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 non-transitory computer-readable medium (CRM) storing computer program code executed by a computer processor that executes a process of acquiring a medical image generated based on a signal detected by a catheter inserted to a lumen organ, estimating a position of an object at least included in the acquired medical image by inputting the medical image to a first learning model for estimating a position of an object included in the medical image, extracting from the medical image an image portion by using the estimated position of the object as a reference, and recognizing the object included in the extracted image portion by inputting the image portion to a second learning model for recognizing an object included in the image portion.

A portable ultrasonic diagnostic apparatus and a method of controlling the same are provided, including a flexible display and a controller which changes a layout of an image displayed on the flexible display. An image necessary for diagnosing an object is appropriately disposed on a flexible display according to a situation, and thus, the user can intuitively determine an ultrasonic image.

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.

Methods for treating skin and subcutaneous tissue with energy such as ultrasound energy are disclosed. In various embodiments, ultrasound energy is applied at a region of interest to affect tissue by cutting, ablating, micro-ablating, coagulating, or otherwise affecting the subcutaneous tissue to conduct numerous procedures that are traditionally done invasively in a non-invasive manner. Methods of lifting sagging tissue are described.

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.
