    Abstract: A computer-implemented method of determining image perspective score values (s1) for X-ray projection images (110) representing a region of interest (120) in a subject, is provided. The method includes: receiving (SI 10) a plurality of X-ray projection images (110), the X-ray projection images representing the region of interest (120) from a plurality of different perspectives of an X-ray imaging system (130) respective the region of interest; inputting (S120) the X-ray projection images into a neural network (NN1); and in response to the inputting, generating (S130) a predicted image perspective score value (s1) for each of the X-ray projection images.

    Abstract: A controller (220) for determining a shape of an interventional medical device in an interventional medical procedure based on a location of the interventional medical device includes a memory (221) that stores instructions and a processor (222) that executes the instructions. The instructions cause a system (200) that includes the controller (220) to implement a process that includes obtaining (S320) the location of the interventional medical device (201) and obtaining (S330) imagery of a volume that includes the interventional medical device. The process also includes applying (S340), based on the location of the interventional medical device (201), image processing to the imagery to identify the interventional medical device (201) including the shape of the interventional medical device (201). The process further includes (S350) segmenting the interventional medical device (201) to obtain a segmented representation of the interventional medical device (201). The segmented representation of the interventional medical device (201) is overlaid (S360) on the imagery.

    Abstract: A controller for reducing noise in an ultrasound environment includes memory that stores instructions; and a processor that executes the instructions. When executed by the processor, the instructions cause the controller to execute a process that includes controlling emission, by an ultrasound probe, of multiple beams each at a different combination of time of emission and angle of emission relative to the ultrasound probe. The process also includes identifying repetitive noise from a first source received with the imaging beams at a sensor on an interventional medical device, including a rate at which the repetitive noise from the first source repeats and times at which the repetitive noise from the first source is received. The process also includes interpolating signals based on the imaging beams received at the sensor to offset the repetitive noise from the first source at the times at which the repetitive noise from the first source is received.

    Abstract: A controller (250) for identifying out-of-plane motion of a passive ultrasound sensor (S1) relative to an imaging plane from an ultrasound imaging probe includes a memory (391) that stores instructions and a processor (392) that executes the instructions. When executed by the processor, the instructions cause a system that includes the controller (250) to implement a process that includes obtaining (S710), from a position and orientation sensor (212) fixed to the ultrasound imaging probe (210), measurements of motion of the ultrasound imaging probe (210) between a first point in time and a second point in time. The process implemented by the controller (250) also includes obtaining (S720) intensity of signals received by the passive ultrasound sensor (S1) at the first point in time and at the second point in time based on emissions of beams from the ultrasound imaging probe (210), and determining (S730), based on the measurements of motion and the intensity of signals, directionality of and distance from the passive ultrasound sensor (S1) to the imaging plane.

    Abstract: An ultrasound (US) system (10) includes a US scanner (14) and a US probe (12) operatively connected to the US scanner. At least one electronic processor (20) is programmed to: control the US scanner and US probe to acquire a series of preoperative images of a tumor and surrounding blood vessels in a region of interest (ROI) of a patient; provide a graphical user interface (GUI) (26) via which the acquired preoperative images are labeled with contours of the tumor and the surrounding blood vessels in the ROI; tune a trained neural network (30) for the patient using the labeled preoperative images to generate a patient-tuned trained neural network; perform live imaging by controlling the US scanner and US probe to acquire live images of the tumor and the surrounding blood vessels in the ROI of the patient; input the live images to the patient-tuned trained NN to output live contours of the tumor and the surrounding blood vessels; and control a display device (24) to display the live images with the live contours superimposed.
