An ultrasound system according to some embodiments may include an ultrasound transducer configured to transmit ultrasound pulses toward tissue and generate echo signals responsive to the ultrasound pulses, a channel memory configured to store the echo signals, a beamformer configured to generated beamformed signals responsive to the echo signals, a neural network configured to receive one or more samples of the echo signals or the beamformed signals and produce a first type of ultrasound imaging data, and a processor configured to generate a second type of ultrasound imaging data, wherein the one or more processors may be further configured to generate an ultrasound image based on the first type of ultrasound imaging data and the second type of ultrasound imaging data and to cause a display communicatively coupled therewith to display the ultrasound image.

The present invention is capable of determining the location(s) of waste (e.g. nuclear fuel debris, obstacles, contaminated or otherwise radioactive materials), monitoring and inspecting their surroundings, and transporting them, as well as use in repair, construction, and reactor decommissioning work in high radiation environment. Ultrasound (or sound) waves are not subject to interference from radiation. This modality is utilized in the present invention to detect and image waste and/or objects of interest. The system combines the resulting ultrasound (or sound) wave images for detecting waste and/or objects of interest with radiation information acquired by a radiation detector, to generate and adjust new composite images to display. For example, the image in the direction of strong radiation is red and the image in the direction of weak radiation is blue. Additionally, the constituent imaging apparatus may be fitted on a drone or robotic system for repair and construction work.

Provided is an ultrasonic imaging apparatus capable of obtaining a more accurate shear wave elastic image by removing inefficient areas such as blood vessels using a shear wave observation signal in a section where an object is not affected by a push pulse, and a method for controlling the same. The ultrasonic imaging apparatus according to an embodiment includes: an ultrasonic probe configured to irradiate a push pulse to generate a shear wave to an object, irradiate a first observation signal to the object after the push pulse is irradiated, and irradiate a second observation signal to the object before the push pulse is irradiated or after the first observation signal is irradiated; a controller configured to determine an inefficiency region of the object based on displacement data for each region of the object obtained from the irradiated second observation signal, and generate a shear wave elastic image based on the determined inefficiency region and displacement data for each region of the object obtained from the irradiated first observation signal; and a display configured to display the generated shear wave elastic image.

Techniques, systems, and devices are disclosed for ultrasound diagnostics using spread spectrum, coherent, frequency- and/or phase-coded waveforms. In one aspect, a method includes synthesizing individual orthogonal coded waveforms to form a composite waveform for transmission toward a biological material of interest, in which the synthesized individual orthogonal coded waveforms correspond to distinct frequency bands and include one or both of frequency-coded or phase-coded waveforms; transmitting a composite acoustic waveform toward the biological material of interest, where the transmitting includes transducing the individual orthogonal coded waveforms into corresponding acoustic waveforms to form the composite acoustic waveform; receiving acoustic waveforms returned from at least part of the biological material of interest corresponding to at least some of the transmitted acoustic waveforms that form the composite acoustic waveform; and processing the received returned acoustic waveforms to produce an image of at least part of the biological material of interest.

The present disclosure describes a medical imaging and/or visualization system and method that provide a user interface enabling a user to visualize (e.g., via a volume rendering) a three dimensional (3D) dataset, manipulate the rendered volume to select a slice plane, and generate a diagnostic image at the selected slice plane, which is enhanced by depth colorized background information. The depth colorization of the background image is produced by blending, preferably based on the depth of structures in the volume, two differently colorized volume renderings, and then fusing the background image with a foreground diagnostic image to produce the enhanced diagnostic image.

According to one embodiment, an ultrasonic diagnostic apparatus includes detection circuitry and processing circuitry. The detection circuitry detects a release state of an ultrasonic probe in an active state. The processing circuitry, when the detection circuitry detects the release state of the ultrasonic probe during activation of a control mode of generating a first image based on an output from the ultrasonic probe, displaying a second image different from the first image, and displaying the first image with a predetermined opacity on the second image, perform one of control to display the second image without generating the first image, control to display the second image without displaying the first image while generating the first image, and control to generate the first image, display the second image, and display, on the second image, the first image with an opacity lower than the predetermined opacity.

For estimating attenuation, diffraction effects are corrected by transmitting at different frequencies using apertures sized to match the on-axis intensity profile and/or resolution cell size between the transmissions where there is no attenuation. Attenuation causes a variance in return. A rate of change is estimated from a ratio of the magnitude of the signals or displacements responsive to the transmissions. The attenuation is calculated from the rate of change over depth of the ratio.
