Abstract: A co-registration system includes a processor circuit that generates and displays a first co-registration reliability indicator based on the status of an x-ray imaging device and a second co-registration reliability indicator based on the speed of an intravascular catheter/guidewire. The processor circuit receives, from the x-ray imaging device, x-ray images of a blood vessel while the intravascular catheter/guidewire moves through the blood vessel. The processor circuit receives, from the catheter/guidewire, intravascular data representative of the blood vessel while the catheter/guidewire moves through the blood vessel. The processor circuit co-registers the intravascular data to an x-ray image received from the x-ray imaging device. The processor circuit also receives a signal representative of an inactive status of the x-ray imaging device during the movement of the catheter/guidewire. The processor circuit then displays the first reliability indicator representative of the x-ray fluoroscopy device status and may indicate that co-registration is not possible. The processor circuit also determines a speed of the catheter/guidewire and displays a second indicator representative of the speed of the catheter/guidewire being too fast for reliable co-registration.

Abstract: A co-registration system includes a processor circuit that corrects the location of an indicator identifying a radiopaque portion of an intravascular catheter shown in an x-ray image and corrects the shape of a pathway defined by the movement of the radiopaque portion. The processor circuit receives, from the x-ray imaging device, x-ray images of a blood vessel while the intravascular catheter/guidewire moves through the blood vessel. The processor circuit receives, from the catheter, intravascular data representative of the blood vessel while the catheter moves through the blood vessel. The processor circuit co-registers the intravascular data to an x-ray image received from the x-ray imaging device. The processor circuit also displays the location indicator identifying the location of the radiopaque portion of the catheter in each x-ray image. In response to a user input, the processor circuit moves the location indicator to a corrected location. The processor circuit also modifies the shape of the pathway of the catheter in response to a user input. The processor circuit then completes the co-registration process again after either of these changes are made.

Abstract: The invention provides a method for determining a global confidence index for a 2D ultrasound image extracted from a 3D ultrasound volume, wherein the global confidence index indicates the suitability of the 2D ultrasound image for medical measurements. The method comprises obtaining a 3D ultrasound volume of a subject and extracting a set of at least one 2D ultrasound image from the 3D ultrasound volume. A set of geometrical indicators are then obtained with a first neural network, wherein each geometrical indicator indicates geometrical features of the anatomy of the subject. The set of 2D ultrasound images are then processed with a second neural network, wherein the output of the second neural network is a set of anatomical indicators and wherein the anatomical indicators indicate at least the presence of anatomical landmarks. A global confidence index is then determined for each one of the set of 2D ultrasound images based on the geometrical indicators and the anatomical indicators.

Abstract: Systems and methods for ultrasound image acquisition, tracking and review are disclosed. The systems can include an ultrasound probe coupled with at least one tracking device configured to determine a position of the probe based on a combination of ultrasound image data and probe orientation data. The image data can be used to determine a physical reference point and superior-inferior probe coordinates within a patient being imaged, which can be supplemented with the probe orientation data to determine lateral coordinates of the probe. A graphical user interface can display imaging zones corresponding to a scan protocol, along with an imaging status of each zone based at least in part on the probe position. Ultrasound images acquired by the systems can be tagged with spatial indicators and severity indicators, after which the images can be stored for later retrieval and expert review.

Abstract: Systems and methods for high spatial and temporal resolution ultrasound imaging of microvessels in a subject are described. Ultrasound data are acquired from a region-of-interest in a subject who has been administered a microbubble contrast agent. The ultrasound data are acquired while the microbubbles are moving through, or otherwise present in, the region-of-interest. The region-of-interest may include, for instance, microvessels or other microvasculature in the subject. By imaging microbubbles, a cross-correlation map between each microbubble image and a point spread function of the system can be generated. Accumulation of power-based cross-correlation maps may then be used to generate a high-resolution high-contrast image of the microvasculature.

Abstract: A facility for processing a medical imaging image is described. The facility applies to the image a first machine learning model trained to recognize a view to which an image corresponds, and a second machine learning model trained to identify any of a set of anatomical features visualized in an image. The facility accesses a list of permitted anatomical features for images corresponding to the recognized view, and filters the identified anatomical features to exclude any not on the accessed list. The facility causes the accessed image to be displayed, overlaid with a visual indication of each of the filtered identified anatomical features.
