Systems and methods for multi-level vascular imaging for construction and display of vasculature from large to small vessels and micro-vessels using a combination of varying resolution contrast enhanced ultrasound flow imaging modalities are disclosed. While one or more resolution flow imaging modes may be employed for imaging large to small vessels of a vascular tree within a large region of interest, a high resolution mode, such as super resolution imaging, constructed for delineation of the microvascular morphology and directional microcirculation is provided within one or more small ROIs placed in selected locations within the larger ROI.

Controlling an image appearance in ultrasound system comprises: providing a set of image appearance feature control parameters, each of which relates to an image appearance feature according to a pre-defined relation between a value scale of the said image appearance feature control parameter and an image appearance related to a certain condition of the corresponding image appearance feature; generating a function between the value of each image feature control parameter and the value of the standard workflow setting parameters of a combination of standard workflow setting parameters influencing the said image appearance feature; and varying automatically the value of the one or more of the standard workflow setting parameters of the combination of standard workflow setting parameters influencing an image appearance feature as a function of a variation of the value of the corresponding image appearance feature control parameters for obtaining the requested image appearance feature variation.

The present disclosure discloses methods, systems, and computer readable mediums for ultrasonic imaging. The method may include determining a target imaging mode according to information related to one or more imaging demands. The method may further include obtaining a target imaging result by performing an imaging operation according to the target imaging mode, wherein the one or more imaging demands may at least include a demand related to an imaging quality and/or a frame rate, the target imaging mode may include a first target imaging mode and/or a second target imaging mode, the first target imaging mode may be configured to perform an optimized imaging for a local imaging region, and/or the second target imaging mode may be configured to utilize a hybrid wave with at least two transmission beam types and/or at least two transmission frequencies for imaging.

A multiple aperture ultrasound imaging system may be configured to store raw, un-beamformed echo data. Stored echo data may be retrieved and re-beamformed using modified parameters in order to enhance the image or to reveal information that was not visible or not discernible in an original image. Raw echo data may also be transmitted over a network and beamformed by a remote device that is not physically proximate to the probe performing imaging. Such systems may allow physicians or other practitioners to manipulate echo data as though they were imaging the patient directly, even without the patient being present. Many unique diagnostic opportunities are made possible by such systems and methods.

Examples relate to a method for processing beamformed data of a medium. The beamformed data includes a first set of beamformed data associated with a first spatial region and a second set of beamformed data associated with a second spatial region, and the method includes estimating the clutter caused by the second spatial region at the first set.

Provided is a method of adjusting brightness of an ultrasound image including: generating at least one first image representing a region of interest (ROI) by using echo signals corresponding to ultrasound waves irradiated toward the ROI; adjusting brightness of the at least one first image based on an external signal for selecting at least one selected from a plurality of prestored gradation data and a plurality of prestored image data; and generating a second image representing the ROI based on the adjusted brightness.

A scanner transmits and receives ultrasonic waves at a specified pulse repetition frequency (PRF). A storage stores received signals acquired through the transmission and reception. A calculator generates a Doppler spectrum image by executing frequency analysis on the received signals. A display displays the Doppler spectrum image. When a desired Doppler velocity range for the displayed Doppler spectrum image is inputted, a processor reads out the received signals from the storage, and executes a resampling process on the read-out received signals at a sampling frequency corresponding to the desired Doppler velocity range. The calculator generates a new Doppler spectrum image by executing frequency analysis corresponding to the desired Doppler velocity range on the received signals having been subjected to the resampling process by the processor. The display displays the new Doppler spectrum image.

An ultrasound imaging system provides for defining a VOI in an ultrasound imaging space. The system defines an initial frame of the VOI in the ultrasound imaging space, receives a selection of at least one reference point at an arbitrary location in the ultrasound imaging space, creates at least one curved surface using at least one element of the initial frame and the at least one reference point, and then creates VOI based on the curved surface in the ultrasound imaging space.

A system and method for predicting an ultrasound image depth selection is provided. The method may include presenting, at a display system, ultrasound image data acquired according to an initial depth setting. The method may include receiving a user input adjusting a zoom level of the ultrasound image data presented at the display system. The method may include processing the ultrasound image data presented at the display system to instantaneously and smoothly transition to the adjusted zoom level in response to the user input. The method may include receiving a user input selecting a selected zoom level of the ultrasound image data presented at the display system. The method may include determining a modified depth setting corresponding to the selected zoom level. The method may include acquiring updated ultrasound image data based on the modified depth setting for display at the display system.

The invention provides a method of stabilising an ultrasound image, the method comprising generating a composite image of a current image and at least one previous image. The composite image has a region of interest which is stabilised based on at least obtained stabilisation information. Use of a current image and at least one previous image allows a composite image of a larger size to be produced.
