the medical device (3) and it can prohibit further use of the medical device (3) when a predetermined limit of use is exceeded.

Abstract: A mechanism for determining a shape of an interventional device. A mapping function is used to predict the position of an electrode, mounted on the interventional device, as the interventional device is moved within an anatomical cavity—to thereby form a sequence of predicted positions. The sequence of predicted positions is then processed to predict a shape of the interventional device.

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: A mechanism for registering ultrasound images with an anatomical map generated using a dielectric imaging process. The positions of electrodes that move with the ultrasound probe are monitored using the same dielectric imaging system that generated the anatomical map. The position at which ultrasound images are generated is captured, and this information is used to register the ultrasound image(s) with respect to the anatomical map.

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 ultra- sound 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.
