Abstract: A dual frequency ultrasound transducer includes a high frequency ultrasound array and a low frequency transducer positioned behind or proximal to the high frequency ultrasound array. In one embodiment, a dampening material is positioned between a rear surface of the high frequency array and the a front surface of the low frequency array. The dampening preferably is high absorbing of signals at the frequency of the high frequency array but passes signals at the frequency of the low frequency transducer with little attenuation. In additional, or alternatively, the low frequency can angled with respect to the plane of the high frequency transducer to reduce inter-stack multipath reflections. Beamforming delays compensate for the differences in physical distances between the elements of the low frequency transducer and the plane of the high frequency transducer.

Abstract: In one embodiment, a photoacoustic imaging system receives user input to specify one or more imaging wavelengths, and a target number of image frames to be taken of a target tissue region. The specified imaging wavelengths are set to capture at least two different photoabsorbing molecules in the target tissue. The photoacoustic imaging system takes image frames at the specified wavelengths, while the system also receives ECG and respiration data of the subject. Image frames are discarded based on the respiration data, and the other image frames are sorted into a plurality of slots corresponding to different points of the cardiac cycle from the ECG data. The system creates a composite image from the one or more wavelengths to show the target tissue of interest through the different points of the cardiac cycle.

Abstract: An ultrasound imaging system enhances the display of an ultrasound image by applying a selected style to the content of the ultrasound image. The style may be of anatomic illustrations of a particular anatomical feature such as tissue type or may be the style of a previously obtained ultrasound image that shows tissue well. The style of other imaging modes can also be applied. In some embodiments, a training mode of the ultrasound imaging system implements a style transfer technique to enhance the appearance of captured ultrasound image data.
Abstract: An ultrasound imaging system includes a processor to associate an ultrasound image with one or more pictographs that correspond to the image. A processor provides ultrasound image data to one or more trained neural networks that classify the image data. The processor is programmed to select one or more pictographs that correspond to the classified image data for presentation to the operator. In some embodiments, the processor is programmed to use a neural network to determine if an ultrasound image captured during an examination corresponds to one or more required views for a particular type of examination.

Abstract: Ultrasound imaging systems including transducer probes having wireless tags, and associated systems and methods, are described herein. For example, the wireless tags can store supplemental data about the transducer probes, and the ultrasound system can include a base unit configured to wirelessly communicate with nearby ones of the wireless tags to receive the supplemental data. The base unit can be further configured to display the transducer probes that are nearby. In some embodiments, the operator can filter or sort the displayed nearby transducer probes based on the supplemental data to identify a particular one of the nearby transducer devices that has one or more desired attributes.

Abstract: Provided are a photoacoustic image generation apparatus and an insert that can evaluate whether a plurality of materials with different absorption wavelengths are present in the vicinity of a puncture needle, without preparing a plurality of light sources. A puncture needle is at least partially inserted into a subject. An optical fiber guides light with a first wavelength. A light emitting portion emits the light guided by the optical fiber. A light absorption/conversion member absorbs the light with the first wavelength emitted from the light emitting portion and converts the light with the first wavelength into light with a second wavelength. In addition, the light absorption/conversion member generates photoacoustic waves with the conversion into the light with the second wavelength.
Abstract: A processor in an ultrasound imaging system identifies faults or errors in the system. In one embodiment, fault or error conditions are detected by monitoring system parameters during a self-test. In another embodiment, a processor provides ultrasound image data to a trained neural network to identify fault conditions in a transducer or the imaging system. In some embodiments, the processor makes adjustments to one or more operating parameters to compensate for the identified fault conditions so that the system continues to operate and produce images with the detected fault condition.
Abstract: An ultrasound imaging system includes a thermally conductive frame and a number of electronic components and a display that are sealed within the frame. The frame further includes a plenum extending through the frame with surfaces that are thermally coupled to the electronic components and the display. An active cooling mechanism, such as one or more fans, moves air through the plenum to remove heat generated by the electronic components and display. The plenum is environmentally sealed so that moisture, dust, air or other contaminants drawn into the plenum do not contact the sealed electronic components and display in the frame.
Abstract: A method and apparatus are disclosed herein for controlling an ultrasound machine using one or more touchless inputs. In one embodiment, the method for controlling operation of the ultrasound machine comprises obtaining one or more touchless inputs; determining one or more operations to control the ultrasound machine based on the one or more touchless inputs and machine state of the ultrasound machine; and controlling the ultrasound machine using the one or more operations.
Abstract: A dual frequency ultrasound transducer includes a high frequency (HF) transducer and a low frequency (LF) transducer that is positioned behind the high frequency transducer.
