Abstract:
Methods and systems are provided for tagging and selectively saving medical imaging data. One example method includes acquiring medical imaging data with a medical imaging device, tagging a subset of the medical imaging data with a tag based on one or more features of the imaging data, and saving the subset of the imaging data if the tag matches a designated tag.

Abstract:
An ultrasound system is disclosed comprising an ultrasound transducer array (100) comprising a plurality of ultrasound transducer cells (130), each of said cell having an independently adjustable position and/or orientation such as to conform an ultrasound transmitting surface of the cell to a region of a body and a controller (140). The controller is configured to register the respective ultrasound transducer cells by simultaneously operating at least two ultrasound transducer cells in a transmit mode in which the cells transmit distinguishable ultrasound signals and operating the remaining ultrasound transducer cells in a receive mode. The controller extracts time-of-flight information of the respective ultrasound signals between transmitter and receiver and by systematically selecting different ultrasound transducer cells as transmitters, the controller collects sufficient time-of-flight information from which the respective position and/or relative orientation of the ultrasound transducer cells within the ultrasound transducer array may be derived. A method for operating the ultrasound system in this manner as well as a computer program product is also disclosed.
Abstract:
An echogenic needle may have at least one V-shaped spiral groove formed at its distal portion adjacent to its patient end. The walls of the groove are orthogonal to each other. The groove is titled at a given angle from a neutral position toward the proximal end of the needle so that when the needle is inserted into the patient at an insertion angle under ultrasound imaging, the ultrasound wave emitted from the ultrasound transducer is reflected in a substantially reverse direction back to the transducer by at least one wall of the spiral groove. A pair of crisscrossing grooves may be spirally wound about the distal portion of the needle with each groove being tilted to the given angle to enhance echogeneity. The echogeneity of the needle may also be enhanced by increasing the pitch density of each groove while maintaining the crisscrossing groves at their neutral position.
Abstract:
An ultrasound probe (104) includes a probe head (134). The probe head includes a transducer array (136) with a transducing surface (137), an instrument guide (142), and a light source (140). A method includes emitting a light beam, from a light source disposed on and adjacent to a transducer array of an ultrasound imaging probe, in a direction opposite of a transducing surface of the transducer array, at an inside wall of a cavity of a subject or object. A laparoscopic ultrasound imaging probe includes a shaft, a body, an articulating member that couples the probe head, and a handle coupled to the elongate shaft. The articulating probe head includes a transducer array that generates an ultrasound signal that traverses an image plane of the transducer array, an instrument guide, and a light source arranged to emit light in a direction opposite of the image plane.
Abstract:
A method of detection of substances embedded in a human host is provided that includes emitting from a coherent beamforming electromagnetic excitation source a spatially scanning, temporally pulsed, electromagnetic excitation signal toward a human host separated by air from the electromagnetic excitation source, where the excitation signal produces an acoustic signal by a substance, detecting the acoustic signal by a CMUT coherent phased array separated by air from the human host, analyzing the detected acoustic signal by a signal processor, and outputting by the processor substance response information according to a scanning position and according to a temporal pulse width of the electromagnetic excitation signal.
Abstract:
There are described a variety of intravascular filters have wherein at least a portion of the filter has been modified to provide an enhanced echogenic characteristic of the filter.
Abstract:
Systems and methods for obtaining and processing data collected using a multi-site intravascular sensing device are provided. Some embodiments are directed to locating a structure within a vessel and performing an examination of the structure once it has been located. In one embodiment, an elongate member has a plurality of sensors and set of measurements is obtained using the plurality of sensors, the set of measurements including at least one measurement from each sensor of the plurality of sensors. The various sensor measurements are compared and a difference in a vascular characteristic is determined from the compared measurements. The location of the structure may be determined based on the adjacent sensors.
Abstract:
The invention relates to an ultrasound data visualization apparatus for visualizing ultrasound data showing an object during an interventional procedure. A reference image (65) and a current image (68) of the object are simultaneously displayed, wherein the current image corresponds to a current time interval and the reference image corresponds to a reference time interval and wherein the current time interval and the reference time interval correspond to different phases of the interventional procedure. The current image can be shown therefore with, for instance,a relatively high temporal resolution for allowing a user to observe detailed object changes, which may be caused by the interventional procedure, while an overview over different phases of the interventional procedure can still be provided, because also the reference image is displayed and can be used by a user for comparing the current image with the reference image.
