A medical information processing system in an embodiment includes processing circuitry. The processing circuitry acquires an ultrasound image including an observation target and having additional information, positional information indicating a position of an ultrasound probe in a subject at time of collection of the ultrasound image, and a reference image obtained by taking an image of a region including the observation target at a time point other than the time of collection. The processing circuitry generates, based on the positional information, correspondence information in which the ultrasound image and the reference image are associated with each other. The processing circuitry causes an output unit to output the generated correspondence information.

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.

Systems and methods are disclosed for an ultrasound system. In various embodiments, a system is configured to receive echo data corresponding to a detection of an echo of a pulse signal, generate a set of transformations based on the echo data, and generate a set of point estimates for a frequency dependent filtering coefficient of a spectral response. The system is further configured to extract a set of attenuation coefficients based on the set of point estimates for the frequency dependent filtering coefficient and generate image data for the material of interest based on the set of attenuation coefficients.

An ultrasound diagnostic apparatus and a control program for an ultrasound diagnostic apparatus. According to an embodiment, the ultrasound diagnostic apparatus includes an ultrasound probe that transmits and receives ultrasound waves to and from a subject in three dimensional space, a position sensor, and a processor. The processor is configured to determine whether or not a first region and a second region configure the same three dimensional region across a first scanning surface and a second scanning surface. The processor is configured to perform, based on the determining result, processing to obtain information representing the size of the three dimensional region in a direction intersecting the first scanning surface and the second scanning surface. The processor is configured to perform control for notifying the information.

A mammography apparatus includes a compression control unit that, in a case in which continuous imaging that captures a radiographic image of the breast compressed by a compression plate and then captures an ultrasound image of the breast while maintaining the compressed state is performed, performs control to set a force of the compression plate compressing the breast to a first force in the capture of the radiographic image and to change the force of the compression plate compressing the breast from the first force to a second force lower than the first force in the capture of the ultrasound image.

A device (10) is provided for ultrasound-based reflection and transmission tomography. The device (10) comprises: a transducer holder (14) configured to hold a plurality of ultrasonic transducers around an imaging volume (30) to be filled with an ultrasonic coupling medium, the transducer holder (14) having an opening for inserting, into the imaging volume (30), at least one part of a body to be imaged, wherein the transducer holder (14) is configured to move, during imaging of the at least one part of the body to be imaged, with respect to the body to be imaged; a support member (11) configured to support, during imaging, the body to be imaged, the support member (11) having a support-member-opening allowing access to the transducer holder (14) by the at least one part of the body to be imaged; a diaphragm (12) having a diaphragm-opening (13), the diaphragm (12) being arranged across the support-member-opening such that a center of the diaphragm-opening (13) is placed substantially at a predetermined position, wherein the diaphragm (12) comprises a material that has a higher transmissivity of ultrasound than a material of the support member (11); an outlet (15) for the ultrasonic coupling medium to flow out of the imaging volume (30) when the at least one part of the body to be imaged is inserted into the imaging volume (30) filled with the ultrasonic coupling medium and/or during imaging; and an elastic membrane (16) comprising a fluidtight material connecting the transducer holder (14) and the outlet (15) in order to guide the ultrasonic coupling medium flowing out of the imaging volume (30) towards the outlet (15).

A system for screening and diagnostics of cellular tissue includes a system controller, an ultrasound apparatus, an electromechanical positioning apparatus, and an image analyzer communicably coupled together. The electromechanical positioning apparatus includes an articulated arm, and the ultrasound apparatus includes a scan head coupled to an end of the articulated arm. The system controller controls the electromechanical positioning apparatus to move the scan head adjacent the cellular tissue while controlling the ultrasound apparatus to generate a first set of ultrasound images of the cellular tissue. The image analyzer analyzes the ultrasound images, and in response to identifying a potential abnormality, the electromechanical positioning apparatus is controlled to move the scan head to a position adjacent the location of the potential abnormality, where the electromechanical positioning apparatus and the ultrasound apparatus are controlled to generate a second set of ultrasound images of the potential abnormality.

A method and system acquiring, processing and displaying breast ultrasound images in a way that makes breast ultrasound screening more practical and thus more widely used, and reduces the occurrence of missing cancers in screening and diagnosis, using automated scanning of chestwardly compressed breasts with ultrasound. Enhanced, whole-breast navigator overview images are produced from scanning breasts with ultrasound that emphasize abnormalities in the breast while excluding obscuring influences of non-breast structures, particularly those external to the breast such as ribs and chest wall, and differentiating between likely malignant and likely benign abnormalities and otherwise enhancing the navigator overview image and other images, thereby reducing the time to read, screen, and/or diagnose to practical time limits and also reduce screening or diagnostic errors.

A system and method for capturing ultrasound signals from a hemispheric imaging region (e.g., by a stationary array of transducer elements arranged in the shape of a faceted hemisphere) and estimating scattering measurements that would be made by a virtual array in the opposite hemisphere (e.g., by a network of processors that receive and process the transmitted ultrasound signals in parallel) by forming an initial estimate of a medium variation for each of a plurality of subvolumes in the scattering object to form an estimated object, calculating residual scattering by using a difference between a scattering response calculated for the estimated object and measured ultrasound signals received from the scattering object, forming an initial three-dimensional image of the scattering object, and extrapolating a difference between the scattering response calculated for the estimated object and the measured ultrasound signals received from the scattering object.
