A mammography apparatus includes a diagnostic image acquisition unit that acquires a diagnostic image in which a calcification as a biopsy target is marked; a scout image acquisition unit that acquires a scout image obtained by imaging a mamma undergoing the biopsy from a specific direction; and a display unit that highlights a calcification (candidate for biological tissue examination) in the scout image which matches at least the marked calcification in the diagnostic image.

An apparatus includes a processing device in operative communication with an ultrasound device. The processing device is configured to: receive a user selection of a lung imaging preset option and a user-selected imaging depth for the ultrasound device; define a threshold imaging depth based on a shallow lung imaging mode and a deep lung imaging mode (the threshold imaging depth is between approximately 4 cm and 8 cm); after receiving the user selection of the user-selected imaging depth, compare the user-selected imaging depth with the threshold imaging depth; and automatically configure the ultrasound device to switch between the shallow lung imaging mode and deep lung imaging mode, depending upon a result of the comparison of the user-selected imaging depth with the threshold imaging depth.

A method for automatically determining a depth of a vascular feature on an ultrasound image feed, acquired from an ultrasound scanner comprises displaying, on a screen that is communicatively connected to the ultrasound scanner, the ultrasound image feed comprising ultrasound image frames of a region of interest comprising the vascular feature, activating a Doppler mode of the ultrasound scanner, in which the ultrasound scanner obtains a Doppler-mode ultrasound signal corresponding to the region of interest comprising the vascular feature, applying at least one image processing filter to preserve the Doppler-mode ultrasound signal (the “preserved Doppler-mode signal”), generating from the preserved Doppler-mode signal of the vascular feature as returned to the ultrasound scanner, the depth of the vascular feature and indicating depth of the vascular feature to a user of ultrasound scanner

A method and system for monitoring ultrasound tests and notifying users about test results, are described. The method includes receiving ultrasound test data representing blood flow in a blood vessel, and receiving a notification condition having a flow parameter threshold for the blood flow. The method includes determining whether the ultrasound test data meets the notification condition, and transmitting, in response to the ultrasound test data meeting the notification condition, a notification. The notification is sent in real-time, concurrently with the ultrasound test, and includes a selectable reference to cause the display of the test results on a user device. Other embodiments are also described and claimed.

Systems and methods for non-invasively estimating right ventricular pressure are provided. Tricuspid regurgitation echocardiography Doppler signals can be acquired utilizing sonography. Digitization and interpolation of the tricuspid regurgitation Doppler signals can be utilized to estimate tricuspid regurgitation and right ventricular pressure and/or provide a metric for signal quality (quality control) as well as increase confidence in the right ventricular pressure estimates.

Within the field of elastography, a new approach analyzes the limiting case of shear waves established as a reverberant field. In this framework, it is assumed that a distribution of shear waves exists, oriented across all directions in 3D (e.g. 2D space+time). The simultaneous multi-frequency application of reverberant shear wave fields can be accomplished by applying an array of external sources that can be excited by multiple frequencies within a bandwidth, for example 50, 100, 150, . . . 500 Hz, all contributing to the shear wave field produced in the liver or other target organ. This enables the analysis of the dispersion of shear wave speed as it increases with frequency, indicating the viscoelastic and lossy nature of the tissue under study. Furthermore, dispersion images can be created and displayed alongside the shear wave speed images. Studies on breast and liver tissues using the multi-frequency reverberant shear wave technique, employing frequencies up to 700 Hz in breast tissue, and robust reverberant patterns of shear waves across the entire liver and kidney in obese patients are reported. Dispersion images are shown to have contrast between tissue types and with quantitative values that align with previous studies.

The processor is configured to perform control for notifying the information.

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.
