INTELLIGENT MEASUREMENT ASSISTANCE FOR ULTRASOUND IMAGING AND ASSOCIATED DEVICES, SYSTEMS, AND METHODS
Ultrasound image devices, systems, and methods are provided. An ultrasound imaging system comprising a processor circuit in communication with an ultrasound transducer array, the processor circuit configured to receive, from the ultrasound transducer array, a set of images of a three-dimensional (3D) volume of a patients anatomy including an anatomical feature; obtain first measurement data of the anatomical feature in a first image of the set of images; generate second measurement data for the anatomical feature in one or more images of the set of images by propagating the first measurement data from the first image to the one or more images; and output, to a display in communication with the processor circuit, the second measurement data for the anatomical feature.
ULTRASOUND DIAGNOSTIC APPARATUS AND STORAGE MEDIUM
An ultrasound diagnostic apparatus includes: an image generator that generates ultrasound image data based on a reception signal received from an ultrasound probe that sends and receives ultrasound waves; a fastener that attaches the ultrasound probe to a subject and fastens the ultrasound probe on the subject such that a pressure applied to the subject to which the ultrasound probe is attached is adjustable; and a hardware processor. The hardware processor controls driving of the fastener, based on difference information between before fastening the ultrasound probe and during/after fastening the ultrasound probe, the difference information being on at least one of positional information on a position of an observation target of the subject, angle information on an angle of the observation target, and pressure information on a pressure applied to the subject.
ULTRASOUND DIAGNOSTIC APPARATUS AND CONTROL METHOD OF ULTRASOUND DIAGNOSTIC APPARATUS
Provided is an ultrasound diagnostic apparatus including an ultrasound probe, an imaging section that images the subject on the basis of a reception signal output from the ultrasound probe to generate an ultrasound image, an image analysis section that performs image analysis using the ultrasound image, a movement detection sensor that detects and outputs a movement of the ultrasound probe as a detection signal, a movement amount calculation section that calculates a movement amount of the ultrasound probe in a case where an imaging inspection portion that is currently being imaged among a plurality of inspection portions of the subject is inspected, using the detection signal output from the movement detection sensor, and a portion discrimination section that discriminates the imaging inspection portion on the basis of an image analysis result in the image analysis section and the movement amount calculated by the movement amount calculation section.
NONINVASIVE TISSUE DISPLACEMENT CONTROL AND MONITORING FOR NEUROMODULATION
The subject matter of the present disclosure generally relates to techniques for neuromodulation that include applying energy (e.g., ultrasound energy) into an internal tissue to cause tissue displacement and identifying that the tissue displacement has occurred. In one embodiment, the presence of tissue displacement is associated with a desired therapeutic or physiological outcome, such as a change in a molecule of interest.
ANATOMICAL FEATURE EXTRACTION AND PRESENTATION USING AUGMENTED REALITY
An ultrasound probe captures real-time images of patient anatomy, which are analyzed by a processor to extract salient features pertaining to an anatomical structure. By tracking the location and orientation of the ultrasound probe, a model of that anatomical structure can be created. A visual indication of the position of segments of the anatomical structure can be presented holographically to a user of an augmented reality headset to provide information extracted from the ultrasound imaging, such as holographic display of a model of the anatomical structure at the approximate location of the visual field of the headset corresponding to the physical location of the actual anatomy being viewed by a user, without presenting the entirety of the ultrasound image to the user.
SYSTEMS AND METHODS FOR ACQUIRING ULTRASONIC DATA
Methods for acquiring ultrasonic data from a scanner constructed for B-mode scans are disclosed. An image-acquiring system is provided. A three-dimensional target region is selected. A model of the target region comprising a plurality of target locations representing a plurality of planned locations in the target region at which ultrasonic data is to be acquired is created, and a visual representation of the model comprising a plurality of graphical elements is displayed. Ultrasonic data at each of the planned locations is acquired. A transformation of the visual representation is executed, comprising: performing a data quality test at each target location; for any target location that fails the data quality test, altering a graphical element corresponding to the failed target location to indicate failure of the data quality test at that location; and displaying a transformed visual representation comprising updated graphical elements on the visual display
PHYSIOLOGY SENSING INTRALUMINAL DEVICE WITH POSITIONING GUIDANCE AND ASSOCIATED DEVICES, SYSTEMS, AND METHODS
An intraluminal sensing system is provided that includes an intraluminal device. The intraluminal device has a flexible elongate member configured to be positioned within a body lumen of a patient, and an ultrasound sensor at a distal portion of the flexible elongate member. The ultrasound sensor is configured to emit an ultrasound pulse in a longitudinal within the body lumen, and to receive Doppler-shifted echoes from the ultrasound pulse. A processor circuit in communication with the ultrasound sensor is configured to: compute a velocity spectrum of particles moving within the body lumen based on the Doppler-shifted echoes; identify features in the velocity spectrum indicative of a lateral position or angular alignment of the ultrasound sensor within the body lumen; and output, to a display in communication with the processor circuit, positioning guidance for the intraluminal device based on the identified features in the velocity spectrum.
Ultrasound imaging apparatus for registering ultrasound image with image from another modality and method of operating ultrasound imaging apparatus
Provided are an ultrasound imaging apparatus and an operation method for registering an ultrasound image and an image from another modality. The ultrasound imaging apparatus may register the ultrasound image and the image from the other modality based on a three-dimensional positional relationship between at least one external electromagnetic sensor attached to a patient's body and an ultrasound probe and on a position of a feature point extracted from the image from the other modality.
CONTACT ASSESSMENT FOR BALLOON CATHETER
In one embodiment, a medical system includes a catheter configured to be inserted into a cavity of a body of a living subject, and including an inflatable balloon comprising electrodes, the inflatable balloon being configured to press the electrodes against tissue of the cavity and at least partially block blood flow in the cavity, an ultrasound probe configured to provide velocity measurements of the blood flow in the cavity over time, a processor configured to assess a quality of contact of the electrodes with the tissue responsively to at least one of the velocity measurements of the blood flow in the cavity, and output an indication of the quality of contact to an output device, and a power supply configured to provide at least one electrical signal to the electrodes in order to ablate the tissue of the cavity.
