According to one embodiment, a medical image processing apparatus includes processing circuitry. The processing circuitry designates a region of interest in a first tomogram among multiple tomograms which are based on tomosynthesis imaging performed with a subject compressed in a first direction. The processing circuitry specifies a second tomogram corresponding to the region of interest from among multiple tomograms which are based on tomosynthesis imaging performed with the subject compressed in a second direction different from the first direction.

A tilted needle biopsy assembly is provided for mounting on an x-ray system. Because the biopsy needle is angled relative to at least one of the detector and the x-ray source, x-ray imaging may be performed during the biopsy procedure without interference by the biopsy device. The angled biopsy needle additionally allows improved access to the axilla and chest wall of the patient. The stereotactic biopsy device of the present invention may be coupled to any x-ray system, whether upright or prone, including but not limited to mammography systems, tomosynthesis systems, and combination mammography/tomosynthesis systems. The system flexibly supports the use of any mode of image capture (i.e., scout, two dimensional mammogram, three-dimensional reconstructed volume) for either or both target visualization and target localization. With such an arrangement, a needle biopsy assembly having improved patient coverage is provided for use with a variety of different x-ray imaging platforms.

An X-ray imaging system using multiple puked X-ray sources to perform highly efficient and ultrafast 3D radiography is presented. There are multiple puked X-ray sources mounted on a structure in motion to form an array of sources. The multiple X-ray sources move simultaneously relative to an object on a pre-defined arc track at a constant speed as a group. Electron beam inside each individual X-ray tube is deflected by magnetic or electrical field to move focal spot a small distance. When focal spot of an X-ray tube beam has a speed that is equal to group speed but with opposite moving direction, the X-ray source and X-ray flat panel detector are activated through an external exposure control unit so that source tube stay momentarily standstill equivalently. 3D scan can cover much wider sweep angle in much shorter time and image analysis can also be done in real-time.

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.

An apparatus for holding a breast compression paddle, includes a base, a lip connected to and extending substantially orthogonal from the base, an arm connected to and extending substantially orthogonal from the base and disposed substantially parallel to the lip, and a tine connected to and extending at an angle to the arm. The lip defines a lip plane, and the tine is oriented towards the lip plane. The apparatus is configured to hold and support a compression paddle.

A compression paddle with a plurality of markers is advanced towards a patient's breast which has been positioned on a support platform for an imaging procedure. An initial position of the compression paddle is detected relative to the support platform when a portion of the breast is contacted. An initial marker is identified which is associated with a feature of the breast when the compression paddle is in the initial position. A compression target marker is based at least in part on the initial position and the initial marker.

Various methods and systems are provided for mammogram imaging. In one example, a method for an x-ray mammography system includes determining, based on a pre-exposure image of a subject acquired with the x-ray mammography system before acquisition of one or more main images, that the subject has an implant; automatically adjusting one or more imaging parameters in response to determining that the subject has the implant; and acquiring the one or more main images with the adjusted one or more imaging parameters.

A control apparatus including at least one processor that is configured to: capture a low-energy image by a radiography apparatus by emitting radiation having first energy to a subject into which a contrast medium has been injected, and then sequentially acquires each of a plurality of high-energy images captured by the radiography apparatus at different timings by emitting radiation having second energy higher than the first energy to the subject into which the contrast medium has been injected, sequentially derive a body movement amount of the subject from each of the plurality of high-energy images, and perform, in a case in which the derived body movement amount exceeds a threshold value, control of causing the radiography apparatus to re-capture the low-energy image before a next high-energy image is captured.

A method includes receiving first data based on a region of interest of tissue. The first data may be captured to represent the tissue according to a first moment. The method also includes receiving second data based on the region of interest. The second data may be captured to represent the tissue according to a second moment different from the first moment. The method also includes determining features of the first data according to a first network. The first network may comprise weights. The method also includes determining features of the second data according to the weights. The method also includes determining an input based on the features of the first data and the features of the second data. The method may also include treating a patient or adjusting treatment of the patient diagnosed by one or more of these steps. An apparatus for performing the method is disclosed.

Described herein are systems, devices, and methods for aiding a user to scroll through or otherwise manipulate a stack of medical and tissue images. A system as described herein may comprise: a foot controller, configured to detect one or more of vertical and horizontal motion of a user’s foot to control image navigation, review, positioning, and viewing, functions; a computer; and a user interface.
