    Abstract: A method for estimating an ultrasonic attenuation parameter of a region in a medium includes a transmission step in which at least one pulse is transmitted in the medium by a transducer, and a reception step in which data is acquired by a transducer in response to the pulse. The method includes a processing step in which the data is processed by the processing unit for providing backscattered acquisition data of the region, and a function determination step in which an auto-correlation function of the backscattered acquisition data is determined which is a function of depth in the spatio-temporal domain, the autocorrelation function being determined at a lag of zero. The method includes an attenuation estimation step in which an ultrasonic attenuation parameter is estimated based on said auto-correlation function. The method is implemented by a processing unit associated to at least one ultrasound transducer.

    Abstract: Systems and methods for mapping a region of interest within breast tissue utilize multiple layers of information to produce a unique digital fingerprint of breast tissue. X-ray and ultrasound imaging is combined with elastography and Doppler to create an architectural map of a breast including coordinates to mark one or more regions of interest. The architectural map can be utilized during future imaging procedures and surgeries to automatically and virtually indicate the location of previously biopsied lesions. The architectural map can be displayed on a user interface of a computing device to guide a user to the region of interest during imaging.

    Abstract: A method for compensating a depth-dependent attenuation in ultrasonic signal data of a medium and a system for performing the method. The method is implemented by a processing system (8), the method comprising the following: processing (c), in which ultrasound signal data is processed by the processing unit for providing in-phase and quadrature phase (IQ) data of the medium, and attenuation compensation (f), in which a phase of the IQ data is compensated as a function of a respective frequency shift amount for each of a plurality of different depths (z1, z2, zn) in the medium, such that the IQ data spectrum is recentered across the plurality of different depths.

    Abstract: Examples of the present disclosure describe systems and methods for implementing real-time artificial intelligence (AI) for physical biopsy marker detection. In aspects, the physical characteristics for one or more biopsy site markers may be used to train an AI component of an ultrasound system. The trained AI may be configured to identify deployed markers. When information relating to the characteristics of a deployed marker is input into the ultrasound system, the trained AI may process the received information to create one or more estimated images of the marker, or identify echogenic properties of the marker. During an ultrasound of the site comprising the deployed marker, the AI may use the estimated images and/or identified properties to detect the shape and location of the deployed marker.
