A processor acquires a composite two-dimensional image and region-of-interest information including information of a tomographic image corresponding to a region of interest on the composite two-dimensional image, displays a schema that schematically shows a breast and the composite two-dimensional image, and displays positions of the region of interest in the displayed schema and composite two-dimensional image in association with each other.

Various methods and systems are provided for reducing an amount of time and resources spent on reviewing digital breast tomosynthesis (DBT) images and corresponding synthetic 2D images. In one example, a method includes receiving a plurality of tomosynthesis data studies, each study comprising a first image set of synthetic two-dimensional (S2D) images, a second image set of slab images, and a third image set of plane images. For each study of the plurality of tomosynthesis data studies, a minimum dataset to be reviewed by a radiologist is determined based on an analysis of the tomosynthesis data by an AI-based system, and the minimum dataset is displayed on a display device rather than the plurality of tomosynthesis data studies.

A method and system for real‑time fluoroscopy guidance in robotic interventions. A tomosynthesis sweep of 2D fluoroscopic projections is used to reconstruct a 3D image of a target. The 3D target is projected as an overlay into live fluoroscopy frames. A best‑matching tomosynthesis projection is selected and a reference feature common to the reference projection and live frames is localized. Displacement of the reference feature is computed and compared to thresholds to determine whether the subject's physical state has changed and whether the overlay remains correctly positioned. The system provides qualitative indicators, recommends retake of tomosynthesis when misalignment exceeds tolerance, and can pause or limit robotic tool advancement until alignment is restored. Adaptive thresholding using a trained model is supported.

A computer-implemented method for predetermining a location and / or a thickness of a slice, to be imaged of a patient during a tomosynthesis imaging to be parameterized by an imaging facility comprising the steps of obtaining three-dimensional image data of a preceding tomosynthesis imaging or of another three-dimensional imaging of the patient, wherein the three-dimensional image data depicts at least one part of an object located at least partly within the patient, evaluating the three-dimensional image data for establishing the location of a longitudinal axis of the object along which the part of the object extends, and establishing the location and / or the thickness of the slice to be imaged as a function of the established location of the longitudinal axis in such a way that the slice to be imaged images a predetermined target position within the patient and at least one longitudinal section of the object when the longitudinal axis of the object is located in the established location.

A digital breast tomosynthesis (DBT) method includes: disposing a breast of an examination subject between an X-ray irradiator and an X-ray detector; acquiring first image data by emitting X-rays toward the breast of the examination subject; analyzing the first image data to estimate a type of breast lesion by using a pre-trained AI image diagnosis portion; determining an angular range for performing DBT according to the estimated type of breast lesion; performing the DBT in which the X-ray irradiator rotates around the breast within the determined angular range and emits X-rays toward the breast at every predetermined angular interval, to acquire second image data; and reconstructing the second image data to generate a tomosynthesis image, wherein a first dose, which is a total X-ray dose in acquiring the first image data, is smaller than a second dose, which is a total X-ray dose in performing the DBT.

The invention discloses a tomosynthesis imaging system including a guidance system with X-ray tomosynthesis registration and tracking. The imaging system may include a cone-beam tomosynthesis imaging system configured to create a 3D image of the patient's anatomy upon initiation of the input. The system may also include at least one memory device having instructions that, when executed by the at least one processor, cause the tomosynthesis imaging system to perform a plurality of actions including: obtaining a 3D image from the tomosynthesis imaging system; obtaining a previous 3D image of the patient's anatomy; and registering the 3D image with a previous 3D image to produce a synthesized 3D image. The navigation system may also include an interface system that accepts an activation input to obtain a 3D image and presents at least a portion of the synthetic 3D image for review by a supervisor.

An ultrasound diagnostic apparatus includes an ultrasound probe, an image generation unit that generates an ultrasound image on which a breast of a subject is captured by performing transmission and reception of an ultrasound beam by using the ultrasound probe for the subject, a schema image generation unit that generates a schema image on which a region of interest is plotted based on a synthesized two-dimensional image generated by using a series of radiation images obtained by tomosynthesis imaging and on which the breast of the subject is captured, information on a tomosynthesis image accompanying the synthesized two-dimensional image and corresponding to the region of interest on the synthesized two-dimensional image, and information on the region of interest, and a monitor that displays the ultrasound image, the synthesized two-dimensional image, and the schema image.

A method and system for producing tomosynthesis images of a sample placed into a cabinet x-ray system where an X-ray source delivers X-rays through a sample and forms an image at a digital X-ray detector, multiple X-ray images are taken as the X-ray source moves relative to the stationary sample, the X-ray source may move in a range from about 320° to and including about 40°, and may travel substantially along a path that generally defines an arc, or linearly, while a detector remains stationary and the source remains substantially equidistant from a specimen platform. The set of X-ray image data taken at the different points are combined to form a tomosynthesis image that can be viewed in different formats, alone or as an adjunct to conventional radiography.
