An information processing system comprises: an information processor capable of transmitting and receiving data; and an estimation unit that estimates dental notations of teeth in each of visible light images and X-ray images of oral cavities input through the information processor and estimates image shooting direction of each of the visible light images and the X-ray images. The information processor adds the dental notations and the image sensing direction to each of the visible light images and the X-ray images as metadata, and manages the visible light images and the X-ray images by associating the visible light images and the X-ray images using the metadata.

In an embodiment, the method includes acquiring first position data relating to an outer contour of an object, via at least one measuring device arranged on a gantry of a medical imaging device; receiving second position data relating to an inner contour of an opening of the gantry and/or an outer contour of the gantry; receiving movement data relating to relative movement between the gantry and the object; calculating the collision information relating to a collision of the object and the gantry, based on the first position data, the second position data and the movement data; and providing the collision information.

Hybrid detection systems and methods for C-arm interventional x-ray systems are provided. The hybrid detection system can have a changeable x-ray detection system that is coupled to an integrated within a C-arm x-ray imaging system. The changeable x-ray detector system can include an energy-integrating x-ray detector, and a photon-counting x-ray detector. The C-arm x-ray imaging system using only one detector at a time to acquire x-ray imaging data.

The radiography apparatus includes: an irradiation unit having an irradiation opening through which radiation is emitted; an image receiving unit that has an image receiving surface receiving the radiation emitted from the irradiation unit; an arm that has one end at which the irradiation unit is rotatably supported and the other end at which the image receiving unit is supported in a posture in which the irradiation opening and the image receiving surface face each other; a solenoid that locks the rotation of the irradiation unit with respect to the arm in a facing posture in which the irradiation opening and the image receiving surface face each other; and a control unit that permits the moving image capture irradiation in a state in which the rotation of the irradiation unit is locked and prohibits the moving image capture irradiation in a state in which the rotation is unlocked.

Methods and systems are provided for reconstruction error assessment for an interventional tool utilized in an image guided interventional procedure. In one example, an error model based on a target lesion position within a tissue, one or more interventional tool parameters, and imaging system parameters may be utilized to estimate an expected reconstruction error for the interventional tool. In another example, when the interventional tool is within the tissue, the expected reconstruction error may be utilized along with observed tool shape and size to infer an actual tool position and shape within the tissue.

A console includes a CPU and a GPU. Of the CPU and GPU, the CPU acquires an image to be processed, which is an object to be subjected to a support process that is a diagnosis support process or an imaging support process, and distributes a process to any one of the CPU, the GPU, or another GPU to execute the support process according to the content of the support process executed for the image to be processed.

An X-ray diagnosis apparatus according to an embodiment includes processing circuitry configured: to detect an element from X-ray image data taken of an examined subject; to determine a parameter of multi-frequency processing on the basis of a detection result of the element; and to execute the multi-frequency processing on one or both of the X-ray image data and another piece of X-ray image data taken later than the X-ray image data, on the basis of the determined parameter.

Methods and systems are provided for extracting cardiac frequency angiographic phenomena for an unconstrained vascular object from an angiographic study. In one example, a computer may obtain a series of angiographic image frames obtained at a rate faster than cardiac frequency. Each image frame may comprise a plurality of pixels, and each pixel may have a corresponding intensity. The computer may apply an optical flow technique to the angiographic image frames to generate a plurality of paths corresponding to a displacement of respective pixels from image frame to image frame. The computer may further generate a spatiotemporal reconstruction of cardiac frequency angiographic phenomena based on the plurality of paths and the corresponding intensities associated with respective pixels of the paths, and output for display the spatiotemporal reconstruction of cardiac frequency angiographic phenomena in one or more images.

Systems and methods for tomosynthesis with an x-ray filter are disclosed. The present technology provides performing breast tomosynthesis in the presence of an x-ray filter. For example, an x-ray filter may be placed between an x-ray source and breast tissue. The filter may proportionally filter out a subset of the energies emitted by the x-ray source. A filter may include characteristics to filter x-ray energies based on a k-edge of a contrast agent introduced into the breast, such that the breast tissue has relatively greater exposure to x-ray energies above the k-edge of the contrast agent to illuminate the contrast agent without substantial illumination of other breast tissue. Thus, tomosynthesis images similar to those obtained using subtraction may be acquired without software-based contrast enhancing techniques.
