Method and system for generating a three-dimensional ultrasound image of a tissue volume from two-dimensional ultrasound images
A method may include generating a series of two-dimensional (2D) ultrasound images of the tissue volume associated with a plurality of positions along a scanning direction of the tissue volume; estimating, for each pair of consecutive 2D ultrasound images of the series of 2D ultrasound images, a distance between the positions associated with the pair of consecutive 2D ultrasound images based on a classification of a difference image generated from the pair of consecutive 2D ultrasound images using a deep neural network to produce a plurality of estimated distances associated with the plurality of pairs of consecutive 2D ultrasound images, respectively; modifying the number of 2D ultrasound images in the series of 2D ultrasound images based on the plurality of estimated distances to produce a modified series of 2D ultrasound images; and rendering the 3D ultrasound image of the tissue volume based on the modified series of 2D ultrasound images.
Systems and methods for synthetic aperture ultrasound imaging of an object
Techniques, systems, and devices are disclosed for synthetic aperture ultrasound imaging using a beamformer that incorporates a model of the object. In some aspects, a system includes an array of transducers to transmit and/or receive acoustic signals at an object that forms a synthetic aperture of the system with the object, an object beamformer unit to (i) beamform the object coherently as a function of position, orientation, and/or geometry of the transducers with respect to a model of the object, and (ii) produce a beamformed output signal including spatial information about the object derived from beamforming the acoustic echoes; a data processing unit to process data and produce an image of the object based on a rendition of the position, the orientation, the geometry, and/or the surface properties of the object, relative to the coordinate system of the array, as determined by the data processing unit.
Ultrasonic diagnostic apparatus and display method for ultrasonic inspection
A main image includes a tomographic image and a reference image as ultrasonic images. A sub-image includes a site-of-interest map and a site-of-interest list. During execution of ultrasonic inspection, each time a new site of interest is identified, a site-of-interest symbol is added to the site-of-interest map and a site-of-interest record is added to the site-of-interest list. The position of the site-of-interest symbol is determined according to the position of a probe mark.
METHODS AND SYSTEMS FOR TRACKING AND GUIDING SENSORS AND INSTRUMENTS
A shared-housing ultrasound transducer and machine-vision camera system is disclosed for registering the transducer's x, y, z position in space and pitch, yaw, and roll orientation with respect to an object, such as a patient's body. The position and orientation are correlated with transducer scan data, and scans of the same region of the object are compared in order to reduce ultrasound artifacts and speckles. The system can be extended to interoperative gamma probes or other non-contact sensor probes and medical instruments. Methods are disclosed for computer or remote guiding of a sensor probe or instrument with respect to saved positions and orientations of the sensor probe.
VARIABLE DENSITY SPATIAL SCANNING AND ELECTRO-MECHANICALLY CONTROLLED ULTRASOUND SCAN DENSITY DEVICE
An ultrasound system includes a computing device, a transducer configured to angulate through a scan region in response to a mechanical drive system that converts rotational motion generated by a motor into angular motion that angulates the transducer through the scan region, and an encoder configured to detect a rotational position of a shaft of the motor. The computing device is configured to determine an angular position of the transducer within the scan region based on the rotational position of the shaft detected by the encoder, and control generation of scan lines from the transducer based on a pulse firing pattern of scan lines to produce a predefined sequence of scan line densities across the scan region and the determined angular position of the transducer.
PROBE FOR ULTRASOUND TISSUE TREATMENT
A method and system for providing ultrasound treatment to a tissue that contains a lower part of dermis and proximal protrusions of fat lobuli into the dermis. An embodiment delivers ultrasound energy to the region creating a thermal injury and coagulating the proximal protrusions of fat lobuli, thereby eliminating the fat protrusions into the dermis. An embodiment can also include ultrasound imaging configurations using the same or a separate probe before, after or during the treatment. In addition various therapeutic levels of ultrasound can be used to increase the speed at which fat metabolizes. Additionally the mechanical action of ultrasound physically breaks fat cell clusters and stretches the fibrous bonds. Mechanical action will also enhance lymphatic drainage, stimulating the evacuation of fat decay products.
Ultrasonic diagnostic apparatus for estimating position of probe and method for controlling the same
In accordance with an aspect of the present disclosure, there is provided an ultrasonic diagnostic apparatus comprise an ultrasonic probe configured to transmit an ultrasound signal to an object and receive a response signal reflected from the object, an image generator configured to create an ultrasound image of the object based on a first ultrasound signal and a first response signal and a controller configured to control transmission order and transmission intervals of the ultrasound signal and estimate a position of the ultrasonic probe based on a second ultrasound signal and a second response signal. The ultrasonic diagnostic apparatus in accordance with embodiments of the present disclosure, the current position of the ultrasonic probe is estimated using an ultrasound signal transmitted for creation of an ultrasound image without attachment of an extra sensor, so the position of the ultrasonic probe may be estimated more economically and effectively.
Method and apparatus for synthesizing medical images
A method of synthesizing medical images includes acquiring image data of an object; generating first medical image frames of the object based on the image data; selecting, from among the first medical image frames, second medical image frames corresponding to points of time that have the same electrocardiogram (ECG) signal information of the object; generating a panoramic image by synthesizing the second medical image frames; and displaying the panoramic image on a display.
COMBINED FREQUENCY AND ANGLE COMPOUNDING FOR SPECKLE REDUCTION IN ULTRASOUND IMAGING
This disclosure relates to combined frequency and angle compounding for speckle reduction in ultrasound imaging Such combined frequency and angle compounding can result in a multiplicative speckle reduction compared to using either frequency compounding or angle compounding alone. Compounding methods of this disclosure can make use of the full aperture of the ultrasound probe when acquiring individual images, hence there can be no compromise in resolution. In disclosed embodiments, ultrasound images can be obtained while an ultrasound probe is moving and the relative position and orientation of the ultrasound images can be determined from a measurement of the position and orientation of the ultrasound probe. Certain embodiments can correct for the movement and distortion of an object being imaged during the image acquisition.
WORKFLOW ASSISTANCE FOR MEDICAL DOPPLER ULTRASOUND EVALUATION
Systems, devices, and methods are provided to provide workflow assistance to an operator during a medical imaging procedure, such as a Doppler ultrasound evaluation of a body vessel of a subject. A sensor such as a gyroscope (128) may be integrated in an external ultrasound probe (102). Workflow assistance may be provided to position the ultrasound probe (102) to make accurate flow measurements of fluid within the vessel, such as by coupling system color flow information with gyroscope angles. The workflow assistance may also assist a user in identifying a perpendicular orientation of the ultrasound to be used as a reference in making Doppler measurements. The system may also be used to create a vessel map.
